Writing an Abstract for Your Research Paper

Definition and Purpose of Abstracts

An abstract is a short summary of your (published or unpublished) research paper, usually about a paragraph (c. 6-7 sentences, 150-250 words) long. A well-written abstract serves multiple purposes:

• an abstract lets readers get the gist or essence of your paper or article quickly, in order to decide whether to read the full paper;
• an abstract prepares readers to follow the detailed information, analyses, and arguments in your full paper;
• and, later, an abstract helps readers remember key points from your paper.

It’s also worth remembering that search engines and bibliographic databases use abstracts, as well as the title, to identify key terms for indexing your published paper. So what you include in your abstract and in your title are crucial for helping other researchers find your paper or article.

If you are writing an abstract for a course paper, your professor may give you specific guidelines for what to include and how to organize your abstract. Similarly, academic journals often have specific requirements for abstracts. So in addition to following the advice on this page, you should be sure to look for and follow any guidelines from the course or journal you’re writing for.

The Contents of an Abstract

Abstracts contain most of the following kinds of information in brief form. The body of your paper will, of course, develop and explain these ideas much more fully. As you will see in the samples below, the proportion of your abstract that you devote to each kind of information—and the sequence of that information—will vary, depending on the nature and genre of the paper that you are summarizing in your abstract. And in some cases, some of this information is implied, rather than stated explicitly. The Publication Manual of the American Psychological Association , which is widely used in the social sciences, gives specific guidelines for what to include in the abstract for different kinds of papers—for empirical studies, literature reviews or meta-analyses, theoretical papers, methodological papers, and case studies.

Here are the typical kinds of information found in most abstracts:

• the context or background information for your research; the general topic under study; the specific topic of your research
• the central questions or statement of the problem your research addresses
• what’s already known about this question, what previous research has done or shown
• the main reason(s) , the exigency, the rationale , the goals for your research—Why is it important to address these questions? Are you, for example, examining a new topic? Why is that topic worth examining? Are you filling a gap in previous research? Applying new methods to take a fresh look at existing ideas or data? Resolving a dispute within the literature in your field? . . .
• your research and/or analytical methods
• your main findings , results , or arguments
• the significance or implications of your findings or arguments.

Your abstract should be intelligible on its own, without a reader’s having to read your entire paper. And in an abstract, you usually do not cite references—most of your abstract will describe what you have studied in your research and what you have found and what you argue in your paper. In the body of your paper, you will cite the specific literature that informs your research.

When to Write Your Abstract

Although you might be tempted to write your abstract first because it will appear as the very first part of your paper, it’s a good idea to wait to write your abstract until after you’ve drafted your full paper, so that you know what you’re summarizing.

What follows are some sample abstracts in published papers or articles, all written by faculty at UW-Madison who come from a variety of disciplines. We have annotated these samples to help you see the work that these authors are doing within their abstracts.

Choosing Verb Tenses within Your Abstract

The social science sample (Sample 1) below uses the present tense to describe general facts and interpretations that have been and are currently true, including the prevailing explanation for the social phenomenon under study. That abstract also uses the present tense to describe the methods, the findings, the arguments, and the implications of the findings from their new research study. The authors use the past tense to describe previous research.

The humanities sample (Sample 2) below uses the past tense to describe completed events in the past (the texts created in the pulp fiction industry in the 1970s and 80s) and uses the present tense to describe what is happening in those texts, to explain the significance or meaning of those texts, and to describe the arguments presented in the article.

The science samples (Samples 3 and 4) below use the past tense to describe what previous research studies have done and the research the authors have conducted, the methods they have followed, and what they have found. In their rationale or justification for their research (what remains to be done), they use the present tense. They also use the present tense to introduce their study (in Sample 3, “Here we report . . .”) and to explain the significance of their study (In Sample 3, This reprogramming . . . “provides a scalable cell source for. . .”).

Sample Abstract 4, a Structured Abstract

Reporting results about the effectiveness of antibiotic therapy in managing acute bacterial sinusitis, from a rigorously controlled study

Note: This journal requires authors to organize their abstract into four specific sections, with strict word limits. Because the headings for this structured abstract are self-explanatory, we have chosen not to add annotations to this sample abstract.

Wald, Ellen R., David Nash, and Jens Eickhoff. “Effectiveness of Amoxicillin/Clavulanate Potassium in the Treatment of Acute Bacterial Sinusitis in Children.” Pediatrics , vol. 124, no. 1, 2009, pp. 9-15.

“OBJECTIVE: The role of antibiotic therapy in managing acute bacterial sinusitis (ABS) in children is controversial. The purpose of this study was to determine the effectiveness of high-dose amoxicillin/potassium clavulanate in the treatment of children diagnosed with ABS.

METHODS : This was a randomized, double-blind, placebo-controlled study. Children 1 to 10 years of age with a clinical presentation compatible with ABS were eligible for participation. Patients were stratified according to age (<6 or ≥6 years) and clinical severity and randomly assigned to receive either amoxicillin (90 mg/kg) with potassium clavulanate (6.4 mg/kg) or placebo. A symptom survey was performed on days 0, 1, 2, 3, 5, 7, 10, 20, and 30. Patients were examined on day 14. Children’s conditions were rated as cured, improved, or failed according to scoring rules.

RESULTS: Two thousand one hundred thirty-five children with respiratory complaints were screened for enrollment; 139 (6.5%) had ABS. Fifty-eight patients were enrolled, and 56 were randomly assigned. The mean age was 6630 months. Fifty (89%) patients presented with persistent symptoms, and 6 (11%) presented with nonpersistent symptoms. In 24 (43%) children, the illness was classified as mild, whereas in the remaining 32 (57%) children it was severe. Of the 28 children who received the antibiotic, 14 (50%) were cured, 4 (14%) were improved, 4(14%) experienced treatment failure, and 6 (21%) withdrew. Of the 28children who received placebo, 4 (14%) were cured, 5 (18%) improved, and 19 (68%) experienced treatment failure. Children receiving the antibiotic were more likely to be cured (50% vs 14%) and less likely to have treatment failure (14% vs 68%) than children receiving the placebo.

CONCLUSIONS : ABS is a common complication of viral upper respiratory infections. Amoxicillin/potassium clavulanate results in significantly more cures and fewer failures than placebo, according to parental report of time to resolution.” (9)

Formatting instructions

Follow these five steps to format your abstract in APA Style:

• Insert a running head (for a professional paper—not needed for a student paper) and page number.
• Set page margins to 1 inch (2.54 cm).
• Write “Abstract” (bold and centered) at the top of the page.
• Do not indent the first line.
• Double-space the text.
• Use a legible font like Times New Roman (12 pt.).
• Limit the length to 250 words.
• Indent the first line 0.5 inches.
• Write the label “Keywords:” (italicized).
• Write keywords in lowercase letters.
• Separate keywords with commas.
• Do not use a period after the keywords.

Prevent plagiarism. Run a free check.

The abstract is a self-contained piece of text that informs the reader what your research is about. It’s best to write the abstract after you’re finished with the rest of your paper.

The questions below may help structure your abstract. Try answering them in one to three sentences each.

• What is the problem? Outline the objective, research questions , and/or hypotheses .
• What has been done? Explain your research methods .
• What did you discover? Summarize the key findings and conclusions .
• What do the findings mean? Summarize the discussion and recommendations .

Check out our guide on how to write an abstract for more guidance and an annotated example.

Guide: writing an abstract

At the end of the abstract, you may include a few keywords that will be used for indexing if your paper is published on a database. Listing your keywords will help other researchers find your work.

Choosing relevant keywords is essential. Try to identify keywords that address your topic, method, or population. APA recommends including three to five keywords.

An abstract is a concise summary of an academic text (such as a journal article or dissertation ). It serves two main purposes:

• To help potential readers determine the relevance of your paper for their own research.
• To communicate your key findings to those who don’t have time to read the whole paper.

Abstracts are often indexed along with keywords on academic databases, so they make your work more easily findable. Since the abstract is the first thing any reader sees, it’s important that it clearly and accurately summarizes the contents of your paper.

An APA abstract is around 150–250 words long. However, always check your target journal’s guidelines and don’t exceed the specified word count.

In an APA Style paper , the abstract is placed on a separate page after the title page (page 2).

Avoid citing sources in your abstract . There are two reasons for this:

• The abstract should focus on your original research, not on the work of others.
• The abstract should be self-contained and fully understandable without reference to other sources.

There are some circumstances where you might need to mention other sources in an abstract: for example, if your research responds directly to another study or focuses on the work of a single theorist. In general, though, don’t include citations unless absolutely necessary.

Research Paper Abstract Examples

Research Paper Abstract Examples could be following:

Title : “The Effectiveness of Cognitive-Behavioral Therapy for Treating Anxiety Disorders: A Meta-Analysis”

Abstract : This meta-analysis examines the effectiveness of cognitive-behavioral therapy (CBT) in treating anxiety disorders. Through the analysis of 20 randomized controlled trials, we found that CBT is a highly effective treatment for anxiety disorders, with large effect sizes across a range of anxiety disorders, including generalized anxiety disorder, panic disorder, and social anxiety disorder. Our findings support the use of CBT as a first-line treatment for anxiety disorders and highlight the importance of further research to identify the mechanisms underlying its effectiveness.

Title : “Exploring the Role of Parental Involvement in Children’s Education: A Qualitative Study”

Abstract : This qualitative study explores the role of parental involvement in children’s education. Through in-depth interviews with 20 parents of children in elementary school, we found that parental involvement takes many forms, including volunteering in the classroom, helping with homework, and communicating with teachers. We also found that parental involvement is influenced by a range of factors, including parent and child characteristics, school culture, and socio-economic status. Our findings suggest that schools and educators should prioritize building strong partnerships with parents to support children’s academic success.

Title : “The Impact of Exercise on Cognitive Function in Older Adults: A Systematic Review and Meta-Analysis”

Abstract : This paper presents a systematic review and meta-analysis of the existing literature on the impact of exercise on cognitive function in older adults. Through the analysis of 25 randomized controlled trials, we found that exercise is associated with significant improvements in cognitive function, particularly in the domains of executive function and attention. Our findings highlight the potential of exercise as a non-pharmacological intervention to support cognitive health in older adults.

When to Write Research Paper Abstract

The abstract of a research paper should typically be written after you have completed the main body of the paper. This is because the abstract is intended to provide a brief summary of the key points and findings of the research, and you can’t do that until you have completed the research and written about it in detail.

Once you have completed your research paper, you can begin writing your abstract. It is important to remember that the abstract should be a concise summary of your research paper, and should be written in a way that is easy to understand for readers who may not have expertise in your specific area of research.

Purpose of Research Paper Abstract

The purpose of a research paper abstract is to provide a concise summary of the key points and findings of a research paper. It is typically a brief paragraph or two that appears at the beginning of the paper, before the introduction, and is intended to give readers a quick overview of the paper’s content.

The abstract should include a brief statement of the research problem, the methods used to investigate the problem, the key results and findings, and the main conclusions and implications of the research. It should be written in a clear and concise manner, avoiding jargon and technical language, and should be understandable to a broad audience.

The abstract serves as a way to quickly and easily communicate the main points of a research paper to potential readers, such as academics, researchers, and students, who may be looking for information on a particular topic. It can also help researchers determine whether a paper is relevant to their own research interests and whether they should read the full paper.

How to Write an Abstract (With Examples)

By Sarah Oakley

Table of Contents

What is an abstract in a paper, how long should an abstract be, 5 steps for writing an abstract, examples of an abstract, how prowritingaid can help you write an abstract.

If you are writing a scientific research paper or a book proposal, you need to know how to write an abstract, which summarizes the contents of the paper or book.

When researchers are looking for peer-reviewed papers to use in their studies, the first place they will check is the abstract to see if it applies to their work. Therefore, your abstract is one of the most important parts of your entire paper.

In this article, we’ll explain what an abstract is, what it should include, and how to write one.

An abstract is a concise summary of the details within a report. Some abstracts give more details than others, but the main things you’ll be talking about are why you conducted the research, what you did, and what the results show.

When a reader is deciding whether to read your paper completely, they will first look at the abstract. You need to be concise in your abstract and give the reader the most important information so they can determine if they want to read the whole paper.

Remember that an abstract is the last thing you’ll want to write for the research paper because it directly references parts of the report. If you haven’t written the report, you won’t know what to include in your abstract.

If you are writing a paper for a journal or an assignment, the publication or academic institution might have specific formatting rules for how long your abstract should be. However, if they don’t, most abstracts are between 150 and 300 words long.

A short word count means your writing has to be precise and without filler words or phrases. Once you’ve written a first draft, you can always use an editing tool, such as ProWritingAid, to identify areas where you can reduce words and increase readability.

If your abstract is over the word limit, and you’ve edited it but still can’t figure out how to reduce it further, your abstract might include some things that aren’t needed. Here’s a list of three elements you can remove from your abstract:

Discussion : You don’t need to go into detail about the findings of your research because your reader will find your discussion within the paper.

Definition of terms : Your readers are interested the field you are writing about, so they are likely to understand the terms you are using. If not, they can always look them up. Your readers do not expect you to give a definition of terms in your abstract.

References and citations : You can mention there have been studies that support or have inspired your research, but you do not need to give details as the reader will find them in your bibliography.

Good writing = better grades

ProWritingAid will help you improve the style, strength, and clarity of all your assignments.

If you’ve never written an abstract before, and you’re wondering how to write an abstract, we’ve got some steps for you to follow. It’s best to start with planning your abstract, so we’ve outlined the details you need to include in your plan before you write.

Remember to consider your audience when you’re planning and writing your abstract. They are likely to skim read your abstract, so you want to be sure your abstract delivers all the information they’re expecting to see at key points.

1. What Should an Abstract Include?

Abstracts have a lot of information to cover in a short number of words, so it’s important to know what to include. There are three elements that need to be present in your abstract:

Your context is the background for where your research sits within your field of study. You should briefly mention any previous scientific papers or experiments that have led to your hypothesis and how research develops in those studies.

Your hypothesis is your prediction of what your study will show. As you are writing your abstract after you have conducted your research, you should still include your hypothesis in your abstract because it shows the motivation for your paper.

Throughout your abstract, you also need to include keywords and phrases that will help researchers to find your article in the databases they’re searching. Make sure the keywords are specific to your field of study and the subject you’re reporting on, otherwise your article might not reach the relevant audience.

2. Can You Use First Person in an Abstract?

You might think that first person is too informal for a research paper, but it’s not. Historically, writers of academic reports avoided writing in first person to uphold the formality standards of the time. However, first person is more accepted in research papers in modern times.

If you’re still unsure whether to write in first person for your abstract, refer to any style guide rules imposed by the journal you’re writing for or your teachers if you are writing an assignment.

3. Abstract Structure

Some scientific journals have strict rules on how to structure an abstract, so it’s best to check those first. If you don’t have any style rules to follow, try using the IMRaD structure, which stands for Introduction, Methodology, Results, and Discussion.

Following the IMRaD structure, start with an introduction. The amount of background information you should include depends on your specific research area. Adding a broad overview gives you less room to include other details. Remember to include your hypothesis in this section.

The next part of your abstract should cover your methodology. Try to include the following details if they apply to your study:

What type of research was conducted?

How were the test subjects sampled?

What were the sample sizes?

What was done to each group?

How long was the experiment?

How was data recorded and interpreted?

Following the methodology, include a sentence or two about the results, which is where your reader will determine if your research supports or contradicts their own investigations.

The results are also where most people will want to find out what your outcomes were, even if they are just mildly interested in your research area. You should be specific about all the details but as concise as possible.

The last few sentences are your conclusion. It needs to explain how your findings affect the context and whether your hypothesis was correct. Include the primary take-home message, additional findings of importance, and perspective. Also explain whether there is scope for further research into the subject of your report.

Your conclusion should be honest and give the reader the ultimate message that your research shows. Readers trust the conclusion, so make sure you’re not fabricating the results of your research. Some readers won’t read your entire paper, but this section will tell them if it’s worth them referencing it in their own study.

4. How to Start an Abstract

The first line of your abstract should give your reader the context of your report by providing background information. You can use this sentence to imply the motivation for your research.

You don’t need to use a hook phrase or device in your first sentence to grab the reader’s attention. Your reader will look to establish relevance quickly, so readability and clarity are more important than trying to persuade the reader to read on.

5. How to Format an Abstract

Most abstracts use the same formatting rules, which help the reader identify the abstract so they know where to look for it.

Here’s a list of formatting guidelines for writing an abstract:

Stick to one paragraph

Use block formatting with no indentation at the beginning

Put your abstract straight after the title and acknowledgements pages

Use present or past tense, not future tense

There are two primary types of abstract you could write for your paper—descriptive and informative.

An informative abstract is the most common, and they follow the structure mentioned previously. They are longer than descriptive abstracts because they cover more details.

Descriptive abstracts differ from informative abstracts, as they don’t include as much discussion or detail. The word count for a descriptive abstract is between 50 and 150 words.

Here is an example of an informative abstract:

A growing trend exists for authors to employ a more informal writing style that uses “we” in academic writing to acknowledge one’s stance and engagement. However, few studies have compared the ways in which the first-person pronoun “we” is used in the abstracts and conclusions of empirical papers. To address this lacuna in the literature, this study conducted a systematic corpus analysis of the use of “we” in the abstracts and conclusions of 400 articles collected from eight leading electrical and electronic (EE) engineering journals. The abstracts and conclusions were extracted to form two subcorpora, and an integrated framework was applied to analyze and seek to explain how we-clusters and we-collocations were employed. Results revealed whether authors’ use of first-person pronouns partially depends on a journal policy. The trend of using “we” showed that a yearly increase occurred in the frequency of “we” in EE journal papers, as well as the existence of three “we-use” types in the article conclusions and abstracts: exclusive, inclusive, and ambiguous. Other possible “we-use” alternatives such as “I” and other personal pronouns were used very rarely—if at all—in either section. These findings also suggest that the present tense was used more in article abstracts, but the present perfect tense was the most preferred tense in article conclusions. Both research and pedagogical implications are proffered and critically discussed.

Wang, S., Tseng, W.-T., & Johanson, R. (2021). To We or Not to We: Corpus-Based Research on First-Person Pronoun Use in Abstracts and Conclusions. SAGE Open, 11(2).

Here is an example of a descriptive abstract:

From the 1850s to the present, considerable criminological attention has focused on the development of theoretically-significant systems for classifying crime. This article reviews and attempts to evaluate a number of these efforts, and we conclude that further work on this basic task is needed. The latter part of the article explicates a conceptual foundation for a crime pattern classification system, and offers a preliminary taxonomy of crime.

If you want to ensure your abstract is grammatically correct and easy to read, you can use ProWritingAid to edit it. The software integrates with Microsoft Word, Google Docs, and most web browsers, so you can make the most of it wherever you’re writing your paper.

Before you edit with ProWritingAid, make sure the suggestions you are seeing are relevant for your document by changing the document type to “Abstract” within the Academic writing style section.

You can use the Readability report to check your abstract for places to improve the clarity of your writing. Some suggestions might show you where to remove words, which is great if you’re over your word count.

We hope the five steps and examples we’ve provided help you write a great abstract for your research paper.

Abstract Writing: A Step-by-Step Guide With Tips & Examples

Table of Contents

Introduction

Abstracts of research papers have always played an essential role in describing your research concisely and clearly to researchers and editors of journals, enticing them to continue reading. However, with the widespread availability of scientific databases, the need to write a convincing abstract is more crucial now than during the time of paper-bound manuscripts.

Abstracts serve to "sell" your research and can be compared with your "executive outline" of a resume or, rather, a formal summary of the critical aspects of your work. Also, it can be the "gist" of your study. Since most educational research is done online, it's a sign that you have a shorter time for impressing your readers, and have more competition from other abstracts that are available to be read.

The APCI (Academic Publishing and Conferences International) articulates 12 issues or points considered during the final approval process for conferences & journals and emphasises the importance of writing an abstract that checks all these boxes (12 points). Since it's the only opportunity you have to captivate your readers, you must invest time and effort in creating an abstract that accurately reflects the critical points of your research.

With that in mind, let’s head over to understand and discover the core concept and guidelines to create a substantial abstract. Also, learn how to organise the ideas or plots into an effective abstract that will be awe-inspiring to the readers you want to reach.

What is Abstract? Definition and Overview

The word "Abstract' is derived from Latin abstractus meaning "drawn off." This etymological meaning also applies to art movements as well as music, like abstract expressionism. In this context, it refers to the revealing of the artist's intention.

Based on this, you can determine the meaning of an abstract: A condensed research summary. It must be self-contained and independent of the body of the research. However, it should outline the subject, the strategies used to study the problem, and the methods implemented to attain the outcomes. The specific elements of the study differ based on the area of study; however, together, it must be a succinct summary of the entire research paper.

Abstracts are typically written at the end of the paper, even though it serves as a prologue. In general, the abstract must be in a position to:

• Describe the paper.
• Identify the problem or the issue at hand.
• Explain to the reader the research process, the results you came up with, and what conclusion you've reached using these results.
• Include keywords to guide your strategy and the content.

Furthermore, the abstract you submit should not reflect upon any of  the following elements:

• Examine, analyse or defend the paper or your opinion.
• What you want to study, achieve or discover.
• Be redundant or irrelevant.

After reading an abstract, your audience should understand the reason - what the research was about in the first place, what the study has revealed and how it can be utilised or can be used to benefit others. You can understand the importance of abstract by knowing the fact that the abstract is the most frequently read portion of any research paper. In simpler terms, it should contain all the main points of the research paper.

What is the Purpose of an Abstract?

Abstracts are typically an essential requirement for research papers; however, it's not an obligation to preserve traditional reasons without any purpose. Abstracts allow readers to scan the text to determine whether it is relevant to their research or studies. The abstract allows other researchers to decide if your research paper can provide them with some additional information. A good abstract paves the interest of the audience to pore through your entire paper to find the content or context they're searching for.

Abstract writing is essential for indexing, as well. The Digital Repository of academic papers makes use of abstracts to index the entire content of academic research papers. Like meta descriptions in the regular Google outcomes, abstracts must include keywords that help researchers locate what they seek.

Types of Abstract

Informative and Descriptive are two kinds of abstracts often used in scientific writing.

A descriptive abstract gives readers an outline of the author's main points in their study. The reader can determine if they want to stick to the research work, based on their interest in the topic. An abstract that is descriptive is similar to the contents table of books, however, the format of an abstract depicts complete sentences encapsulated in one paragraph. It is unfortunate that the abstract can't be used as a substitute for reading a piece of writing because it's just an overview, which omits readers from getting an entire view. Also, it cannot be a way to fill in the gaps the reader may have after reading this kind of abstract since it does not contain crucial information needed to evaluate the article.

To conclude, a descriptive abstract is:

• A simple summary of the task, just summarises the work, but some researchers think it is much more of an outline
• Typically, the length is approximately 100 words. It is too short when compared to an informative abstract.
• A brief explanation but doesn't provide the reader with the complete information they need;
• An overview that omits conclusions and results

An informative abstract is a comprehensive outline of the research. There are times when people rely on the abstract as an information source. And the reason is why it is crucial to provide entire data of particular research. A well-written, informative abstract could be a good substitute for the remainder of the paper on its own.

A well-written abstract typically follows a particular style. The author begins by providing the identifying information, backed by citations and other identifiers of the papers. Then, the major elements are summarised to make the reader aware of the study. It is followed by the methodology and all-important findings from the study. The conclusion then presents study results and ends the abstract with a comprehensive summary.

In a nutshell, an informative abstract:

• Has a length that can vary, based on the subject, but is not longer than 300 words.
• Contains all the content-like methods and intentions
• Offers evidence and possible recommendations.

Informative Abstracts are more frequent than descriptive abstracts because of their extensive content and linkage to the topic specifically. You should select different types of abstracts to papers based on their length: informative abstracts for extended and more complex abstracts and descriptive ones for simpler and shorter research papers.

What are the Characteristics of a Good Abstract?

• A good abstract clearly defines the goals and purposes of the study.
• It should clearly describe the research methodology with a primary focus on data gathering, processing, and subsequent analysis.
• A good abstract should provide specific research findings.
• It presents the principal conclusions of the systematic study.
• It should be concise, clear, and relevant to the field of study.
• A well-designed abstract should be unifying and coherent.
• It is easy to grasp and free of technical jargon.
• It is written impartially and objectively.

What are the various sections of an ideal Abstract?

By now, you must have gained some concrete idea of the essential elements that your abstract needs to convey . Accordingly, the information is broken down into six key sections of the abstract, which include:

An Introduction or Background

Research methodology, objectives and goals, limitations.

Let's go over them in detail.

The introduction, also known as background, is the most concise part of your abstract. Ideally, it comprises a couple of sentences. Some researchers only write one sentence to introduce their abstract. The idea behind this is to guide readers through the key factors that led to your study.

It's understandable that this information might seem difficult to explain in a couple of sentences. For example, think about the following two questions like the background of your study:

• What is currently available about the subject with respect to the paper being discussed?
• What isn't understood about this issue? (This is the subject of your research)

While writing the abstract’s introduction, make sure that it is not lengthy. Because if it crosses the word limit, it may eat up the words meant to be used for providing other key information.

Research methodology is where you describe the theories and techniques you used in your research. It is recommended that you describe what you have done and the method you used to get your thorough investigation results. Certainly, it is the second-longest paragraph in the abstract.

In the research methodology section, it is essential to mention the kind of research you conducted; for instance, qualitative research or quantitative research (this will guide your research methodology too) . If you've conducted quantitative research, your abstract should contain information like the sample size, data collection method, sampling techniques, and duration of the study. Likewise, your abstract should reflect observational data, opinions, questionnaires (especially the non-numerical data) if you work on qualitative research.

The research objectives and goals speak about what you intend to accomplish with your research. The majority of research projects focus on the long-term effects of a project, and the goals focus on the immediate, short-term outcomes of the research. It is possible to summarise both in just multiple sentences.

In stating your objectives and goals, you give readers a picture of the scope of the study, its depth and the direction your research ultimately follows. Your readers can evaluate the results of your research against the goals and stated objectives to determine if you have achieved the goal of your research.

In the end, your readers are more attracted by the results you've obtained through your study. Therefore, you must take the time to explain each relevant result and explain how they impact your research. The results section exists as the longest in your abstract, and nothing should diminish its reach or quality.

One of the most important things you should adhere to is to spell out details and figures on the results of your research.

Instead of making a vague assertion such as, "We noticed that response rates varied greatly between respondents with high incomes and those with low incomes", Try these: "The response rate was higher for high-income respondents than those with lower incomes (59 30 percent vs. 30 percent in both cases; P<0.01)."

You're likely to encounter certain obstacles during your research. It could have been during data collection or even during conducting the sample . Whatever the issue, it's essential to inform your readers about them and their effects on the research.

Research limitations offer an opportunity to suggest further and deep research. If, for instance, you were forced to change for convenient sampling and snowball samples because of difficulties in reaching well-suited research participants, then you should mention this reason when you write your research abstract. In addition, a lack of prior studies on the subject could hinder your research.

Your conclusion should include the same number of sentences to wrap the abstract as the introduction. The majority of researchers offer an idea of the consequences of their research in this case.

Your conclusion should include three essential components:

• A significant take-home message.
• Corresponding important findings.
• The Interpretation.

Even though the conclusion of your abstract needs to be brief, it can have an enormous influence on the way that readers view your research. Therefore, make use of this section to reinforce the central message from your research. Be sure that your statements reflect the actual results and the methods you used to conduct your research.

Good Abstract Examples

Abstract example #1.

Children’s consumption behavior in response to food product placements in movies.

The abstract:

"Almost all research into the effects of brand placements on children has focused on the brand's attitudes or behavior intentions. Based on the significant differences between attitudes and behavioral intentions on one hand and actual behavior on the other hand, this study examines the impact of placements by brands on children's eating habits. Children aged 6-14 years old were shown an excerpt from the popular film Alvin and the Chipmunks and were shown places for the item Cheese Balls. Three different versions were developed with no placements, one with moderately frequent placements and the third with the highest frequency of placement. The results revealed that exposure to high-frequency places had a profound effect on snack consumption, however, there was no impact on consumer attitudes towards brands or products. The effects were not dependent on the age of the children. These findings are of major importance to researchers studying consumer behavior as well as nutrition experts as well as policy regulators."

Abstract Example #2

Social comparisons on social media: The impact of Facebook on young women’s body image concerns and mood. The abstract:

"The research conducted in this study investigated the effects of Facebook use on women's moods and body image if the effects are different from an internet-based fashion journal and if the appearance comparison tendencies moderate one or more of these effects. Participants who were female ( N = 112) were randomly allocated to spend 10 minutes exploring their Facebook account or a magazine's website or an appearance neutral control website prior to completing state assessments of body dissatisfaction, mood, and differences in appearance (weight-related and facial hair, face, and skin). Participants also completed a test of the tendency to compare appearances. The participants who used Facebook were reported to be more depressed than those who stayed on the control site. In addition, women who have the tendency to compare appearances reported more facial, hair and skin-related issues following Facebook exposure than when they were exposed to the control site. Due to its popularity it is imperative to conduct more research to understand the effect that Facebook affects the way people view themselves."

Abstract Example #3

The Relationship Between Cell Phone Use and Academic Performance in a Sample of U.S. College Students

"The cellphone is always present on campuses of colleges and is often utilised in situations in which learning takes place. The study examined the connection between the use of cell phones and the actual grades point average (GPA) after adjusting for predictors that are known to be a factor. In the end 536 students in the undergraduate program from 82 self-reported majors of an enormous, public institution were studied. Hierarchical analysis ( R 2 = .449) showed that use of mobile phones is significantly ( p < .001) and negative (b equal to -.164) connected to the actual college GPA, after taking into account factors such as demographics, self-efficacy in self-regulated learning, self-efficacy to improve academic performance, and the actual high school GPA that were all important predictors ( p < .05). Therefore, after adjusting for other known predictors increasing cell phone usage was associated with lower academic performance. While more research is required to determine the mechanisms behind these results, they suggest the need to educate teachers and students to the possible academic risks that are associated with high-frequency mobile phone usage."

Quick tips on writing a good abstract

There exists a common dilemma among early age researchers whether to write the abstract at first or last? However, it's recommended to compose your abstract when you've completed the research since you'll have all the information to give to your readers. You can, however, write a draft at the beginning of your research and add in any gaps later.

If you find abstract writing a herculean task, here are the few tips to help you with it:

1. Always develop a framework to support your abstract

Before writing, ensure you create a clear outline for your abstract. Divide it into sections and draw the primary and supporting elements in each one. You can include keywords and a few sentences that convey the essence of your message.

2. Review Other Abstracts

Abstracts are among the most frequently used research documents, and thousands of them were written in the past. Therefore, prior to writing yours, take a look at some examples from other abstracts. There are plenty of examples of abstracts for dissertations in the dissertation and thesis databases.

3. Avoid Jargon To the Maximum

When you write your abstract, focus on simplicity over formality. You should  write in simple language, and avoid excessive filler words or ambiguous sentences. Keep in mind that your abstract must be readable to those who aren't acquainted with your subject.

4. Focus on Your Research

It's a given fact that the abstract you write should be about your research and the findings you've made. It is not the right time to mention secondary and primary data sources unless it's absolutely required.

Conclusion: How to Structure an Interesting Abstract?

Abstracts are a short outline of your essay. However, it's among the most important, if not the most important. The process of writing an abstract is not straightforward. A few early-age researchers tend to begin by writing it, thinking they are doing it to "tease" the next step (the document itself). However, it is better to treat it as a spoiler.

The simple, concise style of the abstract lends itself to a well-written and well-investigated study. If your research paper doesn't provide definitive results, or the goal of your research is questioned, so will the abstract. Thus, only write your abstract after witnessing your findings and put your findings in the context of a larger scenario.

The process of writing an abstract can be daunting, but with these guidelines, you will succeed. The most efficient method of writing an excellent abstract is to centre the primary points of your abstract, including the research question and goals methods, as well as key results.

How to write an abstract

What is an abstract?

General format of an abstract, the content of an abstract, abstract example, abstract style guides, frequently asked questions about writing an abstract, related articles.

An abstract is a summary of the main contents of a paper.

The abstract is the first glimpse that readers get of the content of a research paper. It can influence the popularity of a paper, as a well-written one will attract readers, and a poorly-written one will drive them away.

➡️ Different types of papers may require distinct abstract styles. Visit our guide on the different types of research papers to learn more.

Tip: Always wait until you’ve written your entire paper before you write the abstract.

Before you actually start writing an abstract, make sure to follow these steps:

• Read other papers : find papers with similar topics, or similar methodologies, simply to have an idea of how others have written their abstracts. Notice which points they decided to include, and how in depth they described them.
• Double check the journal requirements : always make sure to review the journal guidelines to format your paper accordingly. Usually, they also specify abstract's formats.
• Write the abstract after you finish writing the paper : you can only write an abstract once you finish writing the whole paper. This way you can include all important aspects, such as scope, methodology, and conclusion.

➡️ Read more about  what is a research methodology?

The general format of an abstract includes the following features:

• Between 150-300 words .
• An independent page , after the title page and before the table of contents.
• Concise summary including the aim of the research, methodology , and conclusion .
• Keywords describing the content.

As mentioned before, an abstract is a text that summarizes the main points of a research. Here is a break down of each element that should be included in an abstract:

• Purpose : every abstract should start by describing the main purpose or aim of the research.
• Methods : as a second point, the methodology carried out should be explained.
• Results : then, a concise summary of the results should be included.
• Conclusion : finally, a short outline of the general outcome of the research should be given.
• Keywords : along with the abstract, specific words and phrases related to the topics discussed in the research should be added. These words are usually around five, but the number can vary depending on the journal's guidelines.

This abstract, taken from ScienceDirect , illustrates the ideal structure of an abstract. It has 155 words, it's concise, and it clearly shows the division of elements necessary to write a successful abstract.

This paper explores the implicit assumption in the growing body of literature that social media usage is fundamentally different in business-to-business (B2B) companies than in the extant business-to-consumer (B2C) literature. Sashi's (2012) customer engagement cycle is utilized to compare organizational practices in relation to social media marketing in B2B, B2C, Mixed B2B/B2C and B2B2C business models. Utilizing 449 responses to an exploratory panel based survey instrument, we clearly identify differences in social media usage and its perceived importance as a communications channel. In particular we identify distinct differences in the relationship between social media importance and the perceived effectiveness of social media marketing across business models. Our results indicate that B2B social media usage is distinct from B2C, Mixed and B2B2C business model approaches. Specifically B2B organizational members perceive social media to have a lower overall effectiveness as a channel and identify it as less important for relationship oriented usage than other business models.

The exact format of an abstract depends on the citation style you implement. Whether it’s a well-known style (like APA, IEEE, etc.) or a journal's style, each format has its own guidelines, so make sure you know which style you are using before writing your abstract.

APA is one of the most commonly used styles to format an abstract. Therefore, we created a guide with exact instructions on how to write an abstract in APA style, and a template to download:

Additionally, you will find below an IEEE and ASA abstract guide by Purdue Online Writing Lab :

📗 IEEE General Format - Abstract

📘 ASA Manuscript Formatting - Abstract

No. You should always write an abstract once you finish writing the whole paper. This way you can include all important aspects of the paper, such as scope, methodology, and conclusion.

The length of an abstract depends on the formatting style of the paper. For example, APA style calls for 150 to 250 words. Generally, you need between 150-300 words.

No. An abstract has an independent section after the title page and before the table of contents, and should not be included in the table of contents.

Writing an abstract - a six point checklist (with samples)

Posted in: abstract , dissertations

The abstract is a vital part of any research paper. It is the shop front for your work, and the first stop for your reader. It should provide a clear and succinct summary of your study, and encourage your readers to read more. An effective abstract, therefore should answer the following questions:

• Why did you do this study or project?
• What did you do and how?
• What did you find?
• What do your findings mean?

So here's our run down of the key elements of a well-written abstract.

• Size - A succinct and well written abstract should be between approximately 100- 250 words.
• Background - An effective abstract usually includes some scene-setting information which might include what is already known about the subject, related to the paper in question (a few short sentences).
• Purpose  - The abstract should also set out the purpose of your research, in other words, what is not known about the subject and hence what the study intended to examine (or what the paper seeks to present).
• Methods - The methods section should contain enough information to enable the reader to understand what was done, and how. It should include brief details of the research design, sample size, duration of study, and so on.
• Results - The results section is the most important part of the abstract. This is because readers who skim an abstract do so to learn about the findings of the study. The results section should therefore contain as much detail about the findings as the journal word count permits.
• Conclusion - This section should contain the most important take-home message of the study, expressed in a few precisely worded sentences. Usually, the finding highlighted here relates to the primary outcomes of the study. However, other important or unexpected findings should also be mentioned. It is also customary, but not essential, to express an opinion about the theoretical or practical implications of the findings, or the importance of their findings for the field. Thus, the conclusions may contain three elements:
• The primary take-home message.
• Any additional findings of importance.
• Implications for future studies.

Example Abstract 2: Engineering Development and validation of a three-dimensional finite element model of the pelvic bone.

Abstract from: Dalstra, M., Huiskes, R. and Van Erning, L., 1995. Development and validation of a three-dimensional finite element model of the pelvic bone. Journal of biomechanical engineering, 117(3), pp.272-278.

And finally...  A word on abstract types and styles

Abstract types can differ according to subject discipline. You need to determine therefore which type of abstract you should include with your paper. Here are two of the most common types with examples.

Informative Abstract

The majority of abstracts are informative. While they still do not critique or evaluate a work, they do more than describe it. A good informative abstract acts as a surrogate for the work itself. That is, the researcher presents and explains all the main arguments and the important results and evidence in the paper. An informative abstract includes the information that can be found in a descriptive abstract [purpose, methods, scope] but it also includes the results and conclusions of the research and the recommendations of the author. The length varies according to discipline, but an informative abstract is usually no more than 300 words in length.

Descriptive Abstract A descriptive abstract indicates the type of information found in the work. It makes no judgements about the work, nor does it provide results or conclusions of the research. It does incorporate key words found in the text and may include the purpose, methods, and scope of the research. Essentially, the descriptive abstract only describes the work being summarised. Some researchers consider it an outline of the work, rather than a summary. Descriptive abstracts are usually very short, 100 words or less.

How to Write an Abstract for a Research Paper | Examples

What is a research paper abstract?

Research paper abstracts summarize your study quickly and succinctly to journal editors and researchers and prompt them to read further. But with the ubiquity of online publication databases, writing a compelling abstract is even more important today than it was in the days of bound paper manuscripts.

Abstracts exist to “sell”  your work, and they could thus be compared to the “executive summary” of a business resume: an official briefing on what is most important about your research. Or the “gist” of your research. With the majority of academic transactions being conducted online, this means that you have even less time to impress readers–and increased competition in terms of other abstracts out there to read.

The APCI (Academic Publishing and Conferences International) notes that there are  12 questions or “points” considered in the selection process  for journals and conferences and stresses the importance of having an abstract that ticks all of these boxes. Because it is often the ONLY chance you have to convince readers to keep reading, it is important that you spend time and energy crafting an abstract that faithfully represents the central parts of your study and captivates your audience.

With that in mind, follow these suggestions when structuring and writing your abstract, and learn how exactly to put these ideas into a solid abstract that will captivate your target readers.

Before Writing Your Abstract

How long should an abstract be.

All abstracts are written with the same essential objective: to give a summary of your study. But there are two basic styles of abstract: descriptive and informative . Here is a brief delineation of the two:

Of the two types of abstracts, informative abstracts are much more common, and they are widely used for submission to journals and conferences. Informative abstracts apply to lengthier and more technical research and are common in the sciences, engineering, and psychology, while descriptive abstracts are more likely used in humanities and social science papers. The best method of determining which abstract type you need to use is to follow the instructions for journal submissions and to read as many other published articles in those journals as possible.

Research Abstract Guidelines and Requirements

As any article about research writing will tell you, authors must always closely follow the specific guidelines and requirements indicated in the Guide for Authors section of their target journal’s website. The same kind of adherence to conventions should be applied to journal publications, for consideration at a conference, and even when completing a class assignment.

Each publisher has particular demands when it comes to formatting and structure. Here are some common questions addressed in the journal guidelines:

• Is there a maximum or minimum word/character length?
• What are the style and formatting requirements?
• What is the appropriate abstract type?
• Are there any specific content or organization rules that apply?

There are of course other rules to consider when composing a research paper abstract. But if you follow the stated rules the first time you submit your manuscript, you can avoid your work being thrown in the “circular file” right off the bat.

Identify Your Target Readership

The main purpose of your abstract is to lead researchers to the full text of your research paper. In scientific journals, abstracts let readers decide whether the research discussed is relevant to their own interests or study. Abstracts also help readers understand your main argument quickly. Consider these questions as you write your abstract:

• Are other academics in your field the main target of your study?
• Will your study perhaps be useful to members of the general public?
• Do your study results include the wider implications presented in the abstract?

Outlining and Writing Your Abstract

What to include in an abstract.

Just as your  research paper title  should cover as much ground as possible in a few short words, your abstract must cover  all  parts of your study in order to fully explain your paper and research. Because it must accomplish this task in the space of only a few hundred words, it is important not to include ambiguous references or phrases that will confuse the reader or mislead them about the content and objectives of your research. Follow these  dos  and  don’ts  when it comes to what kind of writing to include:

• Avoid acronyms or abbreviations since these will need to be explained in order to make sense to the reader, which takes up valuable abstract space. Instead, explain these terms in the Introduction section of the main text.
• Only use references to people or other works if they are well-known. Otherwise, avoid referencing anything outside of your study in the abstract.
• Never include tables, figures, sources, or long quotations in your abstract; you will have plenty of time to present and refer to these in the body of your paper.

Use keywords in your abstract to focus your topic

A vital search tool is the research paper keywords section, which lists the most relevant terms directly underneath the abstract. Think of these keywords as the “tubes” that readers will seek and enter—via queries on databases and search engines—to ultimately land at their destination, which is your paper. Your abstract keywords should thus be words that are commonly used in searches but should also be highly relevant to your work and found in the text of your abstract. Include 5 to 10 important words or short phrases central to your research in both the abstract and the keywords section.

For example, if you are writing a paper on the prevalence of obesity among lower classes that crosses international boundaries, you should include terms like “obesity,” “prevalence,” “international,” “lower classes,” and “cross-cultural.” These are terms that should net a wide array of people interested in your topic of study. Look at our nine rules for choosing keywords for your research paper if you need more input on this.

Research Paper Abstract Structure

As mentioned above, the abstract (especially the informative abstract) acts as a surrogate or synopsis of your research paper, doing almost as much work as the thousands of words that follow it in the body of the main text. In the hard sciences and most social sciences, the abstract includes the following sections and organizational schema.

Each section is quite compact—only a single sentence or two, although there is room for expansion if one element or statement is particularly interesting or compelling. As the abstract is almost always one long paragraph, the individual sections should naturally merge into one another to create a holistic effect. Use the following as a checklist to ensure that you have included all of the necessary content in your abstract.

1) Identify your purpose and motivation

So your research is about rabies in Brazilian squirrels. Why is this important? You should start your abstract by explaining why people should care about this study—why is it significant to your field and perhaps to the wider world? And what is the exact purpose of your study; what are you trying to achieve? Start by answering the following questions:

• What made you decide to do this study or project?
• Why is this study important to your field or to the lay reader?
• Why should someone read your entire article?

In summary, the first section of your abstract should include the importance of the research and its impact on related research fields or on the wider scientific domain.

2) Explain the research problem you are addressing

Stating the research problem that your study addresses is the corollary to why your specific study is important and necessary. For instance, even if the issue of “rabies in Brazilian squirrels” is important, what is the problem—the “missing piece of the puzzle”—that your study helps resolve?

You can combine the problem with the motivation section, but from a perspective of organization and clarity, it is best to separate the two. Here are some precise questions to address:

• What is your research trying to better understand or what problem is it trying to solve?
• What is the scope of your study—does it try to explain something general or specific?
• What is your central claim or argument?

3) Discuss your research approach

Your specific study approach is detailed in the Methods and Materials section .  You have already established the importance of the research, your motivation for studying this issue, and the specific problem your paper addresses. Now you need to discuss  how  you solved or made progress on this problem—how you conducted your research. If your study includes your own work or that of your team, describe that here. If in your paper you reviewed the work of others, explain this here. Did you use analytic models? A simulation? A double-blind study? A case study? You are basically showing the reader the internal engine of your research machine and how it functioned in the study. Be sure to:

• Detail your research—include methods/type of the study, your variables, and the extent of the work
• Briefly present evidence to support your claim
• Highlight your most important sources

4) Briefly summarize your results

Here you will give an overview of the outcome of your study. Avoid using too many vague qualitative terms (e.g, “very,” “small,” or “tremendous”) and try to use at least some quantitative terms (i.e., percentages, figures, numbers). Save your qualitative language for the conclusion statement. Answer questions like these:

• What did your study yield in concrete terms (e.g., trends, figures, correlation between phenomena)?
• How did your results compare to your hypothesis? Was the study successful?
• Where there any highly unexpected outcomes or were they all largely predicted?

5) State your conclusion

In the last section of your abstract, you will give a statement about the implications and  limitations of the study . Be sure to connect this statement closely to your results and not the area of study in general. Are the results of this study going to shake up the scientific world? Will they impact how people see “Brazilian squirrels”? Or are the implications minor? Try not to boast about your study or present its impact as  too  far-reaching, as researchers and journals will tend to be skeptical of bold claims in scientific papers. Answer one of these questions:

• What are the exact effects of these results on my field? On the wider world?
• What other kind of study would yield further solutions to problems?
• What other information is needed to expand knowledge in this area?

After Completing the First Draft of Your Abstract

Revise your abstract.

The abstract, like any piece of academic writing, should be revised before being considered complete. Check it for  grammatical and spelling errors  and make sure it is formatted properly.

Get feedback from a peer

Getting a fresh set of eyes to review your abstract is a great way to find out whether you’ve summarized your research well. Find a reader who understands research papers but is not an expert in this field or is not affiliated with your study. Ask your reader to summarize what your study is about (including all key points of each section). This should tell you if you have communicated your key points clearly.

In addition to research peers, consider consulting with a professor or even a specialist or generalist writing center consultant about your abstract. Use any resource that helps you see your work from another perspective.

Consider getting professional editing and proofreading

While peer feedback is quite important to ensure the effectiveness of your abstract content, it may be a good idea to find an academic editor  to fix mistakes in grammar, spelling, mechanics, style, or formatting. The presence of basic errors in the abstract may not affect your content, but it might dissuade someone from reading your entire study. Wordvice provides English editing services that both correct objective errors and enhance the readability and impact of your work.

Additional Abstract Rules and Guidelines

Write your abstract after completing your paper.

Although the abstract goes at the beginning of your manuscript, it does not merely introduce your research topic (that is the job of the title), but rather summarizes your entire paper. Writing the abstract last will ensure that it is complete and consistent with the findings and statements in your paper.

Keep your content in the correct order

Both questions and answers should be organized in a standard and familiar way to make the content easier for readers to absorb. Ideally, it should mimic the overall format of your essay and the classic “introduction,” “body,” and “conclusion” form, even if the parts are not neatly divided as such.

Write the abstract from scratch

Because the abstract is a self-contained piece of writing viewed separately from the body of the paper, you should write it separately as well. Never copy and paste direct quotes from the paper and avoid paraphrasing sentences in the paper. Using new vocabulary and phrases will keep your abstract interesting and free of redundancies while conserving space.

Don’t include too many details in the abstract

Again, the density of your abstract makes it incompatible with including specific points other than possibly names or locations. You can make references to terms, but do not explain or define them in the abstract. Try to strike a balance between being specific to your study and presenting a relatively broad overview of your work.

Wordvice Resources

If you think your abstract is fine now but you need input on abstract writing or require English editing services (including paper editing ), then head over to the Wordvice academic resources page, where you will find many more articles, for example on writing the Results , Methods , and Discussion sections of your manuscript, on choosing a title for your paper , or on how to finalize your journal submission with a strong cover letter .

What is an abstract?

What is a "good" abstract, techniques to write an abstract, "abstract checklist" from: how to write a good scientific paper. chris a. mack. spie. 2018..

• INTRODUCTION
• LITERATURE CITED
• Bibliography of guides to scientific writing and presenting
• Peer Review
• Presentations
• Lab Report Writing Guides on the Web

There are as many kinds as abstracts as there are types of research papers.  The classic abstract is usually a "Informative" abstract. This kind of abstract communicates compressed information and include the purpose, methods, and scope of the article. They are usually short (250 words or less) and allow the reader to decide whether they want to read the article.

The goal is to communicate:

• What was done?
• Why was it done?
• How was it done?
• What was found?
• What is the significance of the findings?
• Self contained. Uses 1 or more well developed paragraphs
• Uses introduction/body/conclusion structure
• Presents purpose, results, conclusions and recommendations in that order
• Adds no new information
• Is understandable to a wide audience
• Write the abstract last
• Reread the article looking specifically for the main parts: Purpose, methods, scope, results, conclusions, and recommendations
• Write a first rough draft without looking at the original article
• Edit your draft by correcting organization, improving transitions, dropping unnecessary information and words, and adding important information you left out

The abstract should be a concise (200 words or less), standalone summary of the paper, with 1–2 sentences on each of these topics:

• Background: What issues led to this work? What is the environment that makes this work interesting or important?
• Aim: What were the goals of this work? What gap is being filled?
• Approach: What went into trying to achieve the aims (e.g., experimental method, simulation approach, theoretical approach, combinations of these, etc.)? What was actually done?
• Results: What were the main results of the study (including numbers, if appropriate)?
• Conclusions: What were the main conclusions? Why are the results important? Where will they lead?

The abstract should be written for the audience of this journal: do not assume too much or too little background with the topic.

Ensure that all of the information found in the abstract also can be found in the body of the paper.

Ensure that the important information of the paper is found in the abstract.

Avoid: using the first paragraph of the introduction as an abstract; citations in the abstract; acronyms (but if used, spell them out); referring to figures or tables from the body of the paper; use of the first person; use of words like “new” or “novel,” or phrases like “in this paper,” “we report,” or “will be discussed.”

What this handout is about

This handout provides definitions and examples of the two main types of abstracts: descriptive and informative. It also provides guidelines for constructing an abstract and general tips for you to keep in mind when drafting. Finally, it includes a few examples of abstracts broken down into their component parts.

What is an abstract?

An abstract is a self-contained, short, and powerful statement that describes a larger work. Components vary according to discipline. An abstract of a social science or scientific work may contain the scope, purpose, results, and contents of the work. An abstract of a humanities work may contain the thesis, background, and conclusion of the larger work. An abstract is not a review, nor does it evaluate the work being abstracted. While it contains key words found in the larger work, the abstract is an original document rather than an excerpted passage.

Why write an abstract?

You may write an abstract for various reasons. The two most important are selection and indexing. Abstracts allow readers who may be interested in a longer work to quickly decide whether it is worth their time to read it. Also, many online databases use abstracts to index larger works. Therefore, abstracts should contain keywords and phrases that allow for easy searching.

Say you are beginning a research project on how Brazilian newspapers helped Brazil’s ultra-liberal president Luiz Ignácio da Silva wrest power from the traditional, conservative power base. A good first place to start your research is to search Dissertation Abstracts International for all dissertations that deal with the interaction between newspapers and politics. “Newspapers and politics” returned 569 hits. A more selective search of “newspapers and Brazil” returned 22 hits. That is still a fair number of dissertations. Titles can sometimes help winnow the field, but many titles are not very descriptive. For example, one dissertation is titled “Rhetoric and Riot in Rio de Janeiro.” It is unclear from the title what this dissertation has to do with newspapers in Brazil. One option would be to download or order the entire dissertation on the chance that it might speak specifically to the topic. A better option is to read the abstract. In this case, the abstract reveals the main focus of the dissertation:

This dissertation examines the role of newspaper editors in the political turmoil and strife that characterized late First Empire Rio de Janeiro (1827-1831). Newspaper editors and their journals helped change the political culture of late First Empire Rio de Janeiro by involving the people in the discussion of state. This change in political culture is apparent in Emperor Pedro I’s gradual loss of control over the mechanisms of power. As the newspapers became more numerous and powerful, the Emperor lost his legitimacy in the eyes of the people. To explore the role of the newspapers in the political events of the late First Empire, this dissertation analyzes all available newspapers published in Rio de Janeiro from 1827 to 1831. Newspapers and their editors were leading forces in the effort to remove power from the hands of the ruling elite and place it under the control of the people. In the process, newspapers helped change how politics operated in the constitutional monarchy of Brazil.

From this abstract you now know that although the dissertation has nothing to do with modern Brazilian politics, it does cover the role of newspapers in changing traditional mechanisms of power. After reading the abstract, you can make an informed judgment about whether the dissertation would be worthwhile to read.

Besides selection, the other main purpose of the abstract is for indexing. Most article databases in the online catalog of the library enable you to search abstracts. This allows for quick retrieval by users and limits the extraneous items recalled by a “full-text” search. However, for an abstract to be useful in an online retrieval system, it must incorporate the key terms that a potential researcher would use to search. For example, if you search Dissertation Abstracts International using the keywords “France” “revolution” and “politics,” the search engine would search through all the abstracts in the database that included those three words. Without an abstract, the search engine would be forced to search titles, which, as we have seen, may not be fruitful, or else search the full text. It’s likely that a lot more than 60 dissertations have been written with those three words somewhere in the body of the entire work. By incorporating keywords into the abstract, the author emphasizes the central topics of the work and gives prospective readers enough information to make an informed judgment about the applicability of the work.

When do people write abstracts?

• when submitting articles to journals, especially online journals
• when applying for research grants
• when writing a book proposal
• when completing the Ph.D. dissertation or M.A. thesis
• when writing a proposal for a conference paper
• when writing a proposal for a book chapter

Most often, the author of the entire work (or prospective work) writes the abstract. However, there are professional abstracting services that hire writers to draft abstracts of other people’s work. In a work with multiple authors, the first author usually writes the abstract. Undergraduates are sometimes asked to draft abstracts of books/articles for classmates who have not read the larger work.

Types of abstracts

There are two types of abstracts: descriptive and informative. They have different aims, so as a consequence they have different components and styles. There is also a third type called critical, but it is rarely used. If you want to find out more about writing a critique or a review of a work, see the UNC Writing Center handout on writing a literature review . If you are unsure which type of abstract you should write, ask your instructor (if the abstract is for a class) or read other abstracts in your field or in the journal where you are submitting your article.

Descriptive abstracts

A descriptive abstract indicates the type of information found in the work. It makes no judgments about the work, nor does it provide results or conclusions of the research. It does incorporate key words found in the text and may include the purpose, methods, and scope of the research. Essentially, the descriptive abstract describes the work being abstracted. Some people consider it an outline of the work, rather than a summary. Descriptive abstracts are usually very short—100 words or less.

Informative abstracts

The majority of abstracts are informative. While they still do not critique or evaluate a work, they do more than describe it. A good informative abstract acts as a surrogate for the work itself. That is, the writer presents and explains all the main arguments and the important results and evidence in the complete article/paper/book. An informative abstract includes the information that can be found in a descriptive abstract (purpose, methods, scope) but also includes the results and conclusions of the research and the recommendations of the author. The length varies according to discipline, but an informative abstract is rarely more than 10% of the length of the entire work. In the case of a longer work, it may be much less.

Here are examples of a descriptive and an informative abstract of this handout on abstracts . Descriptive abstract:

The two most common abstract types—descriptive and informative—are described and examples of each are provided.

Informative abstract:

Abstracts present the essential elements of a longer work in a short and powerful statement. The purpose of an abstract is to provide prospective readers the opportunity to judge the relevance of the longer work to their projects. Abstracts also include the key terms found in the longer work and the purpose and methods of the research. Authors abstract various longer works, including book proposals, dissertations, and online journal articles. There are two main types of abstracts: descriptive and informative. A descriptive abstract briefly describes the longer work, while an informative abstract presents all the main arguments and important results. This handout provides examples of various types of abstracts and instructions on how to construct one.

Which type should I use?

Your best bet in this case is to ask your instructor or refer to the instructions provided by the publisher. You can also make a guess based on the length allowed; i.e., 100-120 words = descriptive; 250+ words = informative.

How do I write an abstract?

The format of your abstract will depend on the work being abstracted. An abstract of a scientific research paper will contain elements not found in an abstract of a literature article, and vice versa. However, all abstracts share several mandatory components, and there are also some optional parts that you can decide to include or not. When preparing to draft your abstract, keep the following key process elements in mind:

• Reason for writing: What is the importance of the research? Why would a reader be interested in the larger work?
• Problem: What problem does this work attempt to solve? What is the scope of the project? What is the main argument/thesis/claim?
• Methodology: An abstract of a scientific work may include specific models or approaches used in the larger study. Other abstracts may describe the types of evidence used in the research.
• Results: Again, an abstract of a scientific work may include specific data that indicates the results of the project. Other abstracts may discuss the findings in a more general way.
• Implications: What changes should be implemented as a result of the findings of the work? How does this work add to the body of knowledge on the topic?

(This list of elements is adapted with permission from Philip Koopman, “How to Write an Abstract.” )

All abstracts include:

• A full citation of the source, preceding the abstract.
• The most important information first.
• The same type and style of language found in the original, including technical language.
• Key words and phrases that quickly identify the content and focus of the work.
• Clear, concise, and powerful language.

Abstracts may include:

• The thesis of the work, usually in the first sentence.
• Background information that places the work in the larger body of literature.
• The same chronological structure as the original work.

How not to write an abstract:

• Do not refer extensively to other works.
• Do not add information not contained in the original work.
• Do not define terms.

If you are abstracting your own writing

When abstracting your own work, it may be difficult to condense a piece of writing that you have agonized over for weeks (or months, or even years) into a 250-word statement. There are some tricks that you could use to make it easier, however.

Reverse outlining:

This technique is commonly used when you are having trouble organizing your own writing. The process involves writing down the main idea of each paragraph on a separate piece of paper– see our short video . For the purposes of writing an abstract, try grouping the main ideas of each section of the paper into a single sentence. Practice grouping ideas using webbing or color coding .

For a scientific paper, you may have sections titled Purpose, Methods, Results, and Discussion. Each one of these sections will be longer than one paragraph, but each is grouped around a central idea. Use reverse outlining to discover the central idea in each section and then distill these ideas into one statement.

Cut and paste:

To create a first draft of an abstract of your own work, you can read through the entire paper and cut and paste sentences that capture key passages. This technique is useful for social science research with findings that cannot be encapsulated by neat numbers or concrete results. A well-written humanities draft will have a clear and direct thesis statement and informative topic sentences for paragraphs or sections. Isolate these sentences in a separate document and work on revising them into a unified paragraph.

If you are abstracting someone else’s writing

When abstracting something you have not written, you cannot summarize key ideas just by cutting and pasting. Instead, you must determine what a prospective reader would want to know about the work. There are a few techniques that will help you in this process:

Identify key terms:

Search through the entire document for key terms that identify the purpose, scope, and methods of the work. Pay close attention to the Introduction (or Purpose) and the Conclusion (or Discussion). These sections should contain all the main ideas and key terms in the paper. When writing the abstract, be sure to incorporate the key terms.

Highlight key phrases and sentences:

Instead of cutting and pasting the actual words, try highlighting sentences or phrases that appear to be central to the work. Then, in a separate document, rewrite the sentences and phrases in your own words.

Don’t look back:

After reading the entire work, put it aside and write a paragraph about the work without referring to it. In the first draft, you may not remember all the key terms or the results, but you will remember what the main point of the work was. Remember not to include any information you did not get from the work being abstracted.

Revise, revise, revise

No matter what type of abstract you are writing, or whether you are abstracting your own work or someone else’s, the most important step in writing an abstract is to revise early and often. When revising, delete all extraneous words and incorporate meaningful and powerful words. The idea is to be as clear and complete as possible in the shortest possible amount of space. The Word Count feature of Microsoft Word can help you keep track of how long your abstract is and help you hit your target length.

Example 1: Humanities abstract

Kenneth Tait Andrews, “‘Freedom is a constant struggle’: The dynamics and consequences of the Mississippi Civil Rights Movement, 1960-1984” Ph.D. State University of New York at Stony Brook, 1997 DAI-A 59/02, p. 620, Aug 1998

This dissertation examines the impacts of social movements through a multi-layered study of the Mississippi Civil Rights Movement from its peak in the early 1960s through the early 1980s. By examining this historically important case, I clarify the process by which movements transform social structures and the constraints movements face when they try to do so. The time period studied includes the expansion of voting rights and gains in black political power, the desegregation of public schools and the emergence of white-flight academies, and the rise and fall of federal anti-poverty programs. I use two major research strategies: (1) a quantitative analysis of county-level data and (2) three case studies. Data have been collected from archives, interviews, newspapers, and published reports. This dissertation challenges the argument that movements are inconsequential. Some view federal agencies, courts, political parties, or economic elites as the agents driving institutional change, but typically these groups acted in response to the leverage brought to bear by the civil rights movement. The Mississippi movement attempted to forge independent structures for sustaining challenges to local inequities and injustices. By propelling change in an array of local institutions, movement infrastructures had an enduring legacy in Mississippi.

Now let’s break down this abstract into its component parts to see how the author has distilled his entire dissertation into a ~200 word abstract.

Example 2: Science Abstract

Luis Lehner, “Gravitational radiation from black hole spacetimes” Ph.D. University of Pittsburgh, 1998 DAI-B 59/06, p. 2797, Dec 1998

The problem of detecting gravitational radiation is receiving considerable attention with the construction of new detectors in the United States, Europe, and Japan. The theoretical modeling of the wave forms that would be produced in particular systems will expedite the search for and analysis of detected signals. The characteristic formulation of GR is implemented to obtain an algorithm capable of evolving black holes in 3D asymptotically flat spacetimes. Using compactification techniques, future null infinity is included in the evolved region, which enables the unambiguous calculation of the radiation produced by some compact source. A module to calculate the waveforms is constructed and included in the evolution algorithm. This code is shown to be second-order convergent and to handle highly non-linear spacetimes. In particular, we have shown that the code can handle spacetimes whose radiation is equivalent to a galaxy converting its whole mass into gravitational radiation in one second. We further use the characteristic formulation to treat the region close to the singularity in black hole spacetimes. The code carefully excises a region surrounding the singularity and accurately evolves generic black hole spacetimes with apparently unlimited stability.

This science abstract covers much of the same ground as the humanities one, but it asks slightly different questions.

In academic writing, learning how to create a brief and informative abstract for your research paper is really important. An abstract serves as a sneak peek into your research, giving readers a quick look to decide if they want to read more.

But what exactly is an abstract in a research paper, and how to write an abstract for a research paper that captures the essence of your study effectively? Let’s dive into the nuances of writing a standout research paper abstract!

Improve your paper’s quality with top-notch editing! Get started

Let’s start by understanding what is an abstract in a research paper:

What is an abstract in a research paper?

A research paper abstract is a summary that outlines the key points of your research paper. It serves as a condensed version of your work, allowing readers to quickly grasp the purpose, methodology , results, implications, and conclusion of your study. Think of it as a mini-version of your paper, where you highlight the most critical information to entice further reading.

What is the purpose of an abstract in a research paper?

The primary purpose of an abstract in a research paper is to inform potential readers about the essential contents of the document. It will help them decide whether it aligns with their own research interests or objectives. Also, it’s important because it helps your paper show up in academic databases, making it easier for people to find and read.

Where does the abstract go in a research paper?

Typically, the abstract is placed right after the title page and before the main body of the research paper . This arrangement guarantees that it is the first in-depth synopsis of your work that readers will come across. 

How long should an abstract be for a research paper?

The length of an abstract for a research paper typically ranges from 150 to 250 words. This short length summarizes the research’s main aspects clearly and briefly. Sticking within this word range is important to maintain clarity and brevity so that readers can quickly grasp the important information. You can use academic ChatGPT prompts to reduce your abstract’s length if it exceeds the word count. 

What does the abstract of a research paper contain?

A research paper abstract usually contains the following key elements:

• Purpose of the study: Clearly states the main goal or issue addressed by the research, providing insight into its importance.
• Methodology: Concisely explains the methods or approaches employed in the research, including the type of study conducted (e.g., experimental, observational, qualitative) and specific techniques or tools utilized.
• Results: Summarizes the primary findings or outcomes of the research, highlighting key data points, trends, or discoveries relevant to the research question and objectives.
• Conclusions: Outlines the implications of the findings. This could involve discussing the significance of the results in the context of the field, potential applications, or future research directions. If your study has significant limitations, it’s advisable to briefly note them in the abstract.
• Keywords: Often, research paper abstracts include a list of keywords that help categorize the paper and make it easier for others to find through searches. Select words that are directly related to your research topic. Typically, 5-7 keywords are sufficient. Check the journal’s guidelines for specific requirements.

How to write an abstract for a research paper?

Use the following steps to write your research paper abstract perfectly:

1. Start with clarity and precision

Begin your abstract by clearly stating the research problem or the main objective of the study. This should address the ‘what’ of your study—what was your research trying to find or prove? 

• Avoid vague phrases and focus on delivering a specific and concise statement that encapsulates the essence of your research .
• Use active voice and confident language to state your research aim. For example, instead of saying “This research attempts to explore,” you could say, “This research explores.”
• Ensure that the first one or two sentences encapsulate the critical motivation behind the study.

Poor example: “This paper looks at climate change.”

Improved example: “This study quantifies the impact of industrial emissions on urban air quality, addressing a critical gap in environmental policy formulation.”

• Avoid filler words or overly complex sentences that do not add value to the core understanding of your research.

2. Describe your methodology

Provide a concise overview of the methods you employed for your research. This part should give readers a clear understanding of your approach and techniques. The goal is to provide enough information to understand the foundation of your findings.

• Focus on including only the most crucial methods used in your research. Typically, this would be the overall approach (e.g., qualitative, quantitative, mixed methods), significant techniques or instruments used, and the type of analysis conducted.
• Avoid jargon or overly technical terms that might be unfamiliar to a broader audience, aiming instead for clear, accessible language.
• If specific tools, software, or technologies are central to the results, mention them by name.

Example: “Data was analyzed using SPSS software.”

• Abstracts do not allow for extensive methodological descriptions. Provide enough detail to understand the framework briefly.

For example: Instead of saying, “We conducted several tests to analyze the samples,” specify briefly, “Samples were analyzed using X-ray diffraction and gas chromatography.”

3. Highlight key findings

Briefly summarize the most significant results of your study . Make sure to capture the importance and implications of your results. This part typically grabs the most attention from readers.

• Focus on mentioning quantifiable results if applicable, as these often convey the impact of your findings more powerfully.
• Use phrases that summarize significant trends rather than complex data details. For example, “Results show a 50% increase in efficiency” or “Findings indicate a significant reduction in incidence rates.”
• Use strong, positive adjectives to describe your findings, such as “significant,” “substantial,” “robust,” etc., where appropriate and accurate.
• Include critical statistics such as p-values or confidence intervals to support the significance of your findings.

4. Discuss the implications

In a few sentences, describe the broader implications of your findings. How does your research contribute to the field? What are the practical or theoretical implications?

• Consider questions like, “Why does this matter?” and “Who will benefit from this research?”
• This can be framed as, “These findings suggest new pathways for clinical treatment,” or “This research informs policy by demonstrating…”
• Clearly state how your findings contribute to the existing body of knowledge in your field. Do they extend, contradict, or refine previous theories?

Example: “These findings challenge the conventional understanding of X, suggesting a revised model for Y.”

• Use strong action verbs to describe the effect of your research, such as “transforms,” “enables,” “revolutionizes,” or “underscores.”

5. Keep it concise

Focus on writing within the word limit and keeping the information that is required to be showcased or highlighted. 

• After drafting your abstract, review it specifically for redundancy and verbosity. You can edit your research paper abstract using content editors and grammar checker tools to ensure an error-free research paper abstract.
• Word counter tools like QuillBot, Semrush, Word Count, etc. can help ensure you stay within the typical 150-250 word range. 
• Additionally, asking a colleague to review your abstract format can provide insights into any unnecessary details or unclear wording. Proofreading your research paper abstract is a crucial step.

Research paper abstract example

To solidify your understanding, let’s look at a research paper abstract example:

In this study, we explored the impact of climate change on Arctic marine life. Using a combination of satellite imagery and direct observation methods over five years, we observed a significant decrease in sea ice coverage and its direct effects on the indigenous marine populations. Notably, the reduction in ice has led to altered migration patterns and decreased population stability in polar bears and seals. These findings highlight the urgent need for policies aimed at mitigating the effects of climate change in polar regions.

Creating a strong research paper abstract goes beyond simply summarizing your work. It involves offering a clear, concise, and captivating overview that sparks interest and showcases the significance of your research. By adhering to these tips, you can develop an abstract that meets academic requirements while also engaging your target audience effectively.

How to Write an Abstract for a Research Paper

Writing Informative Abstracts

Informative abstracts state in one paragraph the essence of a whole paper about a study or a research project. That one paragraph must mention all the main points or parts of the paper: a description of the study or project, its methods, the results, and the conclusions. Here is an example of the abstract accompanying a seven-page essay that appeared in 2002 in  The Journal of Clinical Psychology :

The relationship between boredom proneness and health-symptom reporting was examined. Undergraduate students (N = 200) completed the Boredom Proneness Scale and the Hopkins Symptom Checklist. A multiple analysis of covariance indicated that individuals with high boredom-proneness total scores reported significantly higher ratings on all five sub-scales of the Hopkins Symptom Checklist (Obsessive–Compulsive, Somatization, Anxiety, Interpersonal Sensitivity, and Depression). The results suggest that boredom proneness may be an important element to consider when assessing symptom reporting. Implications for determining the effects of boredom proneness on psychological- and physical-health symptoms, as well as the application in clinical settings, are discussed. —Jennifer Sommers and Stephen J. Vodanovich, (adsbygoogle = window.adsbygoogle || []).push({}); “Boredom Proneness”

The first sentence states the nature of the study being reported. The next summarizes the method used to investigate the problem, and the following one gives the results: students who, according to specific tests, are more likely to be bored are also more likely to have certain medical or psychological symptoms. The last two sentences indicate that the paper discusses those results and examines the conclusion and its implications.

Writing Descriptive Abstracts

Descriptive abstracts are usually much briefer than informative abstracts and provide much less information. Rather than summarizing the entire paper, a descriptive abstract functions more as a teaser, providing a quick overview that invites the reader to read the whole. Descriptive abstracts usually do not give or discuss results or set out the conclusion or its implications. A descriptive abstract of the boredom-proneness essay might simply include the first sentence from the informative abstract plus a final sentence of its own:

The relationship between boredom proneness and health-symptom reporting was examined. The findings and their application in clinical settings are discussed.

Writing Proposal Abstracts

Proposal abstracts contain the same basic information as informative abstracts, but their purpose is very different. You prepare proposal abstracts to persuade someone to let you write on a topic, pursue a project, conduct an experiment, or present a paper at a scholarly conference. This kind of abstract is not written to introduce a longer piece but rather to stand alone, and often the abstract is written before the paper itself. Titles and other aspects of the proposal deliberately reflect the theme of the proposed work, and you may use the future tense, rather than the past, to describe work not yet completed. Here is a possible proposal for doing research on boredom:

Undergraduate students will complete the Boredom Proneness Scale and the Hopkins Symptom Checklist. A multiple analysis of covariance will be performed to determine the relationship between boredom-proneness total scores and ratings on the five sub-scales of the Hopkins Symptom Checklist (Obsessive–Compulsive, Somatization, Anxiety, Interpersonal Sensitivity, and Depression).

Key Features of a Research Paper Abstract

• A summary of basic information . An informative abstract includes enough information to substitute for the report itself, a descriptive abstract offers only enough information to let the audience decide whether to read further, and a proposal abstract gives an overview of the planned work.
• Objective description . Abstracts present information on the contents of a report or a proposed study; they do not present arguments about or personal perspectives on those contents. The informative abstract on boredom proneness, for example, offers only a tentative conclusion: “The results suggest that boredom proneness may be an important element to consider.”
• Brevity . Although the length of abstracts may vary, journals and organizations often restrict them to 120–200 words—meaning you must carefully select and edit your words.

A Brief Guide to Writing Abstracts

Consider the rhetorical situation.

• Purpose : Are you giving a brief but thorough overview of a completed study? Only enough information to create interest? Or a proposal for a planned study or presentation?
• Audience : For whom are you writing this abstract? What information about your project will your readers need?
• Stance : Whatever your stance in the longer work, your abstract must be objective.
• Media/Design : How will you set your abstract off from the rest of the text? If you are publishing it online, will you devote a single page to it? What format does your audience require?

Generating Ideas and Text

Write the paper first, the abstract last. You can then use the finished work as the guide for the abstract, which should follow the same basic structure. Exception: You may need to write a proposal abstract months before the work it describes will be complete.

Copy and paste key statements. If you’ve already written the work, highlight your thesis, objective, or purpose; basic information on your methods; your results; and your conclusion. Copy and paste those sentences into a new document to create a rough version of your abstract.

Pare down the information to key ideas. Summarize the report, editing out any nonessential words and details. In your first sentence, introduce the overall scope of your study. Also include any other information that seems crucial to understanding your paper. Avoid phrases that add unnecessary words, such as “It is concluded that.” In general, you probably won’t want to use “I”; an abstract should cover ideas, not say what you think or will do.

Conform to any requirements. In general, an informative abstract should be at most 10 percent as long as the original and no longer than the maximum length allowed. Descriptive abstracts should be shorter still, and proposal abstracts should conform to the requirements of the organization calling for the proposal.

By now your writing is almost complete; you’ve come a long way, but you’re not finished yet! Now it’s time to revise the research paper.

Writing an Abstract

What is an abstract.

An abstract is a summary of your paper and/or research project. It is NOT an introduction to your paper; rather, it should highlight your major points, explain why your work is important, describe how you researched your problem, and offer your conclusions. Typically, an abstract should be approximately 250-300 words. 

How do I prepare an abstract?

Review the components of an abstract.

The exact content of your abstract will depend on the status of your project, disciplinary norms, and feedback from your mentor; however, it should include several of the components listed below: 

• Problem:  What is the central problem or question you investigated? 
• Context: Provide brief background to place your project into context. Explain previous studies, concepts, or theoretical or critical frameworks relevant to your research (i.e., what’s already known or has been done on this topic). 
• Purpose: Outline how your work is contributing to the existing knowledge or is addressing gaps within your field (i.e., why this area of research is important and what’s the rationale for your work). 
• Hypothesis: What prediction(s) did you make based on your research question? 
• Methods: Describe the important methods you used to perform your research or evidence you examined. 
• Results: What are the major results, findings or arguments of the research project?  
• Interpretation: How do your results relate back to your central problem? 
• Implications: Why are your results important? What can we learn from them? 

Understand the structure of an abstract

Once you are familiar with the key components of an abstract, the next step is to understand how to organize these elements effectively. The composition of your abstract can also take different forms depending on the type of research and the conventions of your specific discipline. Below are common structures for projects in STEM fields and in the humanities suggested by The Writing Center . 

For STEM and experimental projects

• Objective/Goal/Significance (Why did you do it or why did it need to be done? Why is this question important/worth asking?) 
• Methods/Approach (What did you do? How did you attempt to answer this question?) 
• Results (What did you find/expect to find? What did the research reveal?) 
• Conclusions (What did you learn?) 

For humanities projects

(Version 1)

• Background (What’s the importance of your topic?) 
• Thesis (What argument or claim are you making?) 
• Theoretical Approach (if applicable) 
• Conclusion 

(Version 2)

• Background (Existing conversation, contribution of research) 

Consider your audience

For the purposes of the symposium, the wording of an abstract should be understandable to a well-read, interdisciplinary audience. Specialized terms should be either defined or avoided.

• How to Write An Abstract For Research Papers: Tips & Examples

In many ways, an abstract is like a trailer of a movie or the synopsis of your favorite book. Its job is to whet the reader’s appetite by sharing important information about your work. After reading a well-written abstract, one should have enough interest to explore the full research thesis. 

So how do you write an interesting abstract that captures the core of your study? First, you need to understand your research objectives and match them with the key results of your study. In this article, we will share some tips for writing an effective abstract, plus samples you can learn from. 

What is an Abstract in Research Writing?

In simple terms, an abstract is a concise write-up that gives an overview of your systematic investigation. According to Grammarly, it is a self-contained summary of a larger work, and it serves as a preview of the bigger document. 

It usually appears at the beginning of your thesis or research paper and helps the reader to have an overview of your work without going into great detail. This means that when someone reads your abstract, it should give them a clear idea of the purpose of your systematic investigation, your problem statement, key results, and any gaps requiring further investigation. 

So how long should your abstract be to capture all of these details? The reality is you don’t need a lot of words to capture key pieces of information in your abstract. Typically, 6–7 sentences made up of 150–250 words should be just right.

What are the Characteristics of a Good Abstract? 

• A good abstract clearly states the aims and objectives of the research.
• It outlines the research methodology for data gathering , processing and analysis. 
• A good abstract summarizes specific research results.
• It states the key conclusions of the systematic investigation.
• It is brief yet straight to the point. 
• A good abstract is unified and coherent. 
• It is easy to understand and devoid of technical jargon. 
• It is written in an unbiased and objective manner. 

What is the Purpose of an Abstract? 

Every abstract has two major purposes. First, it communicates the relevance of your systematic investigation to readers. After reading your abstract, people can determine how relevant your study is to their primary or secondary research purpose. 

The second purpose of an abstract is to communicate your key findings to those who don’t have time to read the whole paper. Research papers typically run into tens of pages so it takes time to read and digest them. To help readers grasp the core ideas in a systematic investigation, it pays to have a well-written abstract that outlines important information concerning your study. 

In all, your abstract should accurately outline the most important information in your research. Many times, it determines whether people would go ahead to read your dissertation. Abstracts are often indexed along with keywords on academic databases, so they make your thesis easily findable.

What are the Sections of an Abstract?

You already know the key pieces of information that your abstract should communicate. These details are broken into six important sections of the abstract which are: 

• The Introduction or Background
• Research Methodology
• Aims and Objectives 
• Limitations

Let’s discuss them in detail. 

• The Introduction or Background 

The introduction or background is the shortest part of your abstract and usually consists of 2–3 sentences. In fact, some researchers write a single sentence as the introduction of their abstract. The whole idea here is to take the reader through the important events leading to your research. 

Understandably, this information may appear difficult to convey in a few sentences. To help out, consider answering these two questions in the background to your study : 

• What is already known about the subject, related to the paper in question? 
• What is not known about the subject (this is the focus of your study)? 

As much as possible, ensure that your abstract’s introduction doesn’t eat into the word count for the other key information. 

• Research Methodology 

This is the section where you spell out any theories and methods adopted for your study. Ideally, you should cover what has been done and how you went about it to achieve the results of your systematic investigation. It is usually the second-longest section in the abstract. 

In the research methodology section, you should also state the type of research you embarked on; that is, qualitative research or quantitative research —this will inform your research methods too. If you’ve conducted quantitative research, your abstract should contain information like the sample size, data collection methods , sampling technique, and duration of your experiment.

In the end, readers are most interested in the results you’ve achieved with your study. This means you should take time to outline every relevant outcome and show how they affect your research population . Typically, the results section should be the longest one in your abstract and nothing should compromise its range and quality. 

An important thing you should do here is spelled out facts and figures about research outcomes. Instead of a vague statement like, “we noticed that response rates differed greatly between high-income and low-income respondents”, try this: “The response rate was higher in high-income respondents than in their low-income counterparts (59% vs 30%, respectively; P

• Conclusion 

Like the introduction, your conclusion should contain a few sentences that wrap up your abstract. Most researchers express a theoretical opinion about the implications of their study, here. 

Your conclusion should contain three important elements: 

• The primary take-home message
• The additional findings of importance
• The perspective 

Although the conclusion of your abstract should be short, it has a great impact on how readers perceive your study. So, take advantage of this section to reiterate the core message in your systematic investigation. Also, make sure any statements here reflect the true outcomes and methods of your research. 

• Limitations 

Chances are you must have faced certain challenges in the course of your research—it could be at the data collection phase or during sampling . Whatever these challenges are, it pays to let your readers know about them, and the impact they had on your study. 

For example, if you had to switch to convenience sampling or snowball sampling due to difficulties in contacting well-suited research participants, you should include this in your abstract. Also, a lack of previous studies in the research area could pose a limitation on your study. Research limitations provide an opportunity to make suggestions for further research. 

Research aims and objectives speak to what you want to achieve with your study. Typically, research aims focus on a project’s long-term outcomes while the objectives focus on the immediate, short-term outcome of the investigation. You may summarize both using a single paragraph comprising a few sentences.

Stating your aims and objectives will give readers a clear idea of the scope, depth, and direction that your research will ultimately take. Readers would measure your research outcomes against stated aims and objectives to know if you achieved the purpose of your study.

Abstract Writing Styles and General Guidelines 

Now that you know the different sections plus information that your abstract should contain, let’s look at how to write an abstract for your research paper.

A common question that comes up is, should I write my abstract first or last? It’s best to write your abstract after you’ve finished working on the research because you have full information to present to your readers. However, you can always create a draft at the beginning of your systematic investigation and fill in the gaps later.  

Does writing an abstract seem like a herculean task? Here are a few tips to help out. 

1. Always create a framework for your abstract 

Before you start writing, take time to develop a detailed outline for your abstract. Break it into sections and sketch the main and supporting points for each section. You can list keywords plus 1–2 sentences that capture your core messaging. 

2. Read Other Abstracts 

Abstracts are one of the most common research documents, and thousands of them have been written in time past. So, before writing yours, try to study a couple of samples from others. You can find lots of dissertation abstract examples in thesis and dissertation databases.

3. Steer Clear of Jargon As Much As Possible 

While writing your abstract, emphasize clarity over style. This means you should communicate in simple terms and avoid unnecessary filler words and ambiguous sentences. Remember, your abstract should be understandable to readers who are not familiar with your topic. 

4. Focus on Your Research

It goes without saying that your abstract should be solely focused on your research and what you’ve discovered. It’s not the time to cite primary and secondary data sources unless this is absolutely necessary. 

This doesn’t mean you should ignore the scholarly background of your work. You might include a sentence or two summarizing the scholarly background to show the relevance of your work to a broader debate, but there’s no need to mention specific publications. 

Going further, here are some abstract writing guidelines from the University of Bergen: 

• An abstract briefly explains the salient aspects of the content. 
• Abstracts should be accurate and succinct, self-contained, and readable.  
• The abstract should paraphrase and summarise rather than quote from the paper.
• Abstracts should relate only to the paper to be presented/assessed.

Types of Abstracts with Examples 

According to the University of Adelaide, there are two major types of abstracts written for research purposes. First, we have informative abstracts and descriptive abstracts. 

1. Informative Abstract  

An informative abstract is the more common type of abstract written for academic research. It highlights the most important aspects of your systematic investigation without going into unnecessary or irrelevant details that the reader might not find useful. 

The length varies according to discipline, but an informative abstract is rarely more than 10% of the length of the entire work. In the case of longer work, it may be much less.

In any informative abstract, you’d touch on information like the purpose, method, scope, results, and conclusion of your study. By now, you’re thinking, “this is the type of abstract we’ve been discussing all along”, and you wouldn’t be far from the truth. 

Advantages of Informative Abstracts

• These abstracts save time for both the researcher and the readers. 
• It’s easy to refer to these abstracts as secondary research sources. 

Disadvantages of Informative Abstracts

• These types of abstracts lack personality.

Example of an Informative Abstract

• Sample Informative Abstract Based on Experimental Work From Colorado State University
• Sample Informative Abstract Based on Non-experimental Work From Colorado State University

2. Descriptive Abstract 

A descriptive abstract reads like a synopsis and focuses on enticing the reader with interesting information. They don’t care as much for data and details, and instead read more like overviews that don’t give too much away. 

You’d find descriptive abstracts in artistic criticism pieces and entertainment research as opposed to scientific investigations. This type of abstract makes no judgments about the work, nor does it provide results or conclusions of the research. They are usually written in 100 words or less. 

Advantages of Descriptive Abstracts

• It gives a very brief overview of the research paper. 
• It is easier to write descriptive abstracts compared to informational abstracts. 

Disadvantages of Descriptive Abstracts

• They are suitable for scientific research. 
• Descriptive abstracts might omit relevant information that deepens your knowledge of the systematic investigation.

Example of Descriptive Abstracts 

• Sample Descriptive Abstract From Colorado State University

FAQs About Writing Abstracts in Research Papers

1. How Long Should an Abstract Be?

A typical abstract should be about six sentences long or less than 150 words. Most universities have specific word count requirements that fall within 150–300 words. 

2. How Do You Start an Abstract Sentence?

There are several ways to start your abstract. Consider the following methods: 

• State a problem or uncertainty
• Make a general statement with the present research action.
• State the purpose or objective of your research
• State a real-world phenomena or a standard practice.

3. Should you cite in an abstract?

While you can refer to information from specific research papers, there’s no need to cite sources in your abstract. Your abstract should focus on your original research, not on the work of others. 

4. What should not be included in an abstract?

An abstract shouldn’t have numeric references, bibliographies, sections, or even footnotes. 

5. Which tense is used in writing an abstract?

An abstract should be written in the third-person present tense. Use the simple past tense when describing your methodology and specific findings from your study. 

Writing an abstract might appear challenging but with these steps, you should get it right. The easiest approach to writing a good abstract is centering it on key information including your research problem and objectives, methodology, and key results.

How To Write an Abstract (With Examples)

• Smodin Editorial Team
• Updated: August 13, 2024
• Step-by-Step Instructions for Writing

The abstract is the shop front of your thesis. It’s essentially a summary of your paper outlining what you have discovered during your research.

In academia, an abstract serves several purposes:

• Offers a summary of your findings
• Other researchers use it to determine whether your work is relevant to their own research
• Helps your peers understand what you have discovered if they don’t have time to read the entire paper
• Provides an easy way to index and categorize papers for academic journals

So a good abstract has several benefits for readers and reviewers. But, beyond that, you need to know how to write a good abstract if you want to get a high grade.

In our article, we give you some of the best tips and tricks on how to write an abstract that is concise and informative.

Step 1 – Understand the Purpose of an Abstract

Before you learn how to write an abstract, you need to know what one is and what purpose it serves. A good abstract should answer these questions:

• What is the study about?
• Why did you do this study or project?
• What did you do and how?
• What were your findings?
• What do your findings mean?

Think of an abstract like a movie trailer. It gives the reader a glimpse–a teaser–of what’s to come. It helps them decide if your paper is something they’re interested in.

Usually, an abstract is 100-250 words, so you only have a small window to rope your audience in.

There are four types of abstracts. You might use a different one depending on the nature of your research paper . The different kinds of abstracts include:

• Informative abstract: Details the background information, key points, research methods, and significant findings. There may also be further reading recommendations so that the reader can understand the main elements of the paper better.
• Descriptive abstract: Provides an overview of the content, including major points and research methods. However, descriptive abstracts don’t provide significant findings or conclusions. So, they’re less helpful for determining the relevance of the work.
• Critical abstract: Evaluates or provides analysis regarding the paper’s findings, with an overview of the paper. These abstracts are longer, sometimes up to 500 words in length. They may also refer to outside information.
• Highlight abstract: Grabs the reader’s attention to hook them in. Academic writing doesn’t usually include this type of abstract, since it doesn’t really give an overview of the text.

Typically, you’ll only see the first two in academia, but a descriptive abstract is still rarer than an informative one. An informative abstract includes everything you need to know about a research paper. So, it’s the preferred method for most students.

Step 2 – Key Elements of an Abstract

Every good abstract page has certain elements, including the background, methodology, results, and conclusion. It may also include keywords listed at the end of the abstract, helping to categorize and index the paper.

Here’s everything you need to include in your abstract.

Background and Objective

The first part of the abstract should cover the background information for your central idea. Whether you’re studying social sciences or writing a scientific paper, this section is absolutely crucial. It’s the opening line that sets the tone for your entire dissertation.

You can usually do this in around three sentences. Here is what each one should include:

• Sentence 1: Introduce the topic and define the key concepts in your study.
• Sentence 2: Define the gap in the literature, describing the main existing theories and identifying their limitations.
• Sentence 3: Explain how your research will fill this gap in the knowledge and what it adds to your field.

You can also state your research question at this point. Of course, you’ll need to do a literature review to write this effectively. So, check out other abstracts and ensure you use a good sentence structure .

Example: “Climate change poses significant challenges for worldwide agricultural productivity. Despite the numerous studies that exist on its impact on crop yields, there is a lack of comprehensive analysis. Other articles do not study how these impacts vary across different climactic regions. This study aims to fill this gap by examining the regional differences in climate change effects on wheat production.”

Methodology

Next, you can outline the specific details of your project, summarizing the methodology you intend to use. At this point, you can also outline the data, theories, and case studies that you used during your research.

Generally, this can be just a single sentence highlighting your methodology. However, it can vary greatly depending on your field. For example, in scientific writing, you might need to describe the materials you’re using in the study. Meanwhile, for social sciences, it’s likely to be more theory-based.

Example: “I conducted a meta-analysis of existing studies on wheat production under varying climatic conditions. I collected data from peer-reviewed journals published between 2000 and 2023. I used statistical methods to assess the impact of temperature and precipitation changes on wheat yield.”

The next part of your abstract should state your main point. Remember, the abstract is just a brief summary, so you don’t need to go into detail. Instead, summarize all the main arguments that your paper makes and state their contribution to the field.

Even if you feel like your main findings are significant, don’t go into too much detail yet! That comes later, in the paper itself.

Example: “The results indicated a significant negative correlation between increased temperatures and wheat yields in arid and semi-arid regions. The average yield reduction was 15%. Conversely, in temperate regions, moderate temperature increases were associated with a slight yield increase of 5%. Precipitation changes had less consistent effects across different regions.”

The final part of your abstract should provide a strong conclusion. Here, you can discuss the implications of your main findings. Often, you can also incorporate key words found within the abstract and write these in a list at the end. This makes your paper easier to index.

Example: “These findings suggest that climate change adaptation strategies for wheat production must be region-specific. In arid regions, efforts must focus on heat-resistant crop varieties and improving irrigation. Meanwhile, temperate regions may benefit from optimizing planting dates and crop management.

Keywords: Climate change, wheat production, regional analysis, agricultural adaptation, crop yield.”

Step 3 – Writing the Abstract

Now that you understand what an abstract is, you can master the art of writing one. Here are Smodin’s top tips when writing an abstract.

Write a Draft

Start by writing a draft, and don’t put too much emphasis on it being perfect. Make sure your draft includes all the key elements (background, methods, results, conclusions).

Ensure that your draft provides a clear and concise summary of your research, outlining your major findings.

Revise for Clarity and Conciseness

Once you have a draft, you can start to edit and improve it. At this point, you can start to pay more attention to the word count. It’s time to cut out the unnecessary parts and improve clarity.

You should focus on making your abstract as succinct as possible while retaining the essential information. Remember, the abstract is just one paragraph, so you might need to be quite harsh in cutting bits out.

Check for Accuracy and Consistency

Finally, check for accuracy. You’ll need to ensure that the abstract accurately reflects the main ideas in the paper. Don’t mention anything you haven’t talked about in the paper!

You should also check that all the terminology and data are correct. Getting this wrong isn’t just unprofessional, but it could lose you marks!

Step 4 – Formatting the Abstract

Depending on where you’re submitting your paper, there may be a publication manual. This is certainly the case if you’re submitting a journal article. However, your college or university might also have guidelines that they use to standardize abstracts.

It’s important to follow the format that the journal or institution provides. This includes sticking to the word count (decrease or i ncrease the number of words if necessary) but also following the specific format. For example, many journals in the social sciences, natural sciences, and engineering sciences use the IMRaD structure:

• Introduction

Tips for Writing a Compelling Abstract

Want to know how to write an amazing abstract? Not just a good one, but one that’s going to get you the best grade? Here are five tips that will guarantee success.

• Be concise: It’s crucial to be brief. Potential readers don’t want to know all the details just yet. Remember, it’s only a paragraph long! Make sure you use clear and straightforward language throughout.
• Highlight key points: Your abstract should describe the main findings of your abstract, including a range of key phrases. Emphasize these aspects, and ensure that readers understand the significance of the study.
• Avoid jargon: The abstract should be accessible to a broad audience. So, minimize the use of technical terms and acronyms.
• Focus on the reader: It’s important to focus on things that the reader needs to know. The abstract should help them understand the research that comes later. Try to spark their interest without providing too much information.

An abstract is a crisp, short, powerful, and self-contained summary of a research manuscript used to help the reader swiftly determine the paper’s purpose. Although the abstract is the first paragraph of the manuscript it should be written last when all the other sections have been addressed.

Research is formalized curiosity. It is poking and prying with a purpose. — Zora Neale Hurston, American Author, Anthropologist and Filmmaker (1891–1960)

Abstract and Keywords

Additional Commentaries

1 what is an abstract.

An abstract is usually a standalone document that informs the reader about the details of the manuscript to follow. It is like a trailer to a movie, if the trailer is good, it stimulates the audience to watch the movie. The abstract should be written from scratch and not ‘cut –and-pasted’ [ 1 ].

2 What is the History of the Abstract?

An abstract, in the form of a single paragraph, was first published in the Canadian Medical Association Journal in 1960 with the idea that the readers may not have enough time to go through the whole paper, and the first abstract with a defined structure was published in 1991 [ 2 ]. The idea sold and now most original articles and reviews are required to have a structured abstract. The abstract attracts the reader to read the full manuscript [ 3 ].

3 What are the Qualities of a Good Abstract?

The quality of information in an abstract can be summarized by four ‘C’s. It should be:

C: Condensed

C: Critical

4 What are the Types of Abstract?

Before writing the abstract, you need to check with the journal website about which type of abstract it requires, with its length and style in the ‘Instructions to Authors’ section.

The abstract types can be divided into:

Descriptive: Usually written for psychology, social science, and humanities papers. It is about 50–100 words long. No conclusions can be drawn from this abstract as it describes the major points in the paper.

Informative: The majority of abstracts for science-related manuscripts are informative and are surrogates for the research done. They are single paragraphs that provide the reader an overview of the research paper and are about 100–150 words in length. Conclusions can be drawn from the abstracts and in the recommendations written in the last line.

Critical: This type of abstract is lengthy and about 400–500 words. In this, the authors’ own research is discussed for reliability, judgement, and validation. A comparison is also made with similar studies done earlier.

Highlighting: This is rarely used in scientific writing. The style of the abstract is to attract more readers. It is not a balanced or complete overview of the article with which it is published.

Structured: A structured abstract contains information under subheadings like background, aims, material and methods, results, conclusion, and recommendations (Fig. 15.1 ). Most leading journals now carry these.

Example of a structured abstract (with permission editor CMRP)

5 What is the Purpose of an Abstract?

An abstract is written to educate the reader about the study that follows and provide an overview of the science behind it. If written well it also attracts more readers to the article. It also helps the article getting indexed. The fate of a paper both before and after publication often depends upon its abstract. Most readers decide if a paper is worth reading on the basis of the abstract. Additionally, the selection of papers in systematic reviews is often dependent upon the abstract.

6 What are the Steps of Writing an Abstract?

An abstract should be written last after all the other sections of an article have been addressed. A poor abstract may turn off the reader and they may cause indexing errors as well. The abstract should state the purpose of the study, the methodology used, and summarize the results and important conclusions. It is usually written in the IMRAD format and is called a structured abstract [ 4 , 5 ].

I: The introduction in the opening line should state the problem you are addressing.

M: Methodology—what method was chosen to finish the experiment?

R: Results—state the important findings of your study.

D: Discussion—discuss why your study is important.

Mention the following information:

Important results with the statistical information ( p values, confidence intervals, standard/mean deviation).

Arrange all information in a chronological order.

Do not repeat any information.

The last line should state the recommendations from your study.

The abstract should be written in the past tense.

7 What are the Things to Be Avoided While Writing an Abstract?

Cut and paste information from the main text

Hold back important information

Use abbreviations

Tables or Figures

Generalized statements

Arguments about the study

8 What are Key Words?

These are important words that are repeated throughout the manuscript and which help in the indexing of a paper. Depending upon the journal 3–10 key words may be required which are indexed with the help of MESH (Medical Subject Heading).

9 How is an Abstract Written for a Conference Different from a Journal Paper?

The basic concept for writing abstracts is the same. However, in a conference abstract occasionally a table or figure is allowed. A word limit is important in both of them. Many of the abstracts which are presented in conferences are never published in fact one study found that only 27% of the abstracts presented in conferences were published in the next five years [ 6 ].

Table 15.1 gives a template for writing an abstract.

10 What are the Important Recommendations of the International Committees of Medical Journal of Editors?

The recommendations are [ 7 ]:

An abstract is required for original articles, metanalysis, and systematic reviews.

A structured abstract is preferred.

The abstract should mention the purpose of the scientific study, how the procedure was carried out, the analysis used, and principal conclusion.

Clinical trials should be reported according to the CONSORT guidelines.

The trials should also mention the funding and the trial number.

The abstract should be accurate as many readers have access only to the abstract.

11 Conclusions

An Abstract should be written last after all the other sections of the manuscript have been completed and with due care and attention to the details.

It should be structured and written in the IMRAD format.

For many readers, the abstract attracts them to go through the complete content of the article.

The abstract is usually followed by key words that help to index the paper.

How to Write an Abstract - Steps with Examples

Writing reports, papers, and assignments is a significant part of college life, and it often involves complex writing and analysis. One of the most challenging aspects can be crafting an effective abstract. After completing your report, summarizing it concisely can seem daunting. In this guide, I’ll walk you through how to write an abstract for paper that clearly and effectively summarizes your work, making it easier for your readers to grasp the main points.

What to Include & How to Structure Your Abstract?

A.what to include.

An abstract serves as a concise summary of a research paper, providing readers with a quick overview of its essential aspects. It typically begins by setting the context and significance of the research, outlining the broader field and specific topic under study. Central to the abstract is a clear articulation of the research question or problem that the study addresses, emphasizing its relevance and importance within the discipline. Building upon existing literature, the abstract succinctly summarizes previous research while highlighting gaps or limitations that motivate the current study.

Context or Background: Briefly introduce the general and specific topics of your research.

Central Question or Problem: Clearly state the research question or problem addressed.

Previous Research: Summarize what is already known and highlight gaps or limitations.

Methods: Outline the research or analytical methods used.

Findings: Present the main findings or arguments.

Significance: Explain the implications or significance of your findings.

B.How to Structure

Introduction:

Begin with a sentence that sets the context and importance of your research topic.

Briefly mention the specific aspect of the topic that your paper focuses on.

Provide a concise summary of the methods used in your study.

Mention any unique approaches or innovations in your methodology.

Summarize the most significant findings of your research.

Highlight any unexpected results or patterns observed.

Conclusion:

Conclude with the significance of your findings.

Discuss how your research contributes to the field and suggest areas for future study.

C.Things to Avoid

Citing References: Avoid including citations or detailed literature reviews.

Detailed Explanations: Keep descriptions of methods and data concise.

Jargon and Technical Language: Use clear and accessible language to ensure understanding

Types of Abstract

There are two primary types of abstracts: descriptive and informative.

1.Descriptive Abstract:

A descriptive abstract provides a brief overview of the purpose and scope of the research without delving into specific details of findings or conclusions. It aims to give readers a snapshot of what the paper is about.

An example of a descriptive abstract would be where in a study analyzing economic homogamy among spouses, a descriptive abstract might introduce the topic and outline the general findings about increasing economic resemblance between partners without specifying the detailed methods or specific results.

2.Informative Abstract:

An informative abstract offers a comprehensive summary of the entire research paper, including the purpose, methods, results, and conclusions. It provides readers with a clear understanding of the study's objectives and outcomes.

For instance, in a research paper on reprogramming fibroblasts into induced cardiac progenitor cells, an informative abstract would detail the methods used (such as specific gene factors and signaling pathways), summarize the main findings (including the types of cells generated and their potential applications), and discuss the broader implications for cardiac regenerative therapy.

Both types of abstracts serve distinct purposes: descriptive abstracts give a broad overview suitable for quickly understanding the topic, while informative abstracts provide detailed insights into the research, making them ideal for readers seeking in-depth knowledge without reading the full paper.

How to Write an Abstract for paper in 4 Steps [With Examples]

Now that we know an abstract is simply a concise summary of our entire research, the next step is to learn how to write an abstract for a research paper. Remember, the structure of an abstract needs to be followed strictly, and it should be within 300 words to ensure it is impactful and fulfills its purpose. The structure includes:

Problem Statement (1-2 sentences)

Methodology (1-2 sentences)

Results (2-3 sentences)

Significance (1-2 sentences)

With this structure in mind, I will be writing an abstract on the topic 'Ethical Implications of Facial Recognition Technology in Public Surveillance'. To assist me, I will be using WPS Writer as my writing tool because it not only provides me with the necessary editing tools for writing my research paper but also utilizes WPS AI to save time and enhance the meaning of my abstract.

Problem Statement

So first of all, in an abstract, we have the Problem Statement. A problem statement, or research gap, serves as a concise description of the issue or challenge addressed in the research. Students and researchers often end up writing line after line when discussing the research gap, although just 1-2 lines will suffice.

Let's take a look at the draft I have written for the problem statement on WPS Writer.

To shorten this problem statement effectively while ensuring it describes the issue concisely, I'll use WPS AI for assistance. Here's how:

Step 1: Highlight the problem statement using your mouse.

Step 2: After highlighting the text, you will see a floating menu with quick edit tools. Click on the "WPS AI" icon.

Step 3: Upon clicking the WPS AI icon, a list of WPS AI options will appear. Select "Make Shorter".

Step 4: WPS AI will process the text, and once shortened, review it. If satisfactory, click “Replace”; otherwise, opt for “Rewrite” to refine further.

Step 5: With the problem statement shortened, I'll add a human touch by making final adjustments before moving to the next part of our abstract.

Methodology

Next up, we need to discuss the methods used during our research. This includes outlining the specific techniques, procedures, or approaches employed to gather data and analyze findings, ensuring transparency and replicability in scholarly work.

And now, with the help of WPS AI, I'll be shortening my methodology statement to make it more concise and fit my abstract.

Ensure to review any changes made because WPS AI is a writing assistant designed to help you write better, but reviewing is critical to ensure the end result meets your expectations.

After discussing the methodology, we present the results of our research. This section summarizes the key findings and outcomes obtained through the applied methods, providing a clear picture of what was discovered or achieved.

Similar to other sections, I have created a rough draft of my research findings, which I believe are important to include in my abstract.

Now with the assistance of WPS AI, I can further condense my draft. Remember, results can be a bit longer compared to other sections of our abstract, so I'll aim for 2-3 sentences to maintain relevance.

Significance

Finally, we need to discuss the significance of our research and its contributions to the field. This involves explaining how our findings will impact the topic of research and provide a foundation for future studies.

With my significance statement further shortened using WPS AI, I now have my complete abstract statement totaling over 220 words, providing a brief overview of my entire research.

Once you have completed writing your abstract, the next step is to include keywords—a crucial element in learning how to write an abstract for a project or research paper in APA style. When publishing your paper, it's essential to include these keywords at the end of the abstract.

They should highlight important aspects of your research, aiding readers in finding your paper during literature searches. APA Style guidelines specify the formatting rules for these keywords, ensuring consistency and clarity in scholarly publications.

Place keywords directly below the abstract.

Indent the first line of keywords by 0.5 inches.

Use an italicized heading for "Keywords:"

Separate each keyword with a comma and maintain standard font style for keywords.

Remember, the abstract is written once the entire research paper has been completed, so it is the final step before you submit your research paper for publication or to your college professor.

When inputting keywords, think from a reader's perspective about what they are searching for, and include those search terms as your keywords.

While writing your abstract, remember that your research findings are already completed, so the abstract is always in the present or past simple tense.

Avoid delving deeply into the problem when describing your problem statement.

Use verbs like "investigate, test, analyze, evaluate, calculate" to describe the purpose of your research.

In the results section, highlight the most important findings because sometimes research findings are extensive and it might leave you confused about which ones to include.

Mention any limitations encountered during your research.

Glucagon-like peptide 1 (GLP-1) agonists are medications approved for treatment of diabetes that recently have also been used off label for weight loss. 1 Studies have found increased risks of gastrointestinal adverse events (biliary disease, 2 pancreatitis, 3 bowel obstruction, 4 and gastroparesis 5 ) in patients with diabetes. 2 - 5 Because such patients have higher baseline risk for gastrointestinal adverse events, risk in patients taking these drugs for other indications may differ. Randomized trials examining efficacy of GLP-1 agonists for weight loss were not designed to capture these events 2 due to small sample sizes and short follow-up. We examined gastrointestinal adverse events associated with GLP-1 agonists used for weight loss in a clinical setting.

We used a random sample of 16 million patients (2006-2020) from the PharMetrics Plus for Academics database (IQVIA), a large health claims database that captures 93% of all outpatient prescriptions and physician diagnoses in the US through the International Classification of Diseases, Ninth Revision (ICD-9) or ICD-10. In our cohort study, we included new users of semaglutide or liraglutide, 2 main GLP-1 agonists, and the active comparator bupropion-naltrexone, a weight loss agent unrelated to GLP-1 agonists. Because semaglutide was marketed for weight loss after the study period (2021), we ensured all GLP-1 agonist and bupropion-naltrexone users had an obesity code in the 90 days prior or up to 30 days after cohort entry, excluding those with a diabetes or antidiabetic drug code.

Patients were observed from first prescription of a study drug to first mutually exclusive incidence (defined as first ICD-9 or ICD-10 code) of biliary disease (including cholecystitis, cholelithiasis, and choledocholithiasis), pancreatitis (including gallstone pancreatitis), bowel obstruction, or gastroparesis (defined as use of a code or a promotility agent). They were followed up to the end of the study period (June 2020) or censored during a switch. Hazard ratios (HRs) from a Cox model were adjusted for age, sex, alcohol use, smoking, hyperlipidemia, abdominal surgery in the previous 30 days, and geographic location, which were identified as common cause variables or risk factors. 6 Two sensitivity analyses were undertaken, one excluding hyperlipidemia (because more semaglutide users had hyperlipidemia) and another including patients without diabetes regardless of having an obesity code. Due to absence of data on body mass index (BMI), the E-value was used to examine how strong unmeasured confounding would need to be to negate observed results, with E-value HRs of at least 2 indicating BMI is unlikely to change study results. Statistical significance was defined as 2-sided 95% CI that did not cross 1. Analyses were performed using SAS version 9.4. Ethics approval was obtained by the University of British Columbia’s clinical research ethics board with a waiver of informed consent.

Our cohort included 4144 liraglutide, 613 semaglutide, and 654 bupropion-naltrexone users. Incidence rates for the 4 outcomes were elevated among GLP-1 agonists compared with bupropion-naltrexone users ( Table 1 ). For example, incidence of biliary disease (per 1000 person-years) was 11.7 for semaglutide, 18.6 for liraglutide, and 12.6 for bupropion-naltrexone and 4.6, 7.9, and 1.0, respectively, for pancreatitis.

Use of GLP-1 agonists compared with bupropion-naltrexone was associated with increased risk of pancreatitis (adjusted HR, 9.09 [95% CI, 1.25-66.00]), bowel obstruction (HR, 4.22 [95% CI, 1.02-17.40]), and gastroparesis (HR, 3.67 [95% CI, 1.15-11.90) but not biliary disease (HR, 1.50 [95% CI, 0.89-2.53]). Exclusion of hyperlipidemia from the analysis did not change the results ( Table 2 ). Inclusion of GLP-1 agonists regardless of history of obesity reduced HRs and narrowed CIs but did not change the significance of the results ( Table 2 ). E-value HRs did not suggest potential confounding by BMI.

This study found that use of GLP-1 agonists for weight loss compared with use of bupropion-naltrexone was associated with increased risk of pancreatitis, gastroparesis, and bowel obstruction but not biliary disease.

Given the wide use of these drugs, these adverse events, although rare, must be considered by patients who are contemplating using the drugs for weight loss because the risk-benefit calculus for this group might differ from that of those who use them for diabetes. Limitations include that although all GLP-1 agonist users had a record for obesity without diabetes, whether GLP-1 agonists were all used for weight loss is uncertain.
