  1. Longitudinal Study

    Revised on June 22, 2023. In a longitudinal study, researchers repeatedly examine the same individuals to detect any changes that might occur over a period of time. Longitudinal studies are a type of correlational research in which researchers observe and collect data on a number of variables without trying to influence those variables.

    important longitudinal research features long-term studies of many different aspects of development in well-defined populations (e.g., studies of large birth cohorts in Norway, Finland, Sweden, New Zealand, the UK). Other longitudinal studies are focused on particular study questions in community or high-risk samples. We sought to conduct a ...

  3. Longitudinal Study Design: Definition & Examples

    Panel Study. A panel study is a type of longitudinal study design in which the same set of participants are measured repeatedly over time. Data is gathered on the same variables of interest at each time point using consistent methods. This allows studying continuity and changes within individuals over time on the key measured constructs.

  4. Longitudinal Study: Overview, Examples & Benefits

    A longitudinal study is an experimental design that takes repeated measurements of the same subjects over time. These studies can span years or even decades. Unlike cross-sectional studies, which analyze data at a single point, longitudinal studies track changes and developments, producing a more dynamic assessment.

  6. What Is A Longitudinal Study? A Simple Definition

    A longitudinal study or a longitudinal survey (both of which make up longitudinal research) is a study where the same data are collected more than once, at different points in time. The purpose of a longitudinal study is to assess not just what the data reveal at a fixed point in time, but to understand how (and why) things change over time.

  8. Longitudinal Study

    Many governments or research centres carry out longitudinal studies and make the data freely available to the general public. For example, anyone can access data from the 1970 British Cohort Study, which has followed the lives of 17,000 Brits since their births in a single week in 1970, through the UK Data Service website .

  9. Longitudinal study: design, measures, and classic example

    Benefits. Longitudinal studies enable researchers to identify events and relate them to specific exposures. In turn, these exposures can be further defined in terms of presence, timing, and chronicity. 1 In addition, the sequence of events can be established, and change can be followed over time for specific individuals inside the cohort. If a prospective study is undertaken, recall bias can ...

  10. Longitudinal study: design, measures, classic example

    As the name implies, longitudinal studies follow subjects over time (Fig. 42.1).There are three main types of studies that fall under the umbrella of the longitudinal study: cohort studies, panel studies, and retrospective studies. 1 The cohort study is one of the most common types of longitudinal studies. It involves following a cohort (a group of individuals with a shared characteristic(s ...

  11. Longitudinal study: Design, measures, and classic example

    A longitudinal study is a study that repeatedly measures observations (collects data) over time. 1 It often involves following up with patients for a prolonged period, such as years, and measuring both explanatory and outcome variables at multiple points, usually more than two, of follow-up. 2 Longitudinal studies are most commonly ...

  13. Designing and managing longitudinal studies.

    Longitudinal research is essential for understanding how psychopathology and psychological processes unfold over time—but it is an inherently risky endeavor. Longitudinal research requires considerable amounts of time and effort for an uncertain return. The inevitable lag between the start of a longitudinal study and the point when results are ready for publication means there should be ...

  14. Longitudinal studies

    The Framingham study is widely recognised as the quintessential longitudinal study in the history of medical research. An original cohort of 5,209 subjects from Framingham, Massachusetts between the ages of 30 and 62 years of age was recruited and followed up for 20 years.

  15. Longitudinal study

    A longitudinal study (or longitudinal survey, or panel study) is a research design that involves repeated observations of the same variables (e.g., people) over long periods of time (i.e., uses longitudinal data).It is often a type of observational study, although it can also be structured as longitudinal randomized experiment.. Longitudinal studies are often used in social-personality and ...

  16. Developing a Methodological Research Program for Longitudinal Studies

    One of the strategic objectives of the National Institute on Aging (NIA) is to "support the development of population-based data sets, especially from longitudinal studies, suitable for analysis of biological, behavioral, and social factors affecting health, well-being, and functional status through the life course." To contribute to that objective and to inform the development of a ...

  19. Qualitative longitudinal research in health research: a method study

    Qualitative longitudinal research (QLR) comprises qualitative studies, with repeated data collection, that focus on the temporality (e.g., time and change) of a phenomenon. The use of QLR is increasing in health research since many topics within health involve change (e.g., progressive illness, rehabilitation). A method study can provide an insightful understanding of the use, trends and ...
