Advantages and disadvantages of a longitudinal case study

Advantages of Disadvantages of Longitudinal Studies

The key feature of panel studies is that they collect repeated measures from the same sample at different points in time. Most panel studies are designed for quantitative analysis and use structured survey data. Panel studies can also use qualitative methods for the data collection and analysis. They may also be constructed from register data, an approach that is common in some countries.

This entry concentrates on household panels collected by surveys.

  • New eligibility for sample inclusion could occur between waves in the following ways;
  • Several types of data may be regarded as longitudinal:

Cross-sectional surveys are based on a sample of the population of interest drawn at one time point. In contrast, panel surveys follow the population of interest over an extended time period and are concerned with measuring change over time for the units of analysis within the population.

Examine the disadvantages of longitudinal studies

The unit of analysis is typically an individual, but it could also be a firm or a dwelling or any other unit of analysis required by the research design.

Panel surveys typically collect data at relatively frequent intervals depending on the design requirements of a given study. Some run over many years and others are short term, such as short panels conducted around elections. Panel surveys are distinct from cohort studies, which often sample an age cohort born in a particular month and year and follow that cohort at infrequent intervals, often with a focus on early childhood development.

  1. This type of study is unique and has an advantage over other research options.
  2. Because several types of data may be regarded as longitudinal, methods for the analysis of social change may also vary substantially. Advantages of Longitudinal Studies There are a few benefits that can only be gained by using a longitudinal study.
  3. Handbook of longitudinal research.
  4. Strictly speaking, longitudinal studies are limited to prospective studies, while retrospective studies have been defined as a quasi-longitudinal design, since they do not offer the same strengths for research on causal processes Hakim 1987.
  5. Cross-sectional surveys are based on a sample of the population of interest drawn at one time point.

While the difference between cohort and panel designs can be overstated, panel studies typically sample from the entire age range and collect repeated measures across the age range and throughout the life course. Panel studies have been used extensively to monitor the dynamics of poverty, movements into and out of the labor market, and the process of demographic change.

Longitudinal data generated from panel studies can be analyzed to understand the short-term dynamics of change, including movements into and out of employment or transitions into and out of poverty.

General Overviews The works in this section provide a combination of overviews to survey methods and longitudinal studies in general, as well as panel studies in particular. They provide an introduction to the range of issues to be considered when designing, implementing, and analyzing longitudinal data sets, which tend to be more complex than surveys done in a cross-sectional context.

The principles of high-quality data collection that apply to cross-sectional surveys also apply to longitudinal surveys, but there are additional issues to consider due to the longitudinal design.

Rose 2000 and Ruspini 2002 introduce the principles that apply to high-quality data collection for panel studies and are accessible introductions for those unfamiliar with how panel data can be used in analysis.

They provide helpful examples of research using panel data to illustrate how these data can be exploited in analysis.

The first major volume to synthesize the complexities involved in designing and managing a panel study was Kasprzyk, et al. Menard 2008 and Lynn 2009 are up-to-date edited volumes, with contributions by experts in the field, on the methodology of longitudinal surveys, including new developments in the field.

They highlight the advantages and disadvantages of panel studies for analysis, statistical adjustments such as weighting and imputation, and panel data analysis techniques. Surveys in social research.

  • However, the world of longitudinal research is quite heterogeneous;
  • It is therefore common for cross-sectional data to be recorded in a succession of surveys at two or more points in time, with a new sample on each occasion.

  1. Because longitudinal research is a broad term, methods for the analysis of social change may also vary substantially.
  2. When data are recorded in a continuous time, the number and sequence of events and the duration between them can all be calculated. To return to our example, we might choose to look at the change in cholesterol levels among women over 40 who walk daily for a period of 20 years.
  3. In contrast, panel surveys follow the population of interest over an extended time period and are concerned with measuring change over time for the units of analysis within the population.
  4. These studies are high in validity and are great for picking up long-term changes. The first approach is typical of a cross-sectional study.
  5. Cross-sectional studies can be done more quickly than longitudinal studies. This is because such studies offer a snapshot of a single moment in time; they do not consider what happens before or after the snapshot is taken.
