What are the disadvantages of cross sectional studies?
As cross-sectional studies measure prevalent rather than incident cases, the data will always reflect determinants of survival as well as aetiology1. Unable to measure incidence. Associations identified may be difficult to interpret. Susceptible to bias due to low response and misclassification due to recall bias.
What are the strengths and weaknesses of longitudinal studies?
List of Advantages of Longitudinal Studies
- They are effective in determining variable patterns over time.
- They can ensure clear focus and validity.
- They are very effective in doing research on developmental trends.
- They are more powerful than cross-sectional studies.
- They are highly flexible.
What is a weakness of a longitudinal study?
The key advantage to longitudinal studies is the ability to show the patterns of a variable over time. Another weakness is that while longitudinal data is being collected at multiple points, those observation periods are pre-determined and cannot take into account whatever has happened in between those touch points.
What is the greatest drawback of the longitudinal method?
Longitudinal studies require enormous amounts of time and are often quite expensive. Because of this, these studies often have only a small group of subjects, which makes it difficult to apply the results to a larger population.
