Answer :
The type of research design that compares various participants at several points in time to examine age-related differences and changes is called a longitudinal study design.
- A longitudinal study is an observational one, just like a cross-sectional one.
- So once more, researchers respect their subjects' privacy.
- In contrast, researchers observe the same subjects repeatedly during the course of a longitudinal study, which can run for years at a time.
- One well-known example of a longitudinal study is the 1970 British Cohort Study, which has gathered information on the lives of 17,000 Britons since their births in 1970.
- There can also be effects on the study data collected due to the repeated testing of participants.
- The only caveat to your original question is that the stipulation that the research has to occur every six years is not a part of the generic definition of longitudinal studies.
What are the three types of longitudinal studies?
- There are a range of different types of longitudinal studies: cohort studies, panel studies, record linkage studies.
- These studies may be either prospective or retrospective in nature.
