Longitudinal studies require a significant amount of time and effort from participants, and as a result, it is possible that some participants may drop out of the study over time. This can lead to a reduction in the sample size and a potential bias in the results. A, B, and D are not drawbacks of longitudinal studies. Cohort effects refer to the influence of a person's birth cohort on their development, and it is not a drawback specific to longitudinal studies. While causality can be difficult to establish in any study, longitudinal studies are particularly useful for examining causality because they follow participants over time. Finally, longitudinal studies can have high generalizability because they track individuals over time rather than relying on cross-sectional comparisons.
