Longitudinal studies follow participants over a long period of time, often years or even decades. This can result in high dropout rates as participants may move, lose interest, or die during the course of the study. This is less of a concern in cross-sectional, family, and twin studies, which typically involve only one point in time or a shorter period of follow-up.
