Question

Quizplus · Accepted Answer

Longitudinal studies follow participants over a long period of time, which increases the risk of losing participants due to drop-out rates or even death. Cross-sectional studies, family studies, and twin studies are not necessarily longitudinal and therefore do not face as high of a risk for losing participants over time.
