Longitudinal designs track individuals or groups over a period of time, which allows researchers to examine changes within the same individuals or groups. This design helps to control for cohort effects, which can impact cross-sectional designs where data is collected at one point in time from different age cohorts. Additionally, longitudinal designs may be more impacted by attrition but can adjust for this through various statistical methods. Therefore, the advantage of a longitudinal design is its ability to avoid issues associated with cohort effects. It does, however, require more time to perform.
