A longitudinal study follows and measures the same group of subjects over a period of time, allowing for observation of changes and development over time. This is different from a cross-sectional study, which takes a snapshot of different groups at one point in time, and a case study, which focuses on a single individual or group in depth. A cross-sequential study combines longitudinal and cross-sectional methods to examine both age and cohort effects.
