Longitudinal developmental research design is defined as a developmental research design that examines development by making a series of observations or measurements over time. Typically, a group of individuals who are all the same age is measured at different points in time.
Longitudinal studies are studies in which a group of individuals is investigated over a relatively long period of time; analysis that focuses on studies of a particular group conducted repeatedly over a period of time. Longitudinal study involves the collection of data at different points in time, as contrasted with a cross-sectional study. Please see Cohort study, Panel study, and Trend study.
