A longitudinal study is a research design that involves repeated observations of the same variables over an extended period, often years or decades. This approach allows researchers to track changes and developments within the same subjects, making it particularly useful for studying trends, life events, and the long-term effects of certain variables. Longitudinal studies can be either observational or experimental and are often used in fields such as psychology, medicine, and Social Sciences.
