longitudinal case studies

Longitudinal case studies are a research method where a single person, group, or organization is studied in depth over an extended period of time. This approach allows researchers to observe changes, developments, or patterns that occur over months or years. By repeatedly collecting data at different points, they can understand how and why certain factors influence outcomes. This method provides detailed, real-world insights into processes and behaviors, making it valuable in fields like psychology, medicine, and social sciences for tracking progress and understanding long-term effects.
