A longitudinal study is a research method in which the same individuals or subjects are observed and studied repeatedly over an extended period of time. This approach enables researchers to examine patterns of growth, development, and behavioral changes while minimizing the influence of individual differences.
Longitudinal studies are widely used in developmental psychology, education, and social sciences to understand how people change across different stages of life. Although they provide valuable insights into long-term development, they often require considerable time, effort, and resources to complete.
In contrast, a cross-sectional study compares different groups of people at a single point in time, while a life history study focuses on an individual\'s personal experiences rather than systematically tracking the same participants over time.
