概要	Longitudinal life history research follows the same participants across multiple points in time, collecting repeated in-depth accounts of how their life stories evolve, how they narrate past events differently over time, and how biography intersects with social change. It combines the interpretive depth of life history methodology with the temporal sensitivity of longitudinal design, capturing both the content of lived experience and its unfolding across the life course.	Life history research is a qualitative method that captures the full arc of an individual's life — or a significant portion of it — through extended biographical interviewing and analysis of personal documents. Rooted in early Chicago School sociology, the method treats each life story as a window into broader social, cultural, and historical forces. The researcher and participant co-construct a narrative account that illuminates how personal experience is shaped by, and in turn shapes, wider social structures and processes.
