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.	Longitudinal narrative research is a qualitative design that follows participants across multiple time points, gathering and analyzing their stories to understand how experiences, identities, and meanings evolve over time. Rooted in Clandinin and Connelly's narrative inquiry tradition, it treats human experience as fundamentally storied and temporal — what matters is not just what happened but how people narrate, revise, and make sense of their lives as circumstances change.
