概要	Longitudinal oral history is a qualitative research design in which the same participants are interviewed repeatedly over an extended period — months or years — using open-ended, narrative-focused conversations. By revisiting participants at multiple points in time, the researcher traces how individuals construct, revise, and reinterpret their personal stories as their lives unfold, capturing not just retrospective accounts but the dynamic, evolving nature of memory and meaning-making.	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.
