概要	Longitudinal oral history method is a qualitative research design in which the same participants are interviewed repeatedly over an extended period — months or years — using oral history interviewing techniques. By returning to narrators across time, researchers can trace how personal accounts, identities, and interpretations of experience shift and evolve, capturing the processual and biographical dimensions of social life that a single interview cannot reveal.	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.
