概要	Multiple case-based life history research is a qualitative design that collects full biographical accounts from several purposively selected individuals and then compares those life histories across cases to identify shared patterns, divergences, and contextual influences. By treating each person's life story as one analytic case, the approach blends the depth of life history methodology with the comparative rigor of multiple case study logic, producing findings that are both individually rich and cross-case meaningful.	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.
