Tóm tắt	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.	Biographical research is a qualitative method that examines individual lives in depth — through life-history interviews, personal documents, letters, and autobiographical narratives — to understand how personal experience intersects with social, historical, and cultural forces. Rooted in Wilhelm Dilthey's hermeneutics and made prominent in sociology by Thomas and Znaniecki's study of Polish immigrants, it treats the individual life story as a window onto broader social structures and processes. It belongs to the narrative inquiry subfamily alongside oral history and life-story research.
