Σύνοψη	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.	Oral history is a qualitative research method that collects, preserves, and interprets first-person spoken accounts of past events, experiences, and social processes. By recording in-depth interviews with individuals who witnessed or participated in historical events, oral historians document perspectives that written records often exclude. The method bridges historical scholarship and social science, treating the narrator's memory, subjectivity, and voice as primary evidence rather than as limitations to be corrected.
