Negotiating obligation and aspiration over time: A longitudinal qualitative study of regional quota medical students’ reflective accounts

INTRODUCTION: Regional quota programmes recruit medical students to address geographic physician maldistribution, but attached service obligations can complicate career and professional identity development. Little is known about how students negotiate a professional future that is partly structured in advance. Understanding this process may help educators support career development without equating commitment with compliance. We examined how regional quota medical students represent and renegotiate service obligations, professional aspirations, and possible professional selves over time. METHODS: We conducted a retrospective longitudinal qualitative study of 560 required reflective reports from 239 students at Tottori University, Japan, collected from 2022 to 2025. Using the Framework Method, we combined inductive thematic analysis with case-by-time matrices and in-depth longitudinal analysis of 25 students who submitted reports in each of the four years. Professional identity formation and self-determination theory informed interpretation after theme development. RESULTS: Three interrelated themes were identified: broadening community medicine beyond disease and location to persons, lives, communities, and systems; encounters making future professional selves imaginable; and conditional ownership, in which students reclaimed agency within service constraints without necessarily resolving ambivalence. Longitudinal cases showed deepening of existing commitments, reframing after encounters with credible role models, and persistent negotiation rather than a single developmental sequence. DISCUSSION: Educational programmes linked to service obligations may be most constructive when they make career options visible, provide credible role models, and allow students to question constraints while developing personally meaningful professional plans.
