Medical Students' Reflections on Transitioning to Their First General Practice Placement: Qualitative Descriptive Study.

Background: Transitioning from preclinical to clinical training is a critical milestone of "becoming and being" in a medical student's journey. Despite simulation-based learning, real-world clinical exposure remains indispensable in shaping professional identity. The clinical learning environment is a complex interplay of social, cultural, and organizational factors that influence students' development as future health care professionals. Objective: This study explores medical students' reflections on their first clinical placement in general practice, aiming to understand their experiences, challenges, and the clinical learning environment's role in their learning and developing professional identity formation as a step toward establishing a conceptual framework and a common language for educators, which we hope will promote further advances to support beneficial professional identity formation. Methods: We analyzed reflections from fourth-year medical students following their initial general practice placement. A qualitative descriptive approach grounded in naturalism was employed to explain our participants' transitioning encounters in clear, everyday language to ensure their experiences were presented in their own words, without bias. Content thematic analysis was conducted to identify key themes related to their experiences. Results: Students' reflections revealed a startled cohort unprepared for the epistemological, emotional, and practical realities of clinical work. Many assumed that classroom "knowing" would seamlessly translate into clinical "doing" but were met instead with uncertainty, failure, and emotional overwhelm, often manifesting as shame, guilt, and withdrawal. These experiences illuminated a fracture between knowledge and knowing, underscored by students' prereflective epistemological beliefs and varying degrees of supervisory preparedness. While emotional and cognitive struggles were widespread, rare instances of supportive mentorship and feedback significantly bolstered students' confidence and participation. Conclusions: Reflection offered a valuable window into how students think, feel, and act during this critical transition, but it is not a cure-all. Reflection should be positioned as a developmental and communal tool within a broader scaffolding that includes early skills preparation, role clarity, psychological safety, and trained supervisors. Structured shared reflective circles and narrative listening sessions can help normalize uncertainty, support identity formation, and foster resilience during students' entry into clinical practice and can ease the journey of "becoming and being."
