Introduction In the spirit of enacting an educational model of guided, collective reflection to support positive professional identity construction in healthcare learners, we implemented a reflection-based course for medical students transitioning to clerkship with three goals: to sensitize learners to the hidden curriculum; to provide a safe and confidential forum to discuss their experiences; and to co-construct strategies to deal with the pressures in the clinical environment

Methods We used a design-based research protocol. Twelve students participated in ten sessions starting during their transition to clerkship. Faculty debriefed after each session, adjusting the format of the subsequent sessions. Data included student logs, transcripts of the course sessions, faculty debriefings, and the course evaluation. Data were analyzed via an iterative process of independent coding and discussion.

Results The main adjustments to the course were to eliminate didactic content in favour of using prompts prior to course sessions and de-emphasizing written reflection. Participants felt the course achieved its three goals and students reported enhanced resiliency during transition to clerkship, although, despite prompting, students offered no examples of their joining in with the negative behaviours around them.

Conclusions The course was successful in its key objectives. However, a key aspect of reflection, students noticing their own behaviour in the moment as something that needs to be reflected on, was challenging.
