Mechanisms of Near-Peer Learning in a Longitudinal Clerkship: A Grounded Theory Study.

Longitudinal peer learning relationships enabled meaningful peer interaction that influenced medical students' clinical development and capability for clinical supervision.

Optimizing this peer learning environment and seeking new opportunities to use longitudinal peer learning in clinical environments could promote psychological safety and professional identity formation for medical students.
