Exploring Impostor Phenomenon During Onboarding Into a Military Medical School.

Our identified themes provide us with a better understanding of if and why military medical students experience IP during onboarding. Our findings are also consistent with the situated learning theory, which places emphasis on the sense of belonging and may provide a unique and insightful lens through which IP can be further explored and studied, particularly at a military medical school where various identities, dynamics, and aspirations can converge simultaneously. Additionally, our findings suggest that existing practices may benefit from a number of improvements including, but not limited to, tailoring onboarding activities to entail more reflective discussion using small groups, especially for topics related to diversity and inclusion, revisiting areas where students may feel inadequately prepared to transition and perform well in a medical school, reevaluating administrative and financial support that can be roadblocks to a student's transition into the new environment and removing these barriers, and ensuring cultural coherence (organizational alignment of vision and mission) among faculty, staff, and upperclassmen. Future research directions include better understanding how developing single or multiple, identities can impact a medical students' experience with IP during onboarding, pre-clerkship, clerkship, or post-clerkship period, if at all.
