Changes in self-confidence in professional, personal, and scientific skills by gender during physician-scientist training at the University of Pittsburgh.

Introduction: Persistence in physician-scientist careers has been suboptimal, particularly among women. There is a gender gap in self-confidence in medicine. We measured the impact of our physician-scientist training programs on trainee's confidence in professional, personal, and scientific competencies, using a survey measuring self-rated confidence in 36 competencies across two timepoints.

Methods: Results were analyzed for the full survey and for thematic subscales identified through exploratory factor analysis (EFA). A mixed effects linear model and a difference in differences (DID) design were used to assess the differential impact of the programing by gender and career level.

Results: Analysis included 100 MD-PhD or MD-only medical student or resident/fellow trainees enrolled between 2020 and 2023. Five subscales were identified through EFA; career sustainability, science productivity, grant management, goal setting, and goal alignment (Cronbach's alpha 0.85-0.94). Overall, mean scores increased significantly for all five subscales. Women significantly increased their confidence levels in all five areas, whereas men increased only in science productivity and grant management. Mixed effects models showed significant increases over time for women compared to men in career sustainability and goal alignment. Residents and fellows had greater increases than medical students across all subscales.

Conclusion: Physician-scientist trainees fellows increased their confidence in personal, professional, and scientific skills during training. Training had a greater impact on women than men in building confidence in sustaining careers and aligning their goals with professional and institutional priorities. The magnitude of increased confidence among residents and fellows exceeded that in medical students.
