Impostor syndrome among minority medical students who are underrepresented in medicine.

Objectives: Impostor syndrome (IS) is prevalent in medical professionals. However, little is known about the prevalence of IS among medical trainees and those who are underrepresented in medicine (UiM). Even less is known about the experiences of UiM students at predominantly white institutions (PWIs) and historically black colleges/universities (HBCUs) relative to their non-UiM peers. The purpose of this study is to investigate differences in impostor syndrome among UiM and non-UiM medical students at a PWI and a HBCU. We additionally explored gender differences in impostor syndrome among UiM and non-UiM students at both institutions.

Method: Medical students (N = 278) at a PWI (N = 183, 107 (59%) women) and a HBCU (N = 95, 60 (63%) women), completed an anonymous, online two-part survey. In part one, students provided demographic information, and in part two, students completed the Clance Impostor Phenomenon Scale, a 20-item self-report questionnaire that assessed feelings of inadequacy and self-doubt surrounding intelligence, success, achievements, and one's inability to accept praise/recognition. Based on the student's score, the level of IS was measured and placed into one of two levels: few/moderate IS feelings, or frequent/intense IS feelings. We conducted a series of chi-square tests, binary logistic regression, independent sample t-tests, and analysis of variance to test the main aim of the study.

Results: The response rate was 22% and 25% at the PWI and HBCU, respectively. Overall, 97% of students reported moderate to intense feelings of IS, and women were 1.7 times more likely than men to report frequent or intense feelings of IS (63.5% vs 50.5%, p = 0.03). Students at PWI were 2.7 times more likely to report frequent or intense IS than HBCU students (66.7% vs 42.1%, p< 0.01). In addition, UiM students at PWI were 3.0 times more likely to report frequent or intense IS compared to UiM students at HBCU (68.6 % vs 42.0%, p = 0.01). Computation of a three-way ANOVA with gender, minority status, and school type revealed a two-way interaction indicating that UiM women scored higher on impostor syndrome than UiM men at the PWI and HBCU. This trend was not observed among non-UiM students.

Conclusions: Impostor syndrome is informed by gender, UiM status, as well as environmental context. Efforts to provide supportive professional development for medical students should be directed towards understanding and combatting this phenomenon at this critical juncture of their medical career.
