RESUMO
BACKGROUND: Despite similar performance metrics, women medical trainees routinely self-assess their own skills lower than men. The phenomenon of a "confidence gap" between genders, where women report lower self-confidence independent of actual ability or competency, may have an important interaction with gender differences in assessment. Identifying whether there are gender-based differences in how confidence is mentioned in written evaluations is a necessary step to understand the interaction between evaluation and the gender-based confidence gap. OBJECTIVE: To analyze faculty evaluations of internal medicine (IM) residents for gender-based patterns in the use of iterations of "confidence." DESIGN: We performed a retrospective cohort study of all inpatient faculty evaluations of University of Pennsylvania IM residents from 2018 to 2021. We performed n-gram text-mining to identify evaluations containing the terms "confident," "confidence," or "confidently." We performed univariable and multivariable logistic regression to determine the association between resident gender and references to confidence (including comments reflecting too little confidence), adjusting for faculty gender, post-graduate year (PGY), numeric rating, and service. SUBJECTS: University of Pennsylvania IM residents from 2018 to 2021. KEY RESULTS: There were 5416 evaluations of IM residents (165 women [51%], 156 men [49%]) submitted by 356 faculty members (149 women [51%]), of which 7.1 % (n=356) contained references to confidence. There was a significant positive association between the mention of confidence and women resident gender (OR 1.54, CI 1.23-1.92; p<0.001), which persisted after adjustment for faculty gender, numeric rating, and PGY level. Eighty evaluations of the cohort explicitly mentioned the resident having "too little confidence," which was also associated with women resident gender (OR 1.66, CI 1.05-2.62; p=0.031). CONCLUSION: Narrative evaluations of women residents were more likely to contain references to confidence, after adjustment for numerical score, PGY level, and faculty gender, which may perpetuate the gender-based confidence gap, introduce bias, and ultimately impact professional identity development.
