Breaking the Cycle: A Qualitative Study of Factors That Mitigate Impostor Phenomenon Among Internal Medicine Residents.

<b>Background</b> Impostor phenomenon (IP) describes feelings of inadequacy often experienced by individuals struggling to internalize success despite evidence to the contrary. IP is common in medicine and can be experienced as a cycle following exposure to an achievement-focused task, leading to fear of being found out as an impostor. Prior research describes IP characteristics, yet few studies have identified factors that mitigate IP among medical residents. <b>Objective</b> To understand factors that moderate IP among internal medicine (IM) residents. <b>Methods</b> We conducted a qualitative study using one-on-one semistructured interviews with 28 IM residents at a single academic health center from May to June 2020. To ascertain the prevalence of IP, informants completed a 20-item Clance Impostor Phenomenon Scale (CIPS) questionnaire. Using a constructivist thematic approach investigators independently coded transcripts to identify factors mitigating IP. <b>Results</b> Twenty-eight of 53 (53%) eligible residents participated in the study. Most informants were female (21 of 28, 75%) and in their second postgraduate year of training (12 of 28, 43%). The mean CIPS score was 63. When faced with an achievement-focused task, informants describe feelings of inadequacy, avoidance behaviors, distortion of feedback, and attribution beliefs. Internal factors found to moderate IP include (1) reframing attribution beliefs; (2) accepting feedback; and (3) acknowledging strengths. External factors include (1) mentors, coaches, and role models; (2) formal opportunities to share IP experiences; and (3) growth-oriented learning environments. <b>Conclusions</b> This qualitative study describes internal and external factors that potentially mitigate impostor feelings, thereby interrupting the cyclical nature of IP among IM residents.
