Grit in Medical Education: Differing Perspectives of Residents and Mentors

Background Increasing concerns about depression and burnout in residents have led to a recent focus on assessing "non-cognitive" traits in residents and residency applicants. One attribute that has received significant attention is grit, defined as trait-level perseverance and passion for long-term goals^. With an objective measure available, an important question is under what circumstances of administration is that measure reliable and accurate. The goal of this study was to ascertain whether internal medicine residents and their faculty mentors were congruent in their ratings of resident grit, or if not, how the ratings differed.  Methods Subjects were internal medicine residents (N=42) at a community-based university-affiliated hospital internal medicine residency program. Near the end of the academic year 2019, residents completed the GRIT-S (short form). As each resident is assigned a mentor during their training, each resident's mentor was also asked to complete the GRIT-S based on their view of their mentee.  Results This study failed to find a significant correlation between resident self-ratings of grit and those of their mentors. Conclusions The results of these two studies underscore the difficulty in obtaining accurate assessments of non-cognitive traits. These results further the understanding of the role of grit and raise important questions about how assessments might be used to assure validity. Further areas of inquiry into this potentially important characteristic are suggested.
