Measuring Uncertainty Intolerance in Surgical Residents Using Standardized Assessments

Physicians are frequently called on to make medical decisions despite being uncertain about the outcomes of these choices. The psychological stress associated with these dilemmas, known as "Uncertainty Intolerance" (UI), can significantly impact the quality of a physician's practice as well as their own mental health. Coping with uncertainty is an important competency that all residents must master, and some residency programs are introducing new education initiatives aimed at improving UI. However, currently there is no standard protocol for measuring UI or the effectiveness of such interventions and there are no established methods for identifying the residents who would most benefit from the training. In this study, we aim to use the Physician Reaction to Uncertainty (PRU) and Physician Risk Attitude (PRA) scales as assessments for UI in surgical residents, and to determine if Myers-Briggs Type Indicator (MBTI) personality factors are associated with PRU and PRA scores and can be used to identify residents who are more likely to have higher UI.

The PRU and PRA scales, and the MBTI assessment were administered to a total pool of 71 general surgery residents. In addition to the survey questions, residents provided information regarding their gender (male or female), and stage of training (junior or senior).

In total, 45 male residents and 25 female residents completed the PRA and PRU scales (98.6%). There were no statistically significant differences when comparisons were made between junior and senior residents or male and female residents. Thirty seven male residents and 18 female residents also completed the MBTI assessment (80.4% and 72%, respectively). PRU and PRA scores were analyzed with respect to personality factors to determine if certain dichotomies are associated with increased UI. There was a trend toward higher UI in individuals identifying with Judging.

In this study, we have conducted a pilot study using the PRU and PRA scales to measuring the success of our new education initiatives aimed at improving uncertainty tolerance. We found that the PRU and PRA assessments were simple to administer and had a high completion rate. Our findings also suggest that individuals who identify with Judging may better tolerate the uncertainties associated with surgical practice, although larger studies will be required to determine if MBTI factors are linked to UI in surgical residents.
