The Impact of Changing Step 1 to Pass/Fail Reporting on Anxiety, Learning Approaches, and Curiosity

Purpose Given the significance of the US Medical Licensing Exam (USMLE) Step 1 score moving from a 3-digit value to pass/fail, the authors investigated the impact of the change on students' anxiety, approach to learning, and curiosity. Method Two cohorts of pre-clerkship medical students at three medical schools completed a composite of four instruments: the State-Trait Anxiety Inventory, the revised two-factor Study Process Questionnaire, the Interest/Deprivation Type Epistemic Curiosity Scale, and the Short Grit Scale prior to taking the last 3-digit scored Step 1 in 2021 or taking the first pass/fail scored Step 1 in 2022. Responses of 3-digit and pass/fail exam takers were compared (Mann-Whitney U) and multiple regression path analysis was performed to determine the factors that significantly impacted learning strategies. Results There was no difference between 3-digit (n = 86) and pass/fail exam takers (n = 154) in anxiety (STA-I scores, 50 vs. 49, p = 0.85), shallow learning strategies (22 vs. 23, p = 0.84), or interest curiosity scores (median scores 15 vs. 15, p = 0.07). However, pass/fail exam takers had lower deprivation curiosity scores (median 12 vs. 11, p = 0.03) and showed a decline in deep learning strategies (30 vs. 27, p = 0.0012). Path analysis indicated the decline in deep learning strategies was due to the change in exam scoring (beta = - 2.0428, p < 0.05). Conclusions Counter to the stated hypothesis and intentions, the initial impact of the change to pass/fail grading for USMLE Step 1 failed to reduce learner anxiety, and reduced curiosity and deep learning strategies.
