The Correlation Between International Medical Graduates' Self-Study Habits and Their United States Medical Licensing Examination (USMLE) Step 1 and Step 2 Clinical Knowledge (CK) Scores.

Abstract

To secure a residency in the United States, medical students must pass the United States Medical Licensing Examination (USMLE) Step 1 and Step 2 CK exams. This study examines the correlation between international medical graduates' (IMGs) self-study habits and their USMLE scores. A retrospective study was conducted with 51 anonymous third- and fourth-year IMGs from Saint James Medical School, IL, United States. Participants completed an online survey about their study habits and USMLE Step 1 and Step 2 CK scores. All participants were undergoing clinical clerkships at South Texas Health Hospitals in McAllen, TX. The highest mean Step 1 scores were 211.3 for completing ≥7,000 questions, 222.2 for 91-120 days of study, 209.2 for 76-100% time on practice questions, 229.7 for 16-19 hours/day of study, and 228.0 for 51-75% group study. The highest mean Step 2 CK scores were 241.0 for completing ≥6,000 questions, 239.8 for <30 days of study, 238.8 for 76-100% time on practice questions, 239.0 for 16-19 hours/day of study, and 237.5 for 26-50% group study. No significant relationship was found between study habits and passing Step 1 scores (p>0.05), but moderate correlations were found for completing ≥4,000 questions and 61-90 days of study. No significant relationship was found between study habits and the national average Step 2 CK score, but a strong correlation was found for 25-50% time on practice questions. While some study habits correlate with higher scores, no significant relationship was found between specific study habits and passing Step 1 or achieving the national average Step 2 CK score.
