The relationship between objective structured clinical examinations (OSCEs) and standardized tests is not well known. We linked second-year medical students' physical diagnosis OSCE scores from 1998, 1999 and 2000 (n = 355) with demographic information, Medical College Admission Test (MCAT) scores, and United States Medical Licensing Examination (USMLE) Step 1 scores. The correlation coefficient for the total OSCE score with USMLE Step 1 score was 0.41 (p < 0.001). Two of 7 skills areas-diagnosis and identification of abnormality-were significant multivariate correlates of USMLE Step 1 score. OSCE station scores accounted for approximately 22% of the variability in USMLE Step 1 scores. A second-year OSCE in physical diagnosis is correlated with scores on the USMLE Step 1 exam, with skills that foreshadow the clinical clerkships most predictive of USMLE scores. This correlation suggests predictive validity of this OSCE and supports the use of OSCEs early in medical school.
客观结构化临床考试（OSCE）与标准化考试之间的关系尚不为人所知。我们将1998年、1999年和2000年二年级医学生的体格诊断OSCE成绩（n = 355）与人口统计学信息、医学院入学考试（MCAT）成绩以及美国医师执照考试（USMLE）第一步的成绩联系起来。OSCE总成绩与USMLE第一步成绩的相关系数为0.41（p < 0.001）。7个技能领域中的两个——诊断和异常识别——是USMLE第一步成绩的显著多变量相关因素。OSCE站点成绩约占USMLE第一步成绩变异性的22%。二年级体格诊断OSCE与USMLE第一步考试成绩相关，其中预示临床实习的技能对USMLE成绩的预测性最强。这种相关性表明了该OSCE的预测效度，并支持在医学院早期使用OSCE。
