Medical schools use a variety of preadmission indices to select potential students. These indices generally include undergraduate grade point average (GPA), Medical College Admission Test (MCAT) scores, and preadmission interviews.
To investigate whether the admission indices used by Midwestern University Arizona College of Osteopathic Medicine are associated with the academic and clinical performance of their students.
Associations between the prematriculation variables of undergraduate science GPA, undergraduate total GPA, MCAT component scores, and interview scores and the academic and clinical variables of the first- and second-year medical school GPA, Comprehensive Osteopathic Medical Licensing Examination-USA (COMLEX-USA) Level 1 and Level 2-Cognitive Evaluation (CE) total and discipline scores, scores in clinical rotations for osteopathic competencies, COMLEX-USA Level 2-Performance Evaluation passage, and match status were evaluated. Two-tailed Pearson product-moment correlations with a Bonferroni adjustment were used to examine these relationships.
The traditional predictors of science and total undergraduate GPA as well as total and component MCAT scores had small to moderate associations with first- and second-year GPA, as well as COMLEX-USA Level 1 and Level 2-CE total scores. Of all predictors, only the MCAT biological sciences score had a statistically significant correlation with failure of the COMLEX-USA Level 2-Performance Evaluation examination (P=.009). Average interview scores were associated only with the osteopathic competency of medical knowledge (r=0.233; n=209; P=.001), as assessed by clerkship preceptors. No predictors were associated with scores in objective structured clinical encounters or with failing to match to a residency position.
The data indicate that traditional predictors of academic performance (undergraduate GPA, undergraduate science GPA, and MCAT scores) have small to moderate association with medical school grades and performance on COMLEX-USA Level 1 and Level 2-CE. This finding requires additional research into the value of the interview in the medical school admissions process and the availability of alternatives that allow better prediction and assessment of applicant performance.
医学院校使用多种入学前指标来选拔潜在学生。这些指标通常包括本科平均绩点（GPA）、医学院入学考试（MCAT）成绩和入学前面试。
调查中西部大学亚利桑那整骨医学院使用的入学指标是否与其学生的学业成绩和临床成绩相关。
评估本科理科GPA、本科总GPA、MCAT各部分成绩和面试成绩等入学前变量与医学院校一年级和二年级GPA、美国整骨医学综合执照考试（COMLEX-USA）1级和2级认知评估（CE）总分及各学科成绩、整骨医学能力临床轮转成绩、COMLEX-USA 2级表现评估通过率和匹配情况等学业和临床变量之间的关联。使用经Bonferroni校正的双尾Pearson积差相关来检验这些关系。
本科理科和总GPA以及MCAT总分和各部分成绩这些传统预测指标与一年级和二年级GPA以及COMLEX-USA 1级和2级CE总分之间存在小到中等程度的关联。在所有预测指标中，只有MCAT生物科学成绩与COMLEX-USA 2级表现评估考试未通过存在统计学显著相关性（P = 0.009）。平均面试成绩仅与由临床带教教师评估的医学知识整骨医学能力相关（r = 0.233；n = 209；P = 0.001）。没有预测指标与客观结构化临床考试成绩或未匹配到住院医师职位相关。
数据表明，学业成绩的传统预测指标（本科GPA、本科理科GPA和MCAT成绩）与医学院校成绩以及COMLEX-USA 1级和2级CE表现之间存在小到中等程度的关联。这一发现需要对面试在医学院校招生过程中的价值以及能够更好地预测和评估申请人表现的替代方法的可用性进行更多研究。
