To investigate the extent to which Medical College Admission Test (MCAT) subscores predict the overall academic performance of osteopathic medical students.
We examined the value of MCAT subscores in predicting students' global academic performance in osteopathic medical school, as defined by grade point average in basic science (basic GPA), clinical instruction (clinical GPA), cumulative grade point average (total GPA), and national licensing examination scores on the Comprehensive Osteopathic Medical Licensing Examination-USA (COMLEX-USA) Level 1 and Level 2. Subjects were 434 osteopathic medical students of the Oklahoma State University College of Osteopathic Medicine in Tulsa who either graduated or were expected to graduate between the years 1999 and 2003. Standard, multivariate linear regression analyses were conducted for each of the five performance variables to assess the relative importance of MCAT subtest scores and cumulative undergraduate GPA (total UGPA) in predicting academic performance.
Total UGPA was the most important, significant predictor (beta=.13-.33) in overall student academic performance for all five analyzed variables. Less predictive of overall academic performance (beta=-.01-.21) were MCAT subcores. However, the MCAT biological sciences subscore was a significant predictor of basic GPA (beta=.14), the MCAT physical sciences subscore significantly predicted COMLEX-USA Level 1 scores (beta=.15), and the MCAT verbal reasoning subscore significantly predicted COMLEX-USA Level 2 scores (beta=.21). The subscore for the MCAT writing sample was not a significant predictor of overall academic performance.
Total undergraduate GPA had the highest predictive value for academic performance as measured by basic GPA, clinical GPA, total GPA, and COMLEX-USA Level 1 and Level 2 scores. The present study found MCAT subscores to be of limited predictive value in determining global academic performance.
探讨医学院入学考试（MCAT）各科目分数对骨科医学专业学生整体学业成绩的预测程度。
我们研究了MCAT各科目分数在预测骨科医学院学生整体学业成绩方面的价值，整体学业成绩由基础科学课程平均绩点（基础GPA）、临床教学课程平均绩点（临床GPA）、累积平均绩点（总GPA）以及美国综合骨科医学执照考试（COMLEX - USA）1级和2级的国家执照考试成绩来定义。研究对象为俄克拉荷马州立大学塔尔萨分校骨科医学院的434名学生，他们于1999年至2003年间毕业或预计毕业。对五个成绩变量分别进行标准多元线性回归分析，以评估MCAT各科目考试分数和本科累积平均绩点（总本科GPA）在预测学业成绩方面的相对重要性。
在所有五个分析变量中，总本科GPA是学生整体学业成绩最重要、最显著的预测指标（β = 0.13 - 0.33）。MCAT各科目分数对整体学业成绩的预测性较低（β = -0.01 - 0.21）。然而，MCAT生物科学科目分数是基础GPA的显著预测指标（β = 0.14），MCAT物理科学科目分数显著预测COMLEX - USA 1级考试成绩（β = 0.15），MCAT语言推理科目分数显著预测COMLEX - USA 2级考试成绩（β = 0.21）。MCAT写作样本的科目分数不是整体学业成绩的显著预测指标。
本科累积平均绩点对基础GPA、临床GPA、总GPA以及COMLEX - USA 1级和2级考试成绩所衡量的学业成绩具有最高的预测价值。本研究发现，MCAT各科目分数在确定整体学业成绩方面的预测价值有限。
