The purpose of this study was to examine the relationship between performance on the Dental Admission Test (DAT) and Part I of the National Board Dental Examination (NBDE Part I) for students at the Harvard School of Dental Medicine (HSDM). This study was a retrospective cohort study, examining HSDM students over an eight-year period. Data regarding DAT and NBDE Part I scores were obtained from the Office of the Registrar. Descriptive statistics were computed for all study variables. Multiple linear regression analyses were subsequently computed to examine the relationship between DAT subtest scores and performance on NBDE Part I subtests. Goodness of fit for the models was evaluated using the R-squared value. Statistically significant associations were those with p-value =0.05. Data were available for 244 students who matriculated at HSDM during the period of 1995-2002. DAT reading comprehension scores were statistically significantly associated with performance on all four subsections of the NBDE Part I. DAT general and organic chemistry scores were associated with performance on the microbiology and pathology subtest of NBDE Part I. Performance on the perceptual ability test was associated with performance on the dental anatomy and occlusion subtest. Performance on the DAT reading comprehension subtest was the most reliable predictor of performance on the NBDE Part I. However, the variability in NBDE Part I scores is not accounted for significantly by variability in DAT scores.
本研究旨在探讨哈佛牙医学院（HSDM）学生的牙科入学考试（DAT）成绩与美国国家牙科医师资格考试第一部分（NBDE第一部分）成绩之间的关系。本研究为回顾性队列研究，对HSDM学生进行了为期八年的考察。关于DAT和NBDE第一部分成绩的数据来自注册办公室。对所有研究变量进行了描述性统计。随后进行了多元线性回归分析，以检验DAT子测试成绩与NBDE第一部分子测试成绩之间的关系。使用决定系数（R²值）评估模型的拟合优度。具有统计学意义的关联是p值 = 0.05的关联。有1995年至2002年期间进入HSDM的244名学生的数据。DAT阅读理解成绩与NBDE第一部分所有四个子部分的成绩在统计学上具有显著关联。DAT普通化学和有机化学成绩与NBDE第一部分微生物学和病理学子测试的成绩相关。感知能力测试成绩与牙科解剖学和咬合学子测试的成绩相关。DAT阅读理解子测试成绩是NBDE第一部分成绩最可靠的预测指标。然而，DAT成绩的变异性并不能显著解释NBDE第一部分成绩的变异性。
