BACKGROUND:The purpose of this study was to investigate the fit of a hypothesized model of medical students' diagnostic or clinical reasoning skills based on their aptitude for medical school, basic science achievement, and clinical competency measures.
METHOD:A total of 589 medical students who received their MD from 1994 to 2002 participated in this study. Confirmatory factor analysis was used to evaluate the fit of theoretical models of clinical reasoning using measures of basic science and clinical knowledge.
RESULTS:The results provided support for a three-factor model of medical student performance (Bentler's Comparative Fit Index = .905, standardized root mean squared residual = .054, root mean squared error of approximation = .105). The clinical reasoning skills of medical students were influenced by an independent relationship between latent variables of basic science achievement and clinical competency.
CONCLUSION:The findings support a theoretical model of diagnostic or clinical reasoning that treats the basic science and clinical knowledge of medical students as distinct domains.

背景：本研究的目的是根据医学生对医学学校的才能，基础科学成就和临床能力测评的假设，研究假设模型对医学生诊断或临床推理能力的适合性。
方法：1994年至2002年，共有589名医学博士获得了医学博士学位。验证性因素分析用于使用基础科学和临床知识的方法来评估临床推理理论模型的拟合度。
结果：该结果为医学学生表现的三因素模型提供了支持（Bentler比较拟合指数= .905，标准化均方根残差= .054，均方根近似误差= .105）。基础医学成就的潜在变量与临床能力之间的独立关系影响着医学生的临床推理能力。
结论：这些发现支持诊断或临床推理的理论模型，该模型将医学生的基础科学和临床知识视为不同的领域。
