BACKGROUND
The degree to which scores on the mini-Clinical Evaluation Exercise (mCEX), a feedback tool, correlate with performance on future clinical skills examinations is unknown.
METHOD
Medicine clerkship students in 2006 and 2007 completed eight mCEX cards and took an end-of-clerkship standardized patient (SP) exam and an end-of-year multidisciplinary SP exam. Pearson correlations estimated relationships between average mCEX scores and scores on the SP exams.
RESULTS
A total of 244 students met inclusion requirements. Observed correlations between mCEX performance and SP checklist/notes and interpersonal skills scores ranged from 0.15 to 0.39. Disattenuated estimates were 0.21 to 0.50.
CONCLUSIONS
This is one of the first studies comparing mCEX and SP exam performance. Explanations for the generally modest correlations merit further consideration.
背景
迷你临床演练评估（mini-Clinical Evaluation Exercise，mCEX）是一种反馈工具，其分数与未来临床技能考试成绩的相关性尚不清楚。
方法
2006 年和 2007 年的医学实习学生完成了 8 张 mCEX 卡片，并参加了实习结束时的标准化患者（SP）考试和年末的多学科 SP 考试。Pearson 相关系数估计了 mCEX 平均分数与 SP 考试分数之间的关系。
结果
共有 244 名学生符合纳入标准。mCEX 表现与 SP 检查表/记录和人际交往技能分数之间的观察相关性在 0.15 到 0.39 之间。去关联估计值在 0.21 到 0.50 之间。
结论
这是比较 mCEX 和 SP 考试成绩的首批研究之一。对这些相关性普遍较小的解释值得进一步考虑。
