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.

Exercise stress testing, commonly known as a treadmill test, is a noninvasive procedure used to evaluate cardiovascular function and diagnose heart conditions.
Definition
An exercise stress test measures the heart's response to exertion using a treadmill or stationary bicycle. Chest electrodes record the heart's electrical activity through an ECG, and blood pressure is monitored regularly.
