The validity of an experimental video examination.

This study investigated the validity of an experimental video examination that had previously been shown to be feasible and have reproducible scores for a sample of candidates taking the 1987 ABIM Cardiovascular Disease examination. Correlations of the three video formats of echocardiograms, ventriculograms, and arteriograms with traditional item formats, similar content multiple choice question scores, experience, and external measures suggest that the video formats could be a worthwhile addition to the examination.
