Abstract
The selection and subsequent performance of 212 internal medicine residents was examined byfactor analysis andpath analysis. A three-factor solution accountedfor most of the variance among the nine selection variables. These three factors, labeled Board Scores, Faculty Evaluations, and Academic Distinction, were then combined with in-training residencyperformance evaluations and composite scores on the ABIM certifying examination to produce a comprehensive path model of house staff selection and performance. The Academic Distinction factor emerged as the strongest predictor of residency performance,; the Faculty Evaluationsfactor was also a significant component of the model. Standardized test scores correlatedpoorly with clinicalperformance. The data suggest that increased attention to the content of letters of reference could substantially improve their predictive validity. Other means of reporting subjective evaluations may also be needed to increase the stature of noncognitive attributes in house staff selection decisions.
