Further Validation of Methods for Evaluating the Performance of Physicians

&Harris, 1957). The experimental Efficiency Report contains four kinds of performance evaluation methods: 50 Forced-Choice tetrads (FC), a 10-point scale for rating Job Proficiency (JP), eight 10-point scales for rating various Personal Qualifications (PQ), and a 22-item Check List (CL). When the original and cross-validation samples of physicians were combined in the previous study, validity coefficients for the various evaluation methods ranged from .54 to .62 and produced a multiple correlation of .68 against a rating criterion, the average rating given by work associates in evaluating a physician’s Work Performance. Optimum weights for combining the evaluation methods in the Report were determined by the Wherry-Doolittle method (Garrett, 1947). The FC and JP sections were selected as predictors with about equal weights, and the resulting multiple was significantly larger than the highest single validity. The present study, undertaken as a part of the Officer Selection and Evaluation Program (Newman, 1951), is a further validation of
