Purpose: Peer evaluation is underused in medical education. The goals of this study were to validate in a multiinstitutional study a peer nomination form that identifies outstanding students in clinical competency and interpersonal skills, to test the hypothesis that with additional survey items humanism could be identified as a separate factor, and to find the simplest method of analysis.
Method: In 2003, a 12-item peer nomination form was administered to junior or senior medical students at three institutions. Factor analysis was used to identify major latent variables and the items related to those characteristics. On the basis of those results, in 2004 a simpler, six-item form was developed and administered. Student rankings based on factor analysis and nomination counts were compared.
Results: Factor analysis of peer nomination data from both surveys identified three factors: clinical competence, caring, and community service. New survey items designed to address humanism are all weighted with interpersonal skills items; thus, the second major factor is characterized as caring. Rankings based on peer nomination results analyzed by either factor analysis or simply counting nominations distinguish at least the top 15% of students for each characteristic.
Conclusions: Counting peer nominations using a simple, six-item form identifies medical student exemplars for three characteristics: clinical competence, caring, and community service. Factor analysis of peer nomination data did not identify humanism as a separate factor. Peer nomination rankings provide medical schools with a reliable tool to identify exemplars for recognition in medical student performance evaluations and selection for honors (e.g., Gold Humanism Honor Society).
