PSYCHOMETRIC PROPERTIES OF MULTISOURCE PERFORMANCE RATINGS - A METAANALYSIS OF SUBORDINATE, SUPERVISOR, PEER, AND SELF-RATINGS

The purpose of this investigation was to examine the psychometric prop erties (interrater reliabilities within source and correlations betwee n sources) of subordinate, supervisor, peer, and self-ratings of job p erformance. Different job types and dimension types were compared. Usi ng meta-analytic methodology, we found that subordinates showed the lo west mean reliability (.30) and supervisors showed the highest (.50), with peers in between (.37). Mean correlations between sources were lo w for subordinate ratings (.22 with supervisor,.22 with peer, and .14 with self-ratings) and for self-ratings (.22 with supervisor and .19 w ith peer ratings). The mean supervisor-peer correlation was higher at .34. Both reliabilities and correlations between sources tended to be higher for nonmanagerial and lower complexity jobs. Comparisons of bet ween-source correlations with within-source reliabilities indicated th at, with some qualifications, the different sources had somewhat diffe rent perspectives on performance. Dimension reliabilities differed som ewhat for interpersonal and cognitive dimensions.
