The Effect of Similarity on Performance Ratings and Interrater Agreement
研究监狱警卫的同事和主管对其绩效评分，发现主管与下属的教育相似性显著影响评分，而主管与下属对工作维度重要性的共识以及下属与同事的年龄相似性也有一定影响。
Although training and use of multiple raters have been suggested to minimize demographic and individual biases on performance evaluations (Latham & Wexley, 1981), use of multiple raters often results in low interrater reliability which compounds the difficulty of establishing performance rating validity. The present study investigated the performance ratings made by the peers and supervisors of correction's officers, i.e., prison guards. Attention wasfocused on two issues: (1) the effects of rater and ratee personal, attitudinal, and relationship variables on performance ratings, and (2) examining performance "perspective differences" as an explanation of rating agreement. Results indicated that supervisor-subordinate educational similarity was significantly related to subordinate's performance rating. Supervisor-subordinate agreement on job dimension importance and subordinate age similarity with peer raters were also marginally related to performance ratings. The findings are discussed from the perspectives of shared cognitive schemas ofjob behaviors and practical implications.
