The purpose of this study was to examine the equivalence of self-reports and managerial ratings of salesperson job performance. A meta-analysis showed that the two measures exhibited low convergent validity (mean corrected correlation = 0.19), which indicated that they are not interchangeable. The predictive validity of self-reports and managerial ratings was compared. Managerial ratings had a corrected mean correlation of 0.44 with objective performance, whereas the corrected mean correlation between self-reports and objective measures was 0.34. Further meta-analytic investigations showed that the divergence between self-reports and managerial ratings was attributable to the performance effect. A discussion of the findings and avenues for further research are also provided.
