Abstract: | Previous literature suggests that performance ratings are saturated with rater-related idiosyncratic variance. Given that modern psychometric theories relegate this source of variance to measurement error, it has not been the subject of much previous research. Of importance, identifying and estimating the variance components underlying idiosyncratic rater variance will inform our understanding of the nature of this variance. In a sample of managerial performance ratings we report on components of variance and find that the idiosyncratic rater variance component is about one third rater main effects variance, one third Rater × Ratee interaction effects variance, and one third upper-bound Rater × Ratee × Dimension interaction effects variance. Further, results indicate that variance components are moderated by the acquaintanceship time between the rater and the ratee. |
