ON THE INTERCHANGEABILITY OF OBJECTIVE AND SUBJECTIVE MEASURES OF EMPLOYEE PERFORMANCE - A METAANALYSIS

A meta-analysis of studies containing both objective and subjective ratings of employee performance resulted in a corrected mean correlation of 389. This value, although significantly greater than zero, indicates that objective and subjective performance measures should not be used interchangeably Moreover, in no moderator subgroup examined did the correlation suggest convergent validity. After discussing issues related to resolving the previous anomalies of primary and meta-analytic results, a secondary analysis suggested that objective and subjective measures of the same construct at the same level may be used interchangeably. The secondary analysis, however, was based on a very limited sample. Future research should address the appropriate dimensionality of employee performance.
