Effects of impression management and self-deception on the predictive validity of personality constructs.
This study tests whether 2 types of response distortion (self-deception and impression management) affect the predictive validity of 2 of the "Big 5" personality dimensions, conscientiousness and emotional stability, in 2 applicant samples of long-haul semitruck drivers (n = 147 and n = 139). As hypothesized, conscientiousness (p = -.26 and -.26) and emotional stability (p = -.23 and -.21) were valid predictors of voluntary turnover in the 2 samples. Also as hypothesized, conscientiousness was a valid predictor of supervisory ratings of performance (p = .41 and .39) in the 2 samples. Although not hypothesized, emotional stability was also significantly related to supervisor ratings of performance (p = .23 and .27). Results from structural equations modeling indicated that applicants did distort their scores on both personality dimensions and the distortion occurred both through self-deception and impression management; however, neither type of distortion attenuated the predictive validities of either personality construct.
