Faking under a nonlinear relationship between personality assessment scores and job performance.

This study investigated whether faking in personality assessments affects the prediction of job performance and consequences of selection decisions when a nonlinear relationship was assumed between personality scores and job performance. It was also examined whether a selection strategy suggested for nonlinear relationships reduces the adverse impact of faking on consequences of selection decisions. The findings from the item response theory-based simulations indicated that the prediction of job performance was affected by faking, whereas selection accuracy was not substantially affected by faking. The improvement in selection accuracy due to the strategy suggested for a nonlinear relationship was not noticeable. However, the suggested strategy reduced adverse impacts of faking on the estimation of selected applicants' performance scores. [ABSTRACT FROM AUTHOR]
