ABSTRACT
A concern about personality inventories in diagnostic and decision-making contexts is that individuals will fake. Although there is extensive research on faking, little research has focused on how perceptions of personality items change when individuals are faking or responding honestly. This research demonstrates how the delta parameter from the generalized graded unfolding item response theory model can be used to examine how individuals' perceptions about personality items might change when responding honestly or when faking. The results indicate that perceptions changed from honest to faking conditions for several neuroticism items. The direction of the change varied, indicating that faking can operate to increase or decrease scores within a personality factor.
