Data were collected from a sample of 262 Korean employees to (a) examine personality correlates of Organizational Citizenship Behaviors (OCBs) motivated by “good soldier” (i.e., prosocial values and organizational concern) and “good actor” (i.e., impression management [IM]) motives and (b) investigate how these OCB motives influenced actual coworker ratings of OCB. Personality variables were measured using the six-dimensional model of personality known as the HEXACO model. As hypothesized, (low) Honesty–Humility is the primary personality dimension underlying IM motivated OCB. Further, Conscientiousness positively related to OCB driven by each of the three motives. Agreeableness, Emotionality, and Openness to Experience also demonstrated relationships with the OCB motives. Second, OCBs for the organizational concern and IM motives, but not for the prosocial values motive, were positively associated with coworker ratings of OCB.
