Abstract
A previous study showed that the effects of the Big Five Personality Domains on Organizational
Citizenship Behavior (OCB), which is informal voluntary behavior by employees, are indirect and that
there is a need for clarification of the mediating mechanism between Big Five Personality Domains and
OCB. This study focused on “political skill” which is the ability to exercise organizational politics, and
examined the mediating effect of political skill in the effects of the Big Five Personality Domains on
OCB. Participants were 309 full-time workers in a Japanese enterprise (231 men and 78 women; mean
age 44.20 years, SD=8.16). Our results showed that “apparent sincerity” and “interpersonal influence”,
subscales of political skill are the intervening variable which explaining the partly process of the Big
Five Personality on OCB.
