摘要：This article investigates the effects of job involvement, affective organizational
commitment, and collectivism on organizational citizenship behavior (OCB) using data
collected from 131 professors and clerical workers in a private Japanese university. Results
show that job involvement had a significantly positive relationship on civic virtue and helping
behavior, and affective organizational commitment had a significantly positive effect on
helping behavior and sportsmanship. Collectivism also positively influenced civic virtue and
helping behavior. In addition, the effect of affective organizational commitment on civic
virtue was moderated by collectivism so that affective organizational commitment had a
stronger effect when collectivism was weak than when collectivism was strong.
