*Corresponding author. Abstract This study aims to investigate the mediating effect of affective commitment on the relationship between personality and organizational citizenship behavior (OCB) in a non-Western culture. We attempt to increase understanding of how personality and work attitudes affect OCB in a culture where relationships are highly valued. Data col-lected among employees in an Indonesian cement factory indicate that affective commit-ment partially mediates the relationship between extraversion and OCB directed at individuals (OCB-I) and at the organization (OCB-O), and also partially mediates the relationship between emotional stability and OCB-O. We confirm the importance of examining work attitudes in personality-OCB relationships in collective cultures.
