Abstract
This study examined how positive psychological capital (PsyCap) of international students is linked to their engagement and organizational citizenship behaviors (OCBs) in the Japanese higher education context. We also explored the mediation effect of engagement between PsyCap and OCBs, and the moderating effect of cultural adjustment on the mediation relationship. The results show that PsyCap is significantly related to OCBs, which is mediated by engagement. The moderation effect of cultural adjustment is also significant.
