Cross-level relationships between justice climate and organizational citizenship behavior: Perceived organizational support as mediator

We investigated the mediating role of perceived organizational support in the cross-level relationships between procedural, interpersonal, and informational justice climate and organizational citizenship behavior. Hospital staff in China (N = 468) participated in this study. Using hierarchical linear modeling, we found that procedural and interpersonal justice climate had a significantly positive effect on organizational citizenship behavior. Informational justice climate, however, did not have a significant effect on organizational citizenship behavior. In addition, perceived organizational support mediated the effect of procedural and interpersonal justice climate on organizational citizenship behavior. Theoretical and practical implications of our findings are discussed in relation to justice climate and organizational citizenship behavior.
