This study examined the relationship between job involvement and the five dimensions of organizational citizenship behaviors, using a sample of 1,110 from the People Republic of China. Results showed that job involvement related positively to all dimensions of OCBs. In addition, gender moderated the relationship between job involvement and three dimensions of OCBs, with males having a stronger, positive relationship between these constructs than females. The results further showed that party affiliation moderated the relationship between job involvement and three dimensions (...) of OCBs, with party members having a strong, positive relationship between these constructs than non-party members. The results are interpreted in light of the literature both on job involvement and OCBs, and limitations of this study are discussed. (shrink)
