= 292), we examine construct validity evidence for OCB-H with regard to its distinction from OCB-W and its unique nomological network. In Study 2, we further examine the distinction between OCB-H and OCB-W at the between- and within-person level using an experience sampling approach in a sample of 162 workers. Using results from multilevel confirmatory factor analysis, we show that between-person variance in OCB-H is considerably higher than for OCB-W, and that although OCB-H and OCB-W are strongly correlated at the between-person level, they are independent of one another at the within-person level. We also examine these two forms of OCB as parallel mediators of the relation between work engagement and work interfering with family. Results suggest OCB-H and OCB-W are indeed distinct in the strength of their relationships to work engagement and work interfering with family at between- and within-person levels.
