A structural equation model of the effects of negative affectivity, leader-member exchange, and perceived job mobility on in-role and extra-role performance: A Chinese case

In this paper, we contrast the effects of leader-member exchange (LMX) with the effects of perceived job mobility on in-role performance and organizational citizenship behavior (OCB), We further model negative affectivity as the antecedent of both LMX and perceived job mobility and suggest that LMX and perceived job mobility mediated the relationship between negative affectivity and performance. We obtained matching data from supervisor and subordinates in a major battery manufacturing company in southern China, Subordinates provided the negative affectivity, perceived job mobility, and LMX assessment, and their immediate supervisors provided the in-role performance and OCB assessment. Results from a structural equation analysis show that both LMX and perceived job mobility predicted OCB, Instead of being a direct antecedent of OCB, the relationship between negative affectivity and OCB is found to be mediated by LMX and perceived job mobility. Theoretical implications of the results are discussed. (C) 1999 Academic Press.
