Perceived Supervisor Support and Organizational Citizenship Behavior: The Role of Organizational Commitment

Abstract

This article examines the relationship between perceived supervisor support (PSS) and organizational citizenship behavior (OCB), and the mediating role of organizational commitment in this relationship. The moderating effect of organizational tenure on the relationship between PSS and organizational commitment was also tested. Based on 238 responses from Chinese employees, the author performed hierarchical regression analyses to examine the mediation (also bootstrapping analyses) and moderation models. Results showed that employees perceiving more support from the supervisor were more likely to conduct OCB, and this greater likelihood, to a large extent, was realized through employees’ commitment to the organization. The relationship between PSS and organizational commitment was stronger among employees with longer tenure.
