The Psychological Mechanisms of Public Service Motivation: A Two-Wave Examination

To explore the psychological mechanism of public service motivation (PSM), we used a time-lagged design to examine the mediating effects of organizational identification on the relationship between PSM and work attitudes (i.e., job satisfaction) and behavior (i.e., community citizenship behavior). A two-wave study of 241 public servants from District A of a large metropolitan city in Eastern China was conducted. Controlling job security and demographic variables, results from a structural equation modeling showed the relationship between public service motivation and job satisfaction and the relationship between public service motivation and community citizenship behavior were partially mediated by organizational identification. Results also demonstrated that in comparison with job security, public service motivation contributed more to community citizenship behavior than job satisfaction. The study contributes to our understanding of public service motivation by illuminating a mechanism through which public service motivation influences work attitudes and behavior.
