Public service motivation and interpersonal citizenship behavior in public organizations: Testing a preliminary model

A good deal of research has demonstrated how public service motivation (PSM) facilitates desirable organizational attitudes and behaviors such as job satisfaction, organizational commitment, and work effort. Other research has demonstrated that PSM predicts higher levels of social capital and altruistic behavior in society. Between these two strands of PSM research, there is a gap in knowledge about whether PSM matters to citizenship behavior internal to the organization. This article tests the direct and indirect relationship between individual levels of PSM and interpersonal citizenship behavior using a structural equation model. We also account for the effect of organizational environment by incorporating a measure of co-worker support. We find that PSM has a direct and positive effect on interpersonal citizenship behavior in public organizations, even when accounting for the significant role of co-worker support.
