Empirical studies have found a positive relationship between public service motivation (PSM) and individual performance. However, it is unclear what public service motivated employees are doing in terms of behavior that makes them perform. Moreover, it is uncertain whether PSM inspires similar behaviors among employees in different contexts. Conceptualizing performance as a multidimensional construct, this study investigates the relationship between PSM and self-reported output, service outcome, responsiveness, and democratic outcome behaviors. Using structural equation modeling on survey data from 459 employees in people-changing (service production, aimed at changing the user) and 461 employees in people-processing (service regulation, categorizing, and processing users) organizations, the results show that PSM is related to all performance-related behaviors in the people-changing group, but neither to output nor responsiveness in the people-processing group. PSM’s relationship to behavior may thus differ between contexts.
