Abstract
Understanding what drives public service motivation and its impacts is crucial for improving public sector performance. This meta-analysis synthesized the antecedents and outcomes of public service motivation based on the job demands-resources (JD-R) model. Incorporating 177 studies and 179 independent samples, with a total of 319 effect sizes, the results indicated the following: (1) Job resources and personal resources were positively related to public service motivation, while hindrance demands were negatively related to it. (2) Public service motivation had a positive relationship with overall job attitudes, job satisfaction, organizational commitment, and work engagement. It also had a positive relationship with overall job performance, in-role performance, and extra-role performance. (3) In terms of the antecedents, individualism/collectivism moderated the relationship between job resources and public service motivation, as well as the relationship between hindrance demands and public service motivation. As for the outcomes, individualism/collectivism moderated the relationship between public service motivation and both job attitudes and job performance. This study contributes to a comprehensive understanding of the antecedents and outcomes of public service motivation, offering valuable insights for future research and serving as a reference for theory development and practical application.
