Abstract
The relationship between public service motivation (PSM) and its outcomes (e.g., performance, job satisfaction, and organizational commitment) remains a central concern of scholars and practitioners in the public management field. Although a wide variety of studies have been conducted, the findings have not completely dispelled the suspicion about whether a direct and actual influence of PSM on outcomes exists. Meta-analysis is a systematic and quantitative process that synthesizes numerous results from original studies and can provide better parameter estimates through computing a mean effect size. Using a structural analysis of meta-analytic correlations, this study investigates the overall average effect sizes and the possibility of alternative effects (i.e., mediating effects) of other variables (i.e., job satisfaction and organizational commitment) on the PSM-performance relationship in order to specify these relationships. The structural analyses of meta-analytic correlations among PSM and outcomes show that PSM has mostly indirect effects on performance; that is, job satisfaction and organizational commitment have partial mediation effects on the relationship between PSM and individual performance.
