A meta-analysis of the effects of job satisfaction on organizational outcomes: Evidence from the Korean National Police

This is the authors' abstract. We don't add key points for this paper.

This study conducted a meta-analysis to examine the associations between job satisfaction and key organizational outcome variables—organizational commitment, turnover intention, organizational citizenship behavior, and police performance—within the context of the Korean National Police. Following PRISMA procedures, a systematic search of the literature was performed, yielding 78 relevant studies and a total of 87 effect sizes for analysis. The results indicate that job satisfaction is significantly associated with organizational commitment, turnover intention, organizational citizenship behavior, and police performance among Korean police officers. The mean effect size was highest for organizational commitment (r = .566), followed by organizational citizenship behavior (r = .541), turnover intention (r = −.470), and police performance (r = .430). To explore potential moderating effects, age and sex were included as moderators; however, meta-regression analyses revealed that neither age nor sex significantly moderated the relationships between job satisfaction and organizational commitment or between job satisfaction and turnover intention. These findings suggest that job satisfaction is closely related to important organizational outcomes in the Korean police and highlight the value of considering job satisfaction in efforts to improve organizational effectiveness. Based on the empirical findings, this study proposes several managerial implications, acknowledges its limitations, and offers directions for future research.
