국립대학 교직원의 공공봉사동기가 조직몰입에 미치는 영향: 직무만족의 매개효과와 고용형태의 조절효과 = The Effect of Public Service Motivation on Organizational Commitment among Employees in National Universities: The Mediating Role of Job Satisfaction and the Moderating Role of Employment Status

다국어 초록 (Multilingual Abstract)

This study examines the mechanism through which public service motivation (PSM) influences organizational commitment among employees in national universities, focusing on the mediating role of job satisfaction and the moderating role of employment status. While prior research has largely relied on between-sector comparisons (public vs. private), this study shifts attention to within-sector heterogeneity by investigating differences between civil servants and non-civil servant employees within the same public organization.
Using survey data collected from employees at a Korean national university (N = 111), structural equation modeling and multi-group analysis were employed to test the proposed moderated mediation model. The results indicate that PSM has a significant positive effect on both job satisfaction and organizational commitment in the full sample. Job satisfaction partially mediates the relationship between PSM and organizational commitment, suggesting that intrinsic public-oriented motivation translates into organizational attachment through positive job-related experiences.
Importantly, multi-group analysis reveals significant differences by employment status. Among civil servants, PSM significantly influences organizational commitment through job satisfaction, whereas the mediating pathway is not statistically significant among non-civil servant employees. The indirect effect differs significantly between the two groups, while the direct effect remains similar. These findings suggest that the mechanism linking PSM to organizational commitment is conditioned by institutional context, particularly differences in employment stability and relational psychological contracts.
By highlighting within-sector heterogeneity, this study extends existing PSM literature and underscores the importance of institutional position in shaping the attitudinal consequences of public service motivation. Practical implications for personnel management in national universities are discussed.
