Purpose This study investigated the influence of organizational justice on junior nursing officers’ intent to stay in their positions and explored the mediating roles of job satisfaction and organizational commitment. Methods: A descriptive correlational design was employed, and data were analyzed using SPSS 29.0 software. Statistical analyses included descriptive statistics, the t-test, one-way analysis of variance, Pearson’s correlation coefficients, and multiple linear regression. The mediating effects of job satisfaction and organizational commitment were evaluated following Baron and Kenny’s three-step mediation procedure, and significance was confirmed through the bootstrapping method. Results: Organizational justice, job satisfaction, organizational commitment, and intent to stay were all significantly positively correlated. The mediating effects of job satisfaction and organizational commitment on the relationship between organizational justice and intent to stay were confirmed. Conclusion: Based on the findings of this study, job satisfaction and organizational commitment were found to fully mediate the relationship between organizational justice and intent to stay. Therefore, to enhance the intent to stay among junior nursing officers, it is considered necessary to develop supportive measures and establish systems within the military and nursing corps that strengthen organizational justice for junior nursing officers.
