Promoting nurses’ organizational commitment may help alleviate nursing shortage. This study sought to evaluate the relationships between organizational commitment, job satisfaction, organizational justice, and self-efficacy among nurses.   Materials & Methods: This cross-sectional study was conducted on 401 Iranian nurses randomly selected through two-stage cluster sampling. Data were collected using self-administered questionnaires and analyzed using the SPSS (v. 17.0) and the Amos (v. 17.0) software. Results: The goodness of fit indices were as the following: χ2/df = 2.76 (P < 0.001), GFI = 0.93; AGFI = 0.87, NFI = 0.96, RMSEA = 0.068, and CFI = 0.95. Organizational commitment had significant positive relationships with self-efficacy (β3 = 0.28, P < 0.001) and job satisfaction (γ3 = 0.73, P < 0.001), while organizational justice had significant positive relationship with job satisfaction (γ2 = 0.89, P < 0.001). Moreover, job satisfaction had a mediating role in the relationship of organizational justice with organizational commitment. Conclusion: Hospital managers can promote nurses’ organizational commitment through employing strategies to enhance their perceived organizational justice and thereby, improving their job satisfaction. https://npt.tums.ac.ir/index.php/npt/article/view/445 https://npt.tums.ac.ir/index.php/npt/article/download/445/404
