The Mediating Role of Psychological Resilience in the Relationship Between Organizational Support and Change Fatigue Among Obstetric and Gynecological Nurses

Objective To explore the relationships among organizational support, psychological resilience, and change fatigue in obstetric and gynecological nurses, and to examine the mediating role of psychological resilience based on the Conservation of Resources theory. Methods A cross-sectional survey was conducted between January and March 2025 using convenience sampling. A total of 477 OB-GYN nurses from five provinces (including Shaanxi and Guangdong) completed a set of validated questionnaires, including a general information questionnaire, the Perceived Organizational Support Scale (POS), the Change Fatigue Scale (CFS), and the Connor-Davidson Resilience Scale (CD-RISC). Results The mean scores for organizational support, psychological resilience, and change fatigue were 48.41 ± 11.13, 87.13 ± 15.00, and 26.84 ± 8.24, respectively. Psychological resilience was negatively correlated with change fatigue ( r = − 0.316, p  < 0.01) and positively correlated with organizational support ( r  = 0.575, p  < 0.01). Organizational support was also negatively correlated with change fatigue ( r = − 0.379, p  < 0.01). Organizational support significantly predicted lower levels of change fatigue (total effect: β = − 0.387, p  < 0.001), with psychological resilience partially mediating this relationship (indirect effect: β = − 0.101, p  < 0.001), accounting for 26% of the total effect. Conclusion Psychological resilience partially mediates the relationship between organizational support and change fatigue among OB-GYN nurses. Nursing administrators should prioritize enhancing organizational support and strengthening nurses' psychological resilience to reduce change fatigue and improve adaptability during organizational transitions.
