Moral distress and compassion fatigue among nursing interns: a cross-sectional study on the mediating roles of moral resilience and professional identity

BACKGROUND: Nursing interns often faced moral distress in clinical practice, similar to registered nurses, which can lead to compassion fatigue. The roles of moral resilience and professional identity in influencing the psychological well-being of nursing interns are recognized, but the interrelationships among moral distress, moral resilience, professional identity, and compassion fatigue in this group remain unclear. OBJECTIVES: This study aimed to investigate the impact of moral distress on compassion fatigue among nursing interns and to explore the mediating role of moral resilience and professional identity. METHODS: A quantitative cross-sectional study was conducted with 467 nursing interns. Data were collected using Compassion Fatigue Short Scale, Moral Distress Scale-revised, Rushton Moral Resilience Scale, and Professional Identity Scale. Data analyses were performed using SPSS 22.0 and Amos 21.0, adhering to the STROBE statement. RESULTS: The mean scores for compassion fatigue, moral distress, moral resilience, and professional identity were 35.876, 44.887, 2.578, and 37.610, respectively. Moral distress was positively correlated with compassion fatigue. Structural equation modeling showed that moral resilience and professional identity partially mediated the relationship between moral distress and compassion fatigue (β = 0.448, P < 0.001). CONCLUSION: The findings suggest that moral distress directly influences compassion fatigue among nursing interns and also exerts an indirect effect through moral resilience and professional identity. Interventions aimed at enhancing moral resilience and fostering a strong professional identity may help mitigate the adverse effects of moral distress on compassion fatigue among nursing interns.
