Abstract
Burnout among nurses is a pervasive concern in healthcare, with profound implications for patient care and nurse well-being. While research has highlighted the detrimental effects of burnout on many aspects of nursing, including patient safety and quality of care, the underlying mechanisms driving burnout warrant further investigation. In this cross-sectional study, we surveyed 196 nurses from diverse Italian hospitals using an online questionnaire via Qualtrics. Our findings revealed significant negative correlations between psychological safety climate and both relational stressors and emotional exhaustion. Conversely, relational stressors positively correlated with emotional exhaustion, and a significant negative indirect effect of psychological safety climate was found for emotional exhaustion through relational stressors, emphasizing the pivotal role of psychological safety climate in mitigating nurse burnout. Our study underscores the potential effectiveness of interventions targeting psychological safety climate and relational stressors in alleviating emotional exhaustion and burnout among nurses. Theoretical implications underscore the importance of deepening the role of psychological safety climate in mitigating emotional exhaustion, while practical implications emphasize the need for fostering a positive psychological safety climate and implementing targeted interventions to support nurses' well-being.
