Patient mistreatment, emotional exhaustion and work-family conflict among nurses: a moderated mediation model of social sharing of negative work events and perceived organizational support.

Background: Nursing literature suggested that patient mistreatment has significant impacts on nurses' emotions and job burnout. Yet, further research is needed to understand the underlying mechanism and the spillover effect on nurses' families. Leveraging the goal progress theory, this study aimed to examine the association between patient mistreatment, nurses' emotional exhaustion, and work-family conflict, as well as the mediating role of social sharing of negative work events and the moderating role of perceived organizational support.

Methods: During the COVID-19 pandemic in China, a cross-sectional study was conducted with a sample of 1627 nurses from the Hematology Specialist Alliance of Chongqing from October to November 2022. Questionnaires were administered to measure patient mistreatment, perceived organizational support, social sharing of negative work events, emotional exhaustion, and work-family conflict. Hierarchical linear regression and conditional processes were used for statistical analyses.

Results: Patient mistreatment was positively associated with emotional exhaustion (β = 0.354, p < 0.001) and work-family conflict (β = 0.314, p < 0.001). Social sharing of negative work events played a partial mediating role in the relationship between patient mistreatment and emotional exhaustion (effect = 0.067, SE = 0.013), and work-family conflict (effect = 0.077, SE = 0.014). Moderated mediation analysis found that the mediation effect was stronger when the perceived organizational support was high.

Conclusion: Our findings reveal the amplifying effect of social sharing of negative work events on nurses' emotional exhaustion and work-family conflict. Perceived organizational support strengthens the positive effect of patient mistreatment on the social sharing of negative work events, thus resulting in increased emotional exhaustion and work-family conflict. We also discuss practical implications, limitations, and directions for future research.
