Compassion fatigue

This study aimed to determine the mediating role of ambiguity intolerance and worry in the relationship between resilience and fatigue compassion in nurses. The research method employed a descriptive-correlational design, and the statistical population of this study consisted of all nurses working in hospitals in Tehran Province in 2024. A convenience sampling method was used to select 220 nurses from this population. The study tools were included Connor-Davidson Resilience Scale (2003), the Compassion Fatigue Inventory by Saberi et al. (2017), Penn State Worry Questionnaire by Meyer et al. (1990), and the Ambiguity Tolerance Scale-II by McLain (2009). Structural equation modeling was used to analyze the data. The results showed that worry mediates the relationship between resilience and fatigue compassion negatively and significantly (β=-0.096, P=0.001). Ambiguity intolerance mediates the relationship between resilience and fatigue compassion negatively and significantly (β=-0.050, P=0.029). Based on the results of the present study, it seems that the lack of resilience among nurses in ambiguous and worrying situations causes burnout and fatigue compassion.
