[Study on the current status and relationship between psychological capital and compassion fatigue with work engagement of clinical nurses]

Objective: To explore the relationship between clinical nurses' psychological capital, compassion fatigue with work engagement, and analyze the mediating effect of psychological capital between compassion fatigue and work engagement, so as to provide scientific evidence for reducing compassion fatigue and improving work engagement of clinical nurses. Methods: From December 2021 to February 2022, 494 clinical nurses from 7 general hospitals in Sichuan Province were selected for the study using convenience sampling. The General Information Questionnaire, the Compassion Fatigue Short Scale, the Work Engagement Short Scale and the Psychological Capital Questionnaire for Nurses were used to conduct the survey. Pearson correlation was used to analyze the correlation between compassion fatigue, work engagement and psychological capital. And stepwise regression analysis and Bootstrap method were used to analyze the effects of compassion fatigue and psychological capital on work engagement as well as the mediating effect of psychological capital between compassion fatigue and work engagement. Results: Of the 494 clinical nurses, 33 (6.7%) were male and 461 (93.3%) were female, with an average age of (31.47±6.89) years old and an average working years (9.87±7.61) years. The average scores of psychological capital, compassion fatigue and work engagement of clinical nurses were (5.01±0.76), (3.19±2.08) and (4.60±1.37) points, respectively. Compassion fatigue was negatively correlated with psychological capital and work engagement (r=-0.608, -0.580, P<0.001), and work engagement was positively correlated with psychological capital (r=0.771, P<0.001). Compassion fatigue and psychological capital together accounted for 61.3% of the variation in work engagement, with the direct effects on work engagement were -0.206 (95%CI: -0.283--0.138, P<0.001) and 0.677 (95%CI: 0.599-0.744, P=0.001), respectively. Psychological capital partially mediated the relationship between compassion fatigue and work engagement, with a mediating effect of -0.397 (95%CI: -0.456--0.340, P<0.001), accounting for 65.8% of the total effect. Conclusion: The work engagement of clinical nurses is at a high level. Managers should take targeted measures to alleviate the symptoms of clinical nurses' compassion fatigue, improve their psychological capital, and then stabilize and improve their level of work engagement.
