Analysis of the mediating effect of psychological resilience between Type D personality and post-traumatic stress disorder in emergency nurses

Abstract

Abstract: Objective To investigate the current status of Type D personality,psychological resilience and post-traumatic stress disorder（PTSD） among emergency nurses,analyze their correlations,and verify the mediating role of psychological resilience between Type D personality and PTSD. Methods Using convenience sampling method,240 emergency nurses in four grade-A tertiary general hospitals in Haikou City were surveyed by the general information questionnaire,Type D personality scale-14,psychological resilience scale,and the civilian version of the post-traumatic stress disorder scale from September to December 2023. Descriptive analysis,univariate analysis,correlation analysis and multiple linear stepwise regression analysis were used to analyze related influencing factors. AMOS 26.0 software was used to establish a structural equation model,and the mediating role of psychological resilience on the relationship between Type D personality and PTSD was analyzed by the Bootstrap test. Results The total score of Type D personality among emergency nurses was （19.94±12.02）points,the total score of psychological resilience was （59.35±12.06）points,and the total score of PTSD was （29.65±7.99）points. Correlation analysis showed that Type D personality was negatively correlated with psychological resilience（r=-0.265--0.523,all P<0.01） and positively correlated with PTSD（r=0.444-0.685,all P<0.01）. Psychological resilience was negatively correlated with PTSD（r=-0.327--0.676,all P<0.01）. Multiple linear stepwise regression analysis showed that Type D personality and psychological resilience were influencing factors of PTSD in emergency nurses（both P<0.01）. Psychological resilience played a partial mediating role between Type D personality and PTSD,and the mediating effect accounted for 40.44% of the total effect. Conclusion The Type D personality of emergency nurses in grade-A tertiary general hospitals in Haikou not only has a direct impact on PTSD,but can also have an indirect impact on PTSD through psychological resilience. Nursing managers can carry out interventions targeting Type D personality and psychological resilience,so as to effectively prevent and improve PTSD among emergency nurses.
