Research on mediating role of family function and depression emotion on resilience and PTSD in parents of children with cancer

目的探讨癌症儿童父母心理韧性与创伤后应激障碍(PTSD)的关系及家庭功能与抑郁情绪的链式中介效应。方法采用中文版PTSD平民版筛查问卷、Connor-Davidson韧性量表、家庭功能评定量表及抑郁量表对广州市4所三甲医院279例癌症儿童父母进行问卷调查,并应用相关性分析和结构方程建模分析心理韧性、家庭功能、抑郁情绪和创伤后应激障碍的关系。结果心理韧性、抑郁情绪、家庭功能对PTSD的直接效应系数分别为-0.033、0.772、0.130;模型的各路径效应大小及效应比例显示,心理韧性对PTSD总的效应为-0.243,心理韧性对PTSD总的间接效应为-0.210,占总体效应的86.42%。家庭功能在心理韧性和PTSD之间的效应值为-0.040,占总体效应的16.50%,抑郁情绪在心理韧性和PTSD之间的效应值为-0.117,占总体效应的48.10%。家庭功能和抑郁情绪在心理韧性和PTSD之间的链式中介效应值为0.053,占总体效应的21.80%。结论心理韧性通过家庭功能和抑郁情绪的链式中介作用对癌症儿童父母PTSD产生影响。

Objective To explore the relationship between the psychological resilience and posttraumatic stress disorder(PTSD)in the parents of children with cancer and the chain mediating effect of family functioning and depression emotion.Methods A total of 279 parents of children with cancer in four class 3A hospitals in Guangzhou City conducted the questionnaire survey by adopting the Chinese version of the PTSD Checklist-Civilian Version,Connor-Davidson Resilience Scale,General Functioning Sub-scale of McMaster Family Assessment Device and Patient Health Questionnaire Depression Scale.The correlation analysis and structural equation modeling were used to analyze the relationship among psychological resilience,family function,depression emotion and PTSD.Results The direct effect coefficients of psychological resilience,depression emotion and family function on PTSD were-0.033,0.772 and 0.130 respectively;The size and proportion of each path effect in the model showed that the total effect of psychological resilience on PTSD was-0.243,and the indirect effect of psychological resilience on PTSD was-0.210,accounting for 86.42%of the total effect.The effect value of family function between psychological resilience and PTSD was-0.040,accounting for 16.50%of the overall effect,and the effect value of depression emotion between mental resilience and PTSD was-0.117,accounting for 48.10%of the overall effect.The chain intermediary effect value of family function and depression between mental resilience and PTSD was 0.053,accounting for 21.80%of the overall effect.Conclusion The psychological resilience affects PTSD in the parents of children with cancer through the chain mediation of family functioning and depression mood.
