主观创伤暴露对疫情下青少年创伤后应激障碍的影响:有调节的中介效应

Effects of Subjective Trauma Exposure on Post-traumatic Stress Disorder in Adolescents During COVID-19 Outbreak: A Moderated Mediating Model

目的:了解新冠肺炎疫情下青少年的创伤后应激障碍症状(PTSD)流行程度及其影响机制。方法:以方便取样方式抽取重庆市某中学3441名学生填写主观创伤暴露问卷、自我表露问卷、家庭无效环境问卷和儿童创伤后应激障碍症状量表。结果:29.90%青少年有PTSD高风险症状;主观创伤暴露程度正向预测PTSD;自我表露是主观创伤暴露到PTSD的中介变量;家庭无效环境调节中介效应的后半段。结论:新冠肺炎疫情下主观创伤暴露可导致青少年PTSD症状,且主观创伤暴露对PTSD症状的影响通过自我表露的部分中介效应起作用。与高家庭无效环境个体相比,自我表露对低家庭无效环境的青少年PTSD症状缓解更快。

Objective: To investigate the prevalence rate and its mechanism of Post-traumatic Stress Disorder(PTSD) among adolescents during corona virus disease 2019(COVID-19) outbreak. Methods: 3441 middle school students from in Chongqing were selected by convenient sampling method to fill the Subjective Trauma Exposure Questionnaire, Child PTSD Symptom Scale, Family Invalidation Questionnaire and Distress Disclosure Index. Results: 29.90% of adolescents had high risk symptoms of PTSD;Subjective trauma exposure positively predicted PTSD;Self-disclosure was the mediating variable of subjective trauma exposure to PTSD;And family invalidation moderated the effect of self-disclosure to adolescent’s PTSD. Conclusion: Subjective trauma exposure can cause PTSD symptoms in adolescents through the mediation of selfdisclosure. Compared with individuals with high family invalidation, self-disclosure can relieve PTSD symptoms more quickly among adolescents with low family invalidation.
