创伤暴露对青少年暴力行为和自杀意念的影响:创伤后应激障碍和抑郁的中介作用

Posttraumatic Stress Disorder and Depression Mediates the Relationship between Traumatic Exposure and Violent Behavior/Suicidal Ideation in Adolescents After an Earthquake

采用创伤暴露问卷、基于DSM-5的创伤后应激障碍症状核查表、流调中心用抑郁量表和青少年行为问题调查表,在雅安地震3.5年后对地震极重灾区的703名中学生进行调查,考察创伤暴露对暴力行为和自杀意念的影响,并检验创伤后应激障碍和抑郁在其中的中介作用。结果发现:创伤暴露可以直接正向预测暴力行为和自杀意念,PTSD在创伤暴露对暴力行为和自杀意念的影响间起中介作用,抑郁仅在创伤暴露对自杀意念的影响间起中介作用,而在创伤暴露对暴力行为影响间的中介效应不显著。

To explore the mediating effect of posttraumatic stress disorder(PTSD)and depression in the relationship between traumatic exposure and violent behavior,suicidal ideation among adolescents after the Ya’an earthquake.All adolescents completed the Trauma exposure questionnaire,PTSD checklist for DSM-5,the Center for Epidemiologic Studies Depression Scale for Children and the Child Behavior Problems Questionnaire.The results indicated that traumatic exposure directly and positively predicted violent behaviors and suicidal ideation.Moreover,traumatic exposure positively predicted violent behavior and suicidal ideation via PTSD,and traumatic exposure positively predicted suicidal ideation but not violent behavior via depression.This study suggests that traumatic exposure is one of the risk factors for suicidal ideation and violent behavior among adolescents after the earthquake.PTSD and depression played an important role to mediate the effect of traumatic exposure on suicidal ideation and violent behavior.
