未成年犯童年期受虐待程度与攻击行为的关系：有调节的中介模型

采用问卷法对广东省未成年犯管教所417名男性未成年犯进行调查，考察了自尊在未成年犯童年期受虐待程度与其攻击行为关系间的中介效应，以及感觉寻求在其中的调节作用。结果发现：（1）在控制了年龄、家庭月收入和父母受教育水平后，童年期受虐待程度可显著正向预测攻击行为；（2）自尊在童年期受虐待程度与攻击行为之间起部分中介作用；（3）感觉寻求显著调节自尊对攻击行为的影响，间接效应对于低感觉寻求的个体不显著，对于高感觉寻求的个体显著。

The Relationship Between Childhood Trauma and Aggressive Behavior Among Juvenile Delinquents: A Moderated Mediation Model

The present study aimed to explain the association between childhood trauma and aggressive behavior among juvenile delinquents by investigating the mediating role of self-esteem and the moderating role of sensation seeking. A total of 458 juvenile delinquents in Guangdong juvenile delinquency management institutes participated in the questionnaire survey. The results showed that: 1) by controlling gender, age, family monthly income, and parents’ education level, childhood trauma could positively predict aggressive behavior; 2) self-esteem partially mediated the relationship between childhood trauma and aggressive behavior; 3) the indirect effect of childhood trauma on aggressive behavior through self-esteem was moderated by sensation seeking. Specifically, the indirect effect was significant among juvenile delinquents with high sensation seeking, while the effect among those with low sensation seeking was nonsignificant. The present study can be beneficial to our understanding of key mechanisms underlying the association between childhood trauma and aggressive behavior among juvenile delinquents.
