儿童期虐待对大学生自伤行为的影响：抑郁的中介作用及性别差异

The Influence of Childhood Abuse on Self-Harm Behaviors in a Sample of Undergraduates: Mediating Effect of Depression and Its Gender Difference

摘要: 为考察抑郁在儿童期虐待与自伤行为之间的中介作用及其性别差异，本研究采用儿童期虐待问卷、流调中心抑郁量表和青少年自我伤害行为量表在线调查了312名本科生。结果发现：1) 儿童期虐待、抑郁和自伤行为呈显著正相关；2) 在总样本中，儿童期虐待、抑郁正向预测自伤行为，抑郁在二者间起部分中介作用；3) 区分群组，抑郁的中介效应在男、女生中均不显著，儿童期虐待对自伤行为的路径系数存在显著性别差异。研究结果提示：儿童期虐待、抑郁和自伤行为密切联系，三者间的相互作用机制存在性别差异。今后研究需就变量间的相互作用机制及性别差异做进一步验证，这对自伤行为的预防和干预具有重要指导意义。

Abstract: This study examined the mediating role of depression in the association of childhood abuse and self-injuries. Moreover, the gender difference in this hypothesized mediating model was also tested. A total of 312 undergraduate students were invited to fill out a questionnaire which in-cluding the Chinese Version of Childhood Trauma Questionnaire, the Center for Epidemiologic Studies-Depression Scale and the Adolescents Self-Harm Scale online. This study found that: 1) Childhood abuse was positively correlated with depression and self-harm behaviors. 2) For the entire study sample, childhood abuse and depression positively predict self-harm behaviors, and the depression is a partial mediator between childhood abuse and self-harm behaviors. 3) When grouped by gender, the mediating effect of depression was not significant in males or females, and the path coefficients from childhood abuse and self-harm behaviors were significantly different between males and females. Based on these findings, we suggested that childhood abuse, depression and self-harm behaviors were closely associated. The interaction mechanism of three study variables was significantly different between males and females. Future studies need to explore the potential interaction mechanism among these variables and their gender difference, which is of great significance for intervention.
