负性生活事件对初中生自我伤害行为的影响:有调节的中介效应
The Relationship between Negative Life Events and Non-suicidal Self-injury among Junior Middle School Students: Moderated Mediation Effect

采用负性生活事件量表、自我批评量表、亲子关系量表和青少年自我伤害行为问卷对333名初中生进行测查，探讨负性生活事件对初中生自我伤害行为的影响及作用机制。结果表明：（1）负性生活事件对初中生的自我批评和自我伤害行为均有显著的正向预测作用；（2）自我批评在负性生活事件与初中生自我伤害行为之间起着部分中介作用；（3）负性生活事件和自我批评的关系（中介效应的前半段路径）受到亲子关系的调节，即负性生活事件对自我批评的正向影响随着父子关系和母子关系的增强而减弱。因此，负性生活事件和初中生自我伤害行为之间存在有调节的中介效应。
To investigate the impact of negative life events on the non-suicidal self-injury behavior, 333 junior middle school students were recruited to participate in this study, and they anonymously filled out questionnaires regarding negative life events, self-criticism, parent-child relationship and non-suicidal self-injury behavior. This study indicated that:(1) negative life events had a significantly positive prediction for self-criticism and self-injury behavior of the junior middle school students; (2) self-criticism of junior middle school students mediated the relationship between negative life events and their self-injury; (3) the relationship between life events and their self-criticism was moderated by parent-child relationship. That is, with father-child relationship and mother-child relationship being strengthen, the influence of negative life events on the self-criticism of the junior middle school students was decreased. Therefore, there was a moderated mediation model between negative life events and self-injury, and the present study enriched the theory of non-suicidal self-injury behavior.
