青少年自伤行为的机制及影响因素:基于情绪管理的视角

青少年是自伤的高危人群，这与自伤的情绪管理功能密切相关。基于情绪管理视角，生物社会模型、回避体验模型和情绪管理模型分别从不同侧面揭示了情绪管理在自伤发生中的核心地位。综合目前关于自伤的心理学及跨学科研究成果发现，青少年自伤的影响因素主要包括基因与脑等生物学因素、家庭与学校环境中的人际因素，以及个体的人格特征。其中，基因、脑与家庭环境对青少年自伤的影响尤为关键。今后应在纵向研究、基因与环境交互作用以及脑成像技术融合等方面对自伤进行进一步探讨。

The Psychological Mechanism and Influential Factors of Adolescent NSSI: An Emotion Regulation Perspective

Adolescents is at high risk of non-suicidal self-injury (NSSI), which is closely related to the emotion regulation function of NSSI. Several explanatory models, including the biosocial model, experiential avoidance model and emotion regulation model, were put forward to enhance our understanding of the central role of emotion regulation in the onset and maintenance of NSSI. In this review, several risk factors related to emotion have been discussed, including biological factors, interpersonal factors and personality traits. Future research should focus on the longitudinal study, the interaction between gene and environment and the application of brain imaging technique.
