Nonsuicidal self-injury (NSSI) refers to the direct, deliberate infliction of harm to one's body tissue without the intention to die. The prevalence of NSSI has increased significantly globally in recent years and has become an important public health problem affecting the health of people, especially adolescents. The occurrence of NSSI in adolescents is the result of the interaction of different factors. Many scholars have proposed various theoretical models to explain the mechanism of NSSI behavior based on previous research on the influencing factors of NSSI. Moreover, advances have been made in genetic and neuroimaging mechanisms related to NSSI. Understanding the genetic and neuroimaging mechanisms of NSSI is important for both describing and treating the disorder. This literature review discusses the progress made on the risk factors, theoretical models, and biological mechanisms of NSSI.
非自杀性自伤（NSSI）是指直接、故意地对自己的身体组织造成伤害，且没有死亡意图。近年来，NSSI在全球的患病率显著上升，已成为影响人们尤其是青少年健康的一个重要公共卫生问题。青少年NSSI的发生是多种不同因素相互作用的结果。许多学者在前人对NSSI影响因素研究的基础上，提出了各种理论模型来解释NSSI行为的机制。此外，与NSSI相关的遗传和神经影像学机制也取得了进展。了解NSSI的遗传和神经影像学机制对于描述和治疗该疾病都很重要。这篇文献综述讨论了NSSI在危险因素、理论模型和生物学机制方面取得的进展。
