To explore the relationship between non-suicidal self-injury and suicidal ideation in adolescents and examine the roles of rumination and decentering in that relationship.
By means of a questionnaire, 175 adolescent patients in a psychiatric hospital in Fujian Province were given the Functional Assessment of Self-Mutilation: Chinese Version, Positive and Negative Suicide Ideation, Ruminative Response Scale: Chinese Version, and Experiences Questionnaire: Decentering Scale.
(1) Adolescent non-suicidal self-injury was significantly positively related to suicidal ideation and rumination and significantly negatively related to decentering. Suicidal ideation was significantly positively related to rumination and significantly negatively related to decentering. Rumination was significantly negatively related to decentering. (2) Rumination and decentering played a complete chain-mediating role between non-suicidal self-injury and suicidal ideation. Non-suicidal self-injury was found to indirectly affect suicidal ideation along three pathways: the independent mediating role of rumination (the mediating effect accounted for 40.166%), independent mediating role of decentering (the mediating effect accounted for 41.274%), and chain-mediating role of rumination and decentering (the mediating effect accounted for 14.958%).
Adolescent non-suicidal self-injury can indirectly affect suicidal ideation through rumination and decentering. In the future, mindfulness and other methods should be used to improve individuals' levels of decentering and cultivate emotional regulation abilities, so as to reduce the incidence of non-suicidal self-injury and suicide in adolescents.
探讨青少年非自杀性自伤与自杀意念之间的关系，并检验沉思和去中心化在该关系中的作用。
通过问卷调查，对福建省某精神病院的175名青少年患者进行了自残功能评估：中文版、正负性自杀意念、沉思反应量表：中文版和体验问卷：去中心化量表的测评。
（1）青少年非自杀性自伤与自杀意念和沉思显著正相关，与去中心化显著负相关。自杀意念与沉思显著正相关，与去中心化显著负相关。沉思与去中心化显著负相关。（2）沉思和去中心化在非自杀性自伤与自杀意念之间起完全链式中介作用。非自杀性自伤通过三条途径间接影响自杀意念：沉思的独立中介作用（中介效应占40.166%）、去中心化的独立中介作用（中介效应占41.274%）以及沉思和去中心化的链式中介作用（中介效应占14.958%）。
青少年非自杀性自伤可通过沉思和去中心化间接影响自杀意念。未来应采用正念等方法提高个体的去中心化水平，培养情绪调节能力，以降低青少年非自杀性自伤和自杀的发生率。
