Adolescents often experience negative emotions, such as depression and anxiety, due to rapid biological, cognitive, and social changes during this developmental stage. In recent years, the non-suicidal self-injury (NSSI) among adolescents with Major Depressive Disorder (MDD) has garnered increasing attention, with rumination identified as a significant risk factor for its occurrence. This study established a moderated mediation model to examine the impact of rumination on NSSI among adolescents with MDD and its underlying mechanisms. The final research sample consisted of 1,601 adolescents with MDD (18.2% males, mean age = 14.85 years, SD = 1.65) from 14 psychiatric/general hospitals across nine provinces in China. Participants completed self-report questionnaires assessing NSSI, rumination, loneliness, and resilience. Results indicated that rumination contribute to NSSI via loneliness during adolescence, whereas resilience may buffer the adverse effects of rumination on NSSI, implying the potential effectiveness of reducing loneliness and promoting resilience in the intervention and prevention of NSSI. These findings further illuminate the mechanisms underlying the development of NSSI, aiding in its prediction and prevention among adolescents, thereby assisting them in better coping with emotional and behavioral developmental challenges during adolescence.
青少年在这一发育阶段，由于生物、认知和社会的快速变化，常常会经历抑郁和焦虑等负面情绪。近年来，重度抑郁症（MDD）青少年中的非自杀性自伤行为（NSSI）越来越受到关注，反复思考被确定为其发生的一个重要风险因素。本研究建立了一个有调节的中介模型，以检验反复思考对MDD青少年NSSI的影响及其潜在机制。最终的研究样本包括来自中国九个省份14家精神病院/综合医院的1601名MDD青少年（男性占18.2%，平均年龄 = 14.85岁，标准差 = 1.65）。参与者完成了评估NSSI、反复思考、孤独感和心理韧性的自陈问卷。结果表明，在青少年时期，反复思考通过孤独感导致NSSI，而心理韧性可能缓冲反复思考对NSSI的不利影响，这意味着在干预和预防NSSI方面，减少孤独感和提高心理韧性可能有效。这些发现进一步阐明了NSSI发展的潜在机制，有助于对青少年NSSI进行预测和预防，从而帮助他们更好地应对青少年时期的情绪和行为发展挑战。
