背景:非自杀性自我伤害(NSSI)是青少年重度抑郁症(MDD)的重要公共卫生问题。尽管之前的研究已经将虐待儿童(CM)与NSSI联系起来,确切的机制尚不清楚。本研究旨在调查CM,认知重估(CR),青少年MDD的消极应对方式(NC)和NSSI,从潜在变量理论和心理障碍网络理论的角度来看。
方法:从2023年1月至12月招募了651名患有MDD的青少年样本。CM上的数据,CR,NC,和NSSI是通过纸质自我报告问卷收集的。数据分析主要涉及结构方程建模和网络分析。
结果:青少年MDD患者NSSI报告率为48.2%。CM与NSSI呈显著正相关。NSSI通过三条路径受到CM的影响:CR的中介作用,NC的中介作用,以及CR和NC的链中介作用。情绪滥用(EA)是中心节点,而NSSI,EA,和“面对麻烦时安静哭泣的冲动”(NC10)是关键的桥梁节点。
结论:本研究首次使用结构方程模型和网络分析来探索CM之间的关系,CR,NC,青少年MDD的NSSI,为青少年MDD的早期预防和针对性干预提供理论依据。
BACKGROUND: Non-suicidal self-injury (NSSI) is a significant public health concern among adolescents with major depressive disorders (MDD). Although previous research has linked child maltreatment (CM) to NSSI, the precise mechanisms remain unclear. This study aims to investigate the association between CM, cognitive reappraisal (CR), negative coping styles (NC) and NSSI in adolescents with MDD, from the perspectives of both Latent Variable Theory and the Network Theory of Mental Disorder.
METHODS: A sample of 651 adolescents with MDD was recruited from January to December 2023. Data on CM, CR, NC, and NSSI were collected through paper-based self-reported questionnaires. Data analysis primarily involved structural equation modeling and network analysis.
RESULTS: The reporting rate of NSSI among adolescents with MDD was 48.2%. CM showed a significant positive correlation with NSSI. NSSI was affected by CM through three paths: the mediating role of CR, the mediating role of NC, and the chain mediating role of both CR and NC. Emotional abuse (EA) was the central node, while NSSI, EA, and \"The urge to cry quietly when faced with troubles\"(NC10) were the key bridge nodes.
CONCLUSIONS: This study is the first to use both structural equation modeling and network analysis to explore the explore the relationship between CM, CR, NC, and NSSI in adolescents with MDD, providing a theoretical basis for future early prevention and targeted interventions for adolescents with MDD.
