To explore the complex relationships among non-suicidal self-injury, depression and anxiety symptoms in adolescents, identify key symptoms and provide a theoretical foundation for targeted interventions.
A cross-sectional study.
In total, 1126 adolescents from a tertiary hospital in Shandong Province were assessed using the Adolescent Self-Injury Questionnaire, Patient Health Questionnaire and Generalised Anxiety Disorder Scale. Network analysis was employed to construct symptom networks and identify central and bridging symptoms.
The network analysis revealed that nodes GAD5 (Restlessness), GAD2 (Uncontrollable worry), and GAD4 (Trouble relaxing) exhibited the highest centrality indices, establishing them as core symptoms within the overall symptom network. The highest bridge intensity nodes were GAD1 (Nervousness), GAD5 (Restlessness) and non-suicidal self-injury.
By accurately identifying core and bridging symptoms, a scientific foundation is provided for developing precise and effective symptom management plans.
The study identified the most influential nodes in anxiety and depression among adolescents with non-suicidal self-injury. The findings would help in carrying out personalised and precise interventions to reduce non-suicidal self-injury occurrence and alleviate anxiety and depression symptoms among adolescents.

探讨青少年非自杀性自伤、抑郁和焦虑症状之间的复杂关系，识别关键症状，并为针对性干预提供理论基础。
一项横断面研究。
使用青少年自伤问卷、患者健康问卷和广泛性焦虑障碍量表对山东省一家三级医院的1126名青少年进行评估。采用网络分析构建症状网络并识别中心症状和桥梁症状。
网络分析显示，节点GAD5（坐立不安）、GAD2（无法控制的担忧）和GAD4（难以放松）表现出最高的中心性指数，使其成为整体症状网络中的核心症状。桥梁强度最高的节点是GAD1（紧张）、GAD5（坐立不安）和非自杀性自伤。
通过准确识别核心症状和桥梁症状，为制定精确有效的症状管理计划提供了科学依据。
该研究确定了非自杀性自伤青少年中焦虑和抑郁方面最具影响力的节点。这些发现将有助于开展个性化和精准干预，以减少非自杀性自伤的发生，并减轻青少年的焦虑和抑郁症状。
本研究遵循STROBE报告指南。
