Non-suicidal self-injury (NSSI) is a serious public health problem that can lead to adverse effects such as cognitive impairment, poor interpersonal relationships and violent crime. The progress of preventing and treating NSSI in adolescents depends on other changeable risk factors, such as negative mood, sleep, and diet habits. However, the risk factors for adolescent NSSI remain unclear. Therefore, this study explores the key factors influencing adolescents' NSSI behavior through the use of network analysis.
The study recruited 4040 middle school students aged 12-18 years old. From November 1st, 2023 to January 1st, 2024, paper questionnaires were utilized to investigate the participants' basic conditions, negative mood, NSSI, sleep conditions, and diet habits. Network analysis was used to explore the interrelationship among risk factors and discover the core factor.
In the network structure of adolescents with NSSI behavior, the most correlated nodes were negative emotions (CDI2) and low self-esteem (CDI3). Compared with adolescents without NSSI behavior, adolescents with NSSI behavior showed prominent anxiety symptoms related to injury avoidance (MASC1) and social anxiety (MASC2). Anhedonia (CDI1) was both the central node and the bridge node of the network.
The cross-sectional design of this study couldn't clarify the causal inference between independent variables and results.
Anhedonia is the key factor affecting adolescents' emotion regulation. Furthermore, we hypothesize that adolescent NSSI is an emotional disorder, and anhedonia plays an important role in preventing and intervening in adolescents' NSSI behavior.
非自杀性自伤（NSSI）是一个严重的公共卫生问题，可能导致认知障碍、人际关系不佳和暴力犯罪等不良后果。青少年NSSI防治工作的进展取决于其他可变风险因素，如负面情绪、睡眠和饮食习惯。然而，青少年NSSI的风险因素仍不明确。因此，本研究通过网络分析探索影响青少年NSSI行为的关键因素。
本研究招募了4040名12至18岁的中学生。2023年11月1日至2024年1月1日，采用纸质问卷调查参与者的基本情况、负面情绪、NSSI、睡眠状况和饮食习惯。采用网络分析探讨风险因素之间的相互关系并发现核心因素。
在有NSSI行为的青少年网络结构中，相关性最高的节点是负面情绪（CDI2）和低自尊（CDI3）。与无NSSI行为的青少年相比，有NSSI行为的青少年在与回避伤害（MASC1）和社交焦虑（MASC2）相关的焦虑症状方面表现突出。快感缺失（CDI1）既是网络的中心节点也是桥梁节点。
本研究的横断面设计无法阐明自变量与结果之间的因果推断。
快感缺失是影响青少年情绪调节的关键因素。此外，我们假设青少年NSSI是一种情绪障碍，快感缺失在预防和干预青少年NSSI行为中起重要作用。
