【摘要】 目的 分析校园欺凌对青少年早期非自杀性自伤行为发展轨迹的影响，为预防青少年早期自伤行为提供依据。方法 采用校园欺凌问卷、青少年非自杀性自伤行为评定问卷分别于2023年3月、2023年9月、2024年3月对941名初一年级学生进行追踪调查；采用潜变量增长混合模型(LGMM)分析青少年早期非自杀性自伤行为发展轨迹的异质性，采用多分类logistic回归分析探究校园欺凌对非自杀性自伤行为发展轨迹异质性的影响。结果 LGMM结果显示，类别一为“低危缓解组”(占比87.35%),类别二为“中危恶化组”(占比7.23%);类别三为“高危恶化组”(占比5.42%);男生是“中危恶化组”(OR=0.369,95%CI=0.216～0.631)、“高危恶化组”(OR=0.325,95%CI=0.121～0.872)的保护因素，校园欺凌是“中危恶化组”(OR=1.375,95%CI=1.269～1.490)、“高危恶化组”(OR=1.520,95%CI=1.343～1.734)的危险因素。结论 青少年早期非自杀性自伤行为发展轨迹存在异质性，校园欺凌是青少年早期自伤行为的危险因素。更多还原

【Abstract】 Objective To analyze the influence of school bullying on the development track of adolescents’ early non-suicidal NSSI, and to provide evidence for the prevention of adolescents’ early NSSI. Methods A total of 941 first grade students were investigated in March 2023, September 2023 and March 2024 by using the School Bullying Questionnaire and the Adolescents’ Non-Suicidal Self-Injury Behavior Assessment Questionnaire(ANSAQ). The heterogeneity of the developmental trajectory of early non-suicidal NSSI was analyzed by the latent variable growth mixed model(LGMM), and the influence of school bullying on the heterogeneity of NSSI was explored by multiple logistic regression analysis. Results The LGMM results showed that class 1(Class1) was the “low-risk mitigation group”(87.35%) and class 2(Class2) was the “medium-risk stable group”(7.23%); Category 3(Class3) was the “high-risk deteriorating group”(5.42%); Male students were the protective factors in the “medium-risk stable group”(OR=0.369, 95%CI=0.216-0.631) and the “high-risk deteriorating group”(OR=0.325, 95%CI=0.121-0.872), and bullying was the protective factor in the “medium-risk stable group”(OR=1.375, 95%CI=1.269-1.490) and “high-risk worsening group”(OR=1.526, 95%CI=1.343-1.734). Conclusion The developmental trajectory of non-suicidal NSSI in early adolescents is heterogeneous, and school bullying is a risk factor for NSSI in early adolescents.更多还原
