Outline
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.
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.
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).
The developmental trajectory of non-suicidal NSSI in early adolescents is heterogeneous, and school bullying is a risk factor for NSSI in early adolescents.
