Network Analysis of the Associated Factors of Non‐Suicidal Self‐Injury Among Chinese Vocational High School Students From a Multi‐Theoretical Perspective

ABSTRACT The incidence of non‐suicidal self‐injury among Chinese vocational high school students is higher than in regular high school students. However, research on the factors associated with self‐injury in this specific population remains limited. To address this, we created a network structure of self‐injury among vocational students using network analysis methods grounded in multiple theoretical perspectives. This study included 1350 Chinese vocational students (55.48% males), with an average age of 16.26 years (SD = 0.87). Depression and anxiety were the most central nodes in the self‐injury network. Positive expectations of self‐injury outcomes, peer victimization, anxiety, and depression were significantly positively associated with self‐injury. Parental autonomy support was negatively associated, especially in females. These findings highlight the need for targeted prevention and intervention strategies.
