Regression analysis reveals school maladjustment increases non-suicidal self-injury in adolescents, indicating anxiety's role is moderated by single-parent family status.
Background: This study examines the influence of school maladjustment on non-suicidal self-injury among adolescents and the moderated mediating effect of anxiety according to single-parent family status.Methods: Regression analyses were performed using raw data from a survey of teenagers’ mental health and the PROCESS Macro method.Results: Adolescents’ school maladjustment had a positive effect on non-suicidal self-injury. In addition, the partial mediating effect of anxiety was confirmed. In other words, adolescents’ level of school maladjustment increased their level of anxiety, which in turn increased the likelihood of non-suicidal self-injurious behavior. Furthermore, the mediating effect of anxiety was moderated by single-parent family status. Specifically, the mediating effect of school maladjustment leading on non-suicidal self-injury through anxiety was more pronounced among adolescents from single-parent families than those from two-parent families.Conclusions: Intervention plans to deal with school maladjustment and anxiety among adolescents are proposed based on these findings.
