Published online September 30, 2025; DOI: https://doi.org/10.17547/kjsr.2025.33.3.155

Abstract PDF: 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.

Abstract PDF: Background
This study investigated the influence of parenting stress among single parents on the level of Internet addiction in their adolescent children, while also considering the moderating effect of family economic status.
Methods
An analysis was conducted using regression models to assess direct and moderating effects, utilizing data from the 2021 Survey of Single-parent Families, focusing on single parents with adolescent children.
Results
It was observed that single parents’ parenting stress had a positive and significant influence on the level of Internet addiction seen in their adolescent children. Furthermore, this influence was observed to be even stronger when the family’s economic status was lower.
Conclusions
This study empirically examined the influence of parenting and economic circumstances on the level of Internet addiction among adolescent children in single-parent families, drawing on nationally representative data. The study also underscored the need for diverse intervention strategies.
