摘要

Non-suicidal self-injury (NSSI) is prevalent among early adolescents. However, few studies have explored the complex psychosocial mechanisms underlying NSSI among this population. This study aimed to examine the roles of Internet gaming disorder (IGD) and peer victimization by linking emotional insecurity to NSSI during early adolescence. Data were collected from 886 adolescents across four primary schools at three time points, spaced six months apart, using multi-stage random sampling. All participants were of Han ethnicity, with a mean age of 10.17 years. Girls accounted for 47.4% of the sample. The results indicated that IGD served as a mediator in the relationship between emotional insecurity and adolescent NSSI. Furthermore, this indirect effect was significantly moderated by peer victimization, such that the mediating role of IGD was only significant among adolescents experiencing high levels of peer victimization. These findings emphasized the longitudinal pathways through which emotional insecurity contributes to NSSI and have important implications for prevention and intervention strategies targeting NSSI among early adolescents.
