This study examined the effect of adolescents’ perceived negative parenting on nonsuicidal self-injury (NSSI) and tested the sequential mediating roles of resilience and SNS addiction tendency in this relationship. A survey was conducted with 177 middle school students (8th–9th grade) across South Korea. Descriptive statistics, correlation analyses, and a multiple mediation model were employed to analyze the data. The results indicated that negative parenting significantly reduced resilience, and lower resilience was associated with higher levels of SNS addiction tendency. In turn, SNS addiction tendency significantly predicted NSSI. Although the direct effect of negative parenting on NSSI was not significant, the indirect effect through SNS addiction tendency was significant. Furthermore, the sequential mediation pathway—from negative parenting to decreased resilience, which then increased SNS addiction tendency, ultimately leading to higher NSSI—was also confirmed. In contrast, the single mediation effect of resilience alone was not significant. These findings suggest that negative parenting environments may weaken adolescents’ emotional protective resources, such as resilience, and that heightened reliance on SNS-based emotional regulation can increase vulnerability to self-injurious behaviors. Therefore, prevention and intervention efforts targeting adolescent NSSI should incorporate strategies that enhance emotional responsiveness in parent–child relationships, strengthen resilience, and reduce dependence on SNS-mediated emotional regulation through digital literacy education.
