Outline
To explore the relationship between family functioning and non-suicidal self-injury (NSSI) among adolescents in a specific western region of China, and to examine the chain mediating role of internet addiction and depression in this relationship.
A cross-sectional study was conducted among 1 331 seventh and eighth-grade students from a middle school in a western region of China. Assessments were carried out using the Internet Addiction Test (IAT), the Center for Epidemiological Studies Depression Scale for Children (CES-DC), the Chinese version of the Family Assessment Instrument (C-FAI), and the Deliberate Self-Harm Inventory (DSHI).
The detection rate of NSSI among adolescents was 32.5%. Statistically significant differences in NSSI were found across gender (χ2=39.539), history of smoking (χ2=29.838), history of alcohol use (χ2=35.042), academic burden (χ2=49.824), and sleep duration (χ2=54.838), with all P<0.001. Mediation analysis indicated that family dysfunction not only directly influenced NSSI but also exerted indirect effects through three pathways: internet addiction alone (accounting for 13.2%), depression alone (accounting for 39.7%), and the sequential chain of internet addiction followed by depression (accounting for 7.4%). The total indirect effect accounted for 58.8% of the overall influence.
Family dysfunction is a significant risk factor for adolescent NSSI in the studied region. Its mechanism of action involves exerting influence through the chain mediating effects of internet addiction and depression. Interventions aimed at improving family functioning, promoting healthy internet use habits, and addressing depressive symptoms may help reduce the risk of NSSI among adolescents.
