Peer victimization and adolescent problematic social media use: The mediating role of psychological insecurity and the moderating role of family support

Peer victimization is a serious risk factor for the development of problematic social media use (PSMU) among adolescents. However, little is known about the mediating and moderating mechanisms underlying this associ-ation. The current study tested whether psychological insecurity mediated the relation between peer victimi-zation and PSMU, and whether this mediating process was moderated by family support among adolescents. A large sample of 1506 Chinese adolescents (Mage = 13.74 years, SD = 0.98) completed self-report measures regarding peer victimization, psychological insecurity, family support, and PSMU. After controlling for age, gender, and family economic status, results indicated that increased peer victimization was associated with higher psychological insecurity, which in turn predicted a greater incidence of PSMU. Moreover, family support moderated the first part of the mediation process, such that the relation between peer victimization and psy-chological insecurity was exacerbated for adolescents with high family support. This study advanced the current understanding of the mediating and moderating mechanisms associating peer victimization with PSMU among adolescents.
