There has been growing concern over Internet gaming addiction (IGA) around the world. However, the risk factors and mediating mechanisms of IGA in Chinese youth remain largely unknown. A total of 323 Chinese adolescents (52.94% females, M age = 14.83, SD = 0.49, range = 13.50–16.50) completed questionnaires regarding peer victimization, deviant peer affiliation (DPA), normative beliefs about aggression (NBA), and IGA in the fall semester of 7th, 8th, and 9th grade. Structural equation modeling showed that 7th grade peer victimization predicted higher 8th grade DPA, which in turn was associated with enhanced 9th grade NBA, and ultimately, higher 9th grade IGA. In addition, 7th grade peer victimization made a unique contribution to 9th grade IGA through 9th grade NBA. The current study goes beyond previous research by using a 2-year longitudinal design and by taking into account both peer relations and individual cognitions as predictors of IGA. In addition, these findings have practical significance for improving intervention strategies targeting risk factors for adolescent IGA.

This study examined the mediating effect of school connectedness on the relationship between inter‐parental conflict and adolescent delinquency, and impulsivity's moderation of the conditional effect of school connectedness. In total, 1407 Chinese students (mean age = 12.74 years, SD = 0.57) from 4 middle schools completed anonymous questionnaires regarding inter‐parental conflict, impulsivity, school connectedness, and delinquency. Path analysis revealed school connectedness was a mediator in the relationship between inter‐parental conflict and adolescent delinquency. Furthermore, impulsivity moderated the indirect effect of school connectedness in the relationship between inter‐parental conflict and adolescent delinquency. A simple slope plot, together with a proportion affected (PA) index, indicated that impulsivity functioned more as a plasticity, rather than a vulnerability, factor in school connectedness. When school connectedness was low, high impulsivity was associated with more delinquent behaviors; however, when it was high, high impulsivity was associated with fewer delinquent behaviors.
