We examined whether the role of emotion dysregulation as a mediator of the relationship between peer victimization, stressful life events, and subsequent aggression was modified by gender. When the mediation paths of interest (See Fig. 1) were constrained to equivalence across males and females, the model fit did not significantly worsen for peer victimization, χ2(3)=7.04, p=0.071 or stressful life events, χ2(3)=5.32, p=.150, indicating that the process and strength of mediation was consistent across gender.
