Finally, we examined a series of models that included both peer victimization and stressful life events to determine whether the observed associations were maintained with both types of stress exposure in the same model. A nearly identical pattern of results was obtained from these models. In the first step of the mediation analysis, both peer victimization, β=0.09, p=0.048, and stressful life events, β=0.09, p=0.042, were associated with aggressive behavior at Time 3, adjusting for baseline levels. In step 2 of the analysis, both peer victimization, β=.10, p=0.012, and stressful life events, β=0.08, p=0.028, were associated with Time 2 emotion dysregulation, controlling for Time 1 emotion dysregulation. In the final mediation model, neither peer victimization, β=−0.03, p=.514, nor stressful life events, β=0.03, p=.488, are associated with Time 3 aggressive behavior, adjusting for Time 1 levels, after controlling for emotion dysregulation.
