High-risk benefited terms decreases beliefs attitudes supporting aggression, increases self-efficacy, behavior. Effects low-risk opposite direction. differential pattern for low- high-risk may account absence main many previous evaluations interventions middle school youth. These findings have important research policy implications efforts develop effective programs.
