Uses a four-level social-ecological model (individual, relationship, community, and societal) to better understand violence and the effect of potential prevention strategies. It allows one to understand the range of factors that put people at risk for violence or protect them from experiencing or perpetrating violence. The overlapping rings in the model illustrate how factors at one level influence factors at another level.
