Violence prevention, as a field of research, policy and programming is broken into broad categories that help frame and guide prevention approaches. These categories include: interpersonal violence, self-directed violence or suicide, elder abuse, gender-based violence (often called “violence against women” in the U.S.), violence against children, youth violence, and collective violence (or war). These categories can be further subdivided into more specific forms such as gang violence, intimate-partner violence (domestic violence), child sexual abuse, etc. Although there is some overlap across forms, the risk factors — the pathways toward each form of violence — are different. And, as you might surmise, the approaches to prevention for each are likewise different.
