The three violence sup types:
Self-Inflicted Violence: is best described as the intentional harm of one's own body without conscious suicidal intent. Most types involve cutting of one's own flesh (usually the arms, hands, or legs), burning one's self, interfering with the healing of wounds, excessive nail biting, pulling out one's own hair, hitting or bruising one's self, and intentionally breaking one's own bones.
Interpersonal Violence and Abuse refers to violence and abuse that occurs between people who know each other. It can occur within or outside a family setting. The first is when there is an unlawful exercise of physical force that may result in criminal charges or physical and/or sexual abuse.
Collective violence receives a high degree of public attention. Violent conflicts between nations and groups, state and group terrorism, rape as a weapon of war, the movement of large numbers of people displaced from their homes, and gang warfare – all these occur on a daily basis in many parts of the world.
