Increased use of drugs or alcohol. Increased risk-taking behavior. Detailed plans to commit acts of violence. Enjoying hurting animals. Carrying a weapon.
Violence is a learned behavior and like any learned behavior, it can be changed.
However, in addition to recognizing these warning signs of violence, it's important to get help before a violent act occurs. Don't put off getting help when you see the last nine warning signs. Contact a mental-health professional who has experience working with young people who have problems with anger and violence. You can find a mental-health professional by asking your pediatrician or your child's school counselor for a recommendation. Contact the Youth Assistance office in your area.
