(HealthDay News) -- People who are prone to violence often have trouble controlling their behavior, the American Psychological Association says.
The group says there may be tell-tale signs that a young person is about to "act out," such as:
- Having a history of violent or aggressive behavior.
- Being young at the first violent incident.
- Having been a victim of bullying.
- Having a history of discipline problems or frequent conflicts with authority.
- Being a victim of early child abuse or neglect.
- Having seen violence at home.
- Having a history of cruelty to animals.
- Having a significant mental illness.
- Being callous or lacking concern for others.
- Having a history of vandalism.
