Teen Violence

Teen violence refers to harmful behaviors that can start early and continue into young adulthood. The young person can be a victim, an offender, or a witness to the violence.

Violent acts can include:

  • Bullying
  • Fighting, including punching, kicking, slapping, or hitting
  • Use of weapons such as guns or knives

Some violent acts can cause more emotional harm than physical harm. Others can lead to serious injury or even death.

An important risk factor for violence in teens is the behavior of their friends and classmates. You should know who your kids hang out with and encourage healthy behavior and relationships.
