About 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.

When to speak to someone. Reading about a topic cannot tell you whether it applies to you. Speak to a doctor or pharmacist if symptoms are severe, sudden, getting worse, or simply not going away — and seek emergency care immediately for chest pain, breathing difficulty, sudden weakness or confusion, or a serious allergic reaction.

Research on Teen Violence

160 studies areregistered for this condition on ClinicalTrials.gov, the U.S. National Library of Medicine's public registry. A selection is below — the links go straight to the registry entry, not to a summary of ours.

What a registered study does and does not mean. Registration means a study exists and has been declared publicly. It says nothing about whether the treatment being tested works, is safe, or is available to you. Many studies find no benefit — that is what research is for. Never seek out an experimental treatment on the strength of a registry entry alone.
