Risk Factors

This problem is more common in boys.

Other things that may raise the risk are:

  • Having other family members with antisocial behavior
  • Having a mother who used alcohol, smoked, or had a poor diet while pregnant
  • Being around violence
  • Prior child abuse
  • Having parents who have:
    • Mental health problems
    • Substance misuse issues
    • Relationship problems
    • Had legal problems
    • Poor parenting skills



A child with this problem may:

  • Lack care or empathy
  • Bully
  • Fight
  • Use weapons
  • Be cruel to people or animals
  • Steal or lie
  • Force sex acts on others
  • Harm things that belong to others on purpose
  • Break rules
  • Start fires


You will be asked about your child’s symptoms and health history. You will also be asked questions about your child's behaviors. A physical exam will be done. A mental health exam may also be done. This is often enough to make the diagnosis.



The goal is to stop problem behaviors. Choices are:

  • Parent training
  • Individual or group therapy to help children learn to control emotions
  • Medicines may be used with other treatments to manage certain symptoms, such as mood swings


Early care for emotional and behavioral problems may lower the risk of conduct disorder.
