The document discusses conduct disorder in youth under age 10. It notes that conduct disorder is one of the most common reasons for child psychiatric referrals, with 70% of cases first occurring between ages 4-9. For these young children, non-pharmacological treatments are preferred over medication, including behavioral family interventions that modify the family environment. Parent management training and behavior modification are effective alternative treatments. Teachers also need training to help modify problematic classroom behaviors through reinforcement of positive behaviors. Untreated, conduct disorder can lead to problems like school suspension or involvement in the juvenile justice system.
