Disruptive, impulse-control, and conduct disorders (PEARLS)

Disruptive, impulse-control, and conduct disorders
Conduct disorder A pattern of repetitive behavior in which the rights of others or social norms are violated
Oppositional defiant disorder A pattern of negativistic, hostile, and defiant behavior, during which a child often loses her or his temper, often argues with adults, and often actively defies or refuses to comply with adults' requests or rules.
*Oppositional defiant disorder is a less intense form of conduct disorder. Children who continue with the chronic behavior are at risk of developing conduct disorder.
Conduct disorder
Patient will present as → a 14-year-old who is referred to your office for unusual animal cruelty and bullying at school. 

A child is referred to your office for unusual animal cruelty and bullying at school

  • A repetitive pattern violating the basic rights of others or major age-appropriate norms — four categories: aggression to people/animals · destruction of property · deceitfulness or theft · serious rule violations
  • Often the precursor to antisocial personality disorder (not diagnosable before age 18)
  • vs ODD: ODD children are defiant but not aggressive to people/animals, destructive, or deceitful

DX: DSM-5≥ 3 of 15 criteria in the past 12 months (from any of the four categories), with ≥ 1 in the past 6 months

  • Examples: bullying/fights/weapon use/cruelty · fire-setting/property destruction · breaking in/lying/stealing · staying out at night, running away, truancy before age 13
  • Specify childhood- vs adolescent-onset and "with limited prosocial emotions"; rule out substance use and abuse as drivers

TX: Multimodal psychosocial treatment integrating individual, school, and family settings

  • Parent management training has the best evidence; multisystemic therapy for severe cases
  • Treat comorbid ADHD, depression, and substance use — no medication treats conduct disorder itself
Oppositional defiant disorder
