What percentage of children with Conduct Disorder are at risk for developing antisocial personality disorder?

• A. 20%
• B. 80%
• C. 60%
• D. 40%

Answer: (D)

Conduct Disorder in childhood often progresses to Antisocial Personality Disorder in adulthood, but progression is not inevitable. Longitudinal studies indicate that about two-fifths of youths with Conduct Disorder develop Antisocial Personality Disorder later on, roughly 40%. The rest have a range of outcomes: some desist or improve with age, while others continue with conduct problems without meeting APD criteria. The risk is higher with earlier onset, more persistent and severe conduct problems, and additional factors such as ADHD, family dysfunction, or early trauma; supportive interventions can reduce this risk. That's why the percentage closest to the typical trajectory is 40%.
