Conduct Disorder

Differences Between Boys and Girls

Boys are more likely to be diagnosed with Conduct Disorder than girls. Boys are also more likely to show aggressive behavior, threats, vandalism, and confrontational behavior than girls. Girls with Conduct Disorder are more likely to lie, skip school, run away, and shoplift, and are less confrontational in their behavior.

How Old Are They?

The diagnosis of Conduct Disorder typically occurs when children are in their late grade school to early high school years. However, children as young as 5-6 years old can be diagnosed with the condition. A majority of children stop showing Conduct Disorder behaviors by the time they reach adulthood; however, some individuals continue to have similar problems through adulthood.

While this report gives specific information for identifying signs of Conduct Disorder in children, parents and individuals should not try to diagnose any type of behavioral or emotional disorder in their children or themselves. A diagnosis of Conduct Disorder can only be made with confidence by a mental health professional who has been specifically trained in the assessment and treatment of this disorder.
