Conduct Disorder (CD) is a serious mental health condition that affects children and teenagers. It is defined by a consistent pattern of behavior in which a young person violates the rights of others or breaks age-appropriate societal rules and norms. These behaviors often include aggression, deception, destruction of property, and serious rule violations.
Early identification and intervention are essential for managing symptoms and supporting both the child and their family.
What Is Conduct Disorder?
According to the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition, Text Revision (DSM-5-TR), Conduct Disorder is diagnosed when a young person demonstrates at least three out of 15 specific behaviors over the past 12 months, with at least one behavior occurring in the past 6 months. These behaviors fall into four key categories:
- Aggression Toward People and Animals
- Frequently bullies, threatens, or intimidates others
- Initiates physical fights
- Uses weapons that can cause serious harm (e.g., bat, brick, knife)
- Has been physically cruel to people or animals
- Commits theft involving confrontation (e.g., mugging, extortion)
- Forces others into sexual activity
- Destruction of Property
- Intentionally starts fires to cause damage
- Deliberately destroys others’ belongings
- Deceitfulness or Theft
- Breaks into homes, buildings, or vehicles
- Lies to gain benefits or avoid responsibilities (“cons” others)
- Steals valuable items without confronting the victim (e.g., shoplifting)
- Serious Violations of Rules
- Stays out late without parental permission before age 13
- Runs away from home overnight (at least twice, or once without returning for a long time)
- Frequently skips school before age 13
Types of Conduct Disorder
Childhood-Onset Type
Symptoms appear before age 10 and are often more severe. This type is more common in boys and may follow a history of oppositional defiant disorder (ODD). These children may also struggle with attention-deficit/hyperactivity disorder (ADHD) or other developmental conditions. They are more likely to display aggressive behaviors and face ongoing issues into adulthood.
Adolescent-Onset Type
Symptoms begin after age 10. These individuals may have more typical peer relationships and are less likely to show aggression. However, their conduct problems can still be serious and may occur in group settings.
Developmental Patterns and Risk Factors
Symptoms may start as early as preschool, but most begin between middle childhood and adolescence. Boys are more likely to display physical aggression, stealing, and vandalism, while girls may be more likely to lie, skip school, run away, or engage in risky behaviors like prostitution.
Conduct disorder can have serious consequences, including:
- Academic failure or expulsion
- Trouble maintaining employment
- Legal involvement
- Risk of sexually transmitted infections and unplanned pregnancy
- Physical injury from fights or risky behaviors
Why Early Intervention Matters
Conduct disorder can significantly disrupt a young person’s ability to function in school, at home, and in the community. Without support, these behaviors can persist into adulthood and lead to long-term challenges. However, with the right treatment—often involving a combination of therapy, family support, behavioral strategies, and, in some cases, medication—young people with conduct disorder can improve their emotional regulation, social skills, and overall functioning.
