Conduct disorder is a behavioral and emotional disorder characterized by a persistent pattern of behaviors that violate the rights of others, important social rules, or age-appropriate expectations.
While children and teenagers sometimes test boundaries or break rules, conduct disorder involves behaviors that are more persistent, severe, and disruptive than ordinary childhood or adolescent misbehavior. Recognizing the signs early can help families understand when a professional psychiatric evaluation may be appropriate.
What Is Conduct Disorder?
Conduct disorder is a mental health condition involving a repeated and persistent pattern of aggressive behavior, serious rule violations, destruction of property, deceitfulness, or disregard for the rights of others.
It most often affects children and adolescents and can interfere significantly with family relationships, school performance, friendships, and everyday functioning.
Having occasional behavioral problems does not mean a child has conduct disorder. Diagnosis requires a careful evaluation of the type, frequency, duration, severity, and context of the behaviors.
What Are the Symptoms of Conduct Disorder?
Conduct disorder symptoms generally involve patterns of aggression, destruction of property, deceitfulness or theft, and serious violations of rules.
Symptoms vary from one child or teenager to another. Some young people primarily display aggressive behavior, while others may be more likely to break rules, lie, steal, skip school, or engage in risky behavior.
Common signs can include:
- Bullying, threatening, or intimidating others
- Frequently starting physical fights
- Aggressive behavior toward people or animals
- Deliberately destroying property
- Deliberately setting fires
- Repeated lying or manipulation
- Stealing
- Running away from home
- Frequently skipping school
- Repeatedly breaking important household or community rules
The presence of one behavior by itself does not establish a diagnosis.
What Are the Four Main Categories of Conduct Disorder Symptoms?
Symptoms associated with conduct disorder are commonly grouped into four broad categories: aggression toward people or animals, destruction of property, deceitfulness or theft, and serious violations of rules.
Understanding these categories can help parents recognize that conduct disorder is more than ordinary defiance or occasional misbehavior.
Aggression Toward People or Animals
Aggressive behaviors may include bullying, threatening others, initiating physical fights, deliberately hurting people or animals, or other behaviors that put others at risk.
Destruction of Property
Some children or teenagers may deliberately damage another person’s property or engage in fire-setting with the intention of causing damage.
Deceitfulness or Theft
Repeated lying, manipulating others for personal gain, stealing, or breaking into property may also occur.
Serious Rule Violations
Examples may include repeatedly running away from home, staying out despite significant parental restrictions, or frequently skipping school.
Conduct Disorder vs. Normal Childhood Misbehavior
The key difference between conduct disorder and ordinary misbehavior is the persistence, severity, and impact of the behavior.
Children and teenagers sometimes argue, become angry, test limits, or break rules. These behaviors alone do not necessarily indicate a psychiatric disorder.
Parents should become more concerned when problematic behaviors:
- Occur repeatedly over time
- Are unusually severe for the child’s age
- Occur in several settings
- Harm other people or animals
- Significantly affect school or relationships
- Involve serious violations of rules or laws
A qualified mental health professional can help distinguish developmentally typical behavior from a behavioral disorder.
Conduct Disorder vs. Oppositional Defiant Disorder
Conduct disorder and oppositional defiant disorder (ODD) are different behavioral disorders, although some symptoms can overlap.
Children with ODD typically show persistent patterns of anger, irritability, arguing, defiance, and conflict with authority figures.
Conduct disorder generally involves more serious behaviors that violate other people’s rights or major social rules, such as aggression, destruction of property, theft, or severe rule violations.
Some children with oppositional defiant disorder may later develop conduct disorder, but this does not happen to every child with ODD.
What Causes Conduct Disorder?
There is usually no single cause of conduct disorder. Instead, a combination of biological, psychological, developmental, family, and environmental factors may contribute.
Risk factors can include exposure to violence or trauma, abuse or neglect, family instability, learning difficulties, genetic vulnerability, and other mental health conditions.
Having one or more risk factors does not mean that a child will develop conduct disorder.
Can Conduct Disorder Occur With ADHD or Other Mental Health Conditions?
Yes. Children and teenagers with conduct disorder may also experience other psychiatric or developmental conditions.
These may include:
- ADHD
- Anxiety disorders
- Depression
- PTSD and trauma-related disorders
- Learning difficulties
- Substance use problems
- Other behavioral disorders
Identifying coexisting conditions is important because they can affect both behavior and the treatment plan.

How Is Conduct Disorder Diagnosed?
Conduct disorder should be diagnosed through a comprehensive evaluation rather than from a behavioral checklist alone.
A child and adolescent psychiatrist or other qualified mental health professional may evaluate the child’s behavior, emotional health, developmental history, family circumstances, school performance, relationships, and previous medical or psychiatric history.
Information from parents, caregivers, teachers, and other professionals may also help provide a more complete picture.
The evaluation should also determine whether another condition, such as ADHD, depression, anxiety, trauma, a learning disorder, or another behavioral disorder, could be contributing to the symptoms.
How Is Conduct Disorder Treated?
Treatment for conduct disorder is individualized and often involves the child, parents or caregivers, family, and sometimes the school.
Depending on the child’s needs, treatment may include:
- Behavioral therapy
- Parent management training
- Family therapy
- Cognitive behavioral approaches
- Social skills interventions
- School-based support
- Treatment of coexisting psychiatric conditions
There is no single treatment that is appropriate for every child.
Medication is not generally used simply to “stop bad behavior,” but it may sometimes be considered when a child also has conditions or symptoms such as ADHD, depression, severe impulsivity, or other psychiatric concerns.
Why Is Early Treatment Important?
Early evaluation and intervention can be especially valuable for children and adolescents who show persistent behavioral difficulties.
Without appropriate support, serious behavioral problems can affect academic progress, friendships, family relationships, safety, and later functioning.
Treatment can help children and families develop healthier ways of managing behavior, anger, emotions, conflict, and communication.
When Should Parents Seek Help?
Parents should consider professional evaluation when behavioral problems become persistent, severe, dangerous, or significantly interfere with life at home, school, or in relationships.
Professional help may be especially important when a child repeatedly:
- Hurts or threatens other people
- Is cruel to animals
- Destroys property
- Steals
- Runs away
- Frequently skips school
- Engages in increasingly risky or dangerous behavior
- Has significant emotional or behavioral changes
Parents do not need to determine whether their child has conduct disorder before scheduling an evaluation.

Frequently Asked Questions About Conduct Disorder
What is conduct disorder?
Conduct disorder is a behavioral and emotional disorder involving persistent patterns of aggression, serious rule violations, destruction of property, deceitfulness, theft, or behavior that violates the rights of other people.
What are the main signs of conduct disorder?
Common signs may include bullying, physical aggression, cruelty to people or animals, deliberate property destruction, repeated lying or stealing, running away, skipping school, and serious rule violations.
At what age does conduct disorder usually begin?
Conduct disorder can develop during childhood or adolescence. The age when symptoms first appear can be clinically important and is considered during a comprehensive psychiatric evaluation.
Is conduct disorder the same as bad behavior?
No. Occasional rule-breaking, arguments, anger, or misbehavior are common during childhood and adolescence. Conduct disorder involves a persistent and more serious pattern of behavior that significantly violates rules or the rights of others.
What is the difference between conduct disorder and ODD?
Oppositional defiant disorder generally involves persistent anger, irritability, arguing, and defiance toward authority figures. Conduct disorder typically involves more serious behaviors, including aggression, property destruction, theft, deceitfulness, or major violations of rules.
Can a child have both ADHD and conduct disorder?
Yes. ADHD and conduct disorder can occur together. Because ADHD, trauma, mood disorders, learning difficulties, and other conditions can influence behavior, a comprehensive evaluation is important.
Can conduct disorder be treated?
Yes. Treatment is individualized and may include behavioral interventions, parent training, family therapy, cognitive behavioral approaches, school support, and treatment of coexisting mental health conditions.
Does conduct disorder require medication?
There is no medication specifically used simply to treat all conduct disorder behaviors. Medication may sometimes be used when another condition or specific symptoms, such as ADHD, depression, or severe impulsivity, are also present.
Who diagnoses conduct disorder?
Conduct disorder can be diagnosed by appropriately trained mental health professionals. For children and adolescents with complex behavioral symptoms, evaluation by a child and adolescent psychiatrist can help identify conduct disorder and possible coexisting psychiatric conditions.
When should I take my child to a psychiatrist for behavioral problems?
Consider an evaluation when behavioral problems persist over time, become unusually severe, involve aggression or dangerous behavior, or significantly interfere with school, family relationships, friendships, or everyday functioning.
