Conduct Disorder

The symptoms of conduct disorder often fall into four broad categories: aggressive behavior, destructive behavior, deceitful behavior, and violation of rules. Each category involves different symptoms. 

Aggressive behavior

Below are symptoms associated with aggression in children with conduct disorder: 

• Frequent physical fights or assaults
• Using a weapon in fights
• Bullying, intimidating, or threatening others
• Cruelty or violence toward animals
• Forceful sexual activity (assault) 

Destructive behavior

Destructive behavior in children with conduct disorder may involve actions like the following:

• Deliberately setting fires with the intention of causing damage
• Vandalism or deliberate destruction of property

Deceitful behavior

Deceitful behavior in children with conduct disorder involves the following symptoms:

• Lying or deceit for personal gain or pleasure
• Shoplifting or theft
• Breaking into someone's house, building, or car
• Attempting to manipulate others 

Violation of rules

Below are some ways children with conduct disorder may violate rules: 

• Staying out at night despite parental objections, beginning before age 13
• Running away from home overnight at least twice while living in a parental or parental surrogate home or once without returning for a lengthy period
• Truancy from school, beginning before age 13

Secondary symptoms 

Conduct disorder can also present with secondary symptoms associated with the consequences of the disruptive behavior, including:

• Problems in school or problems with the law
• Drug or alcohol use
• Risky sexual behavior
• Suicidal thoughts or behaviors

Effects of conduct disorder symptoms

These behaviors must cause significant impairment in the individual's social, academic, or occupational functioning for a provider to diagnose conduct disorder. In addition, experts will look at whether children and teens show few signs of concern or guilt about their harmful behavior, often blaming others.

Children with this condition may have difficulty regulating their emotions, appear irritable, or frequently lose their temper. The behaviors associated with conduct disorder can vary in severity and lead to serious consequences if left untreated.

The exact cause of conduct disorder is unknown, but it is believed to be a complex interplay of genetic, biological, psychological, and environmental factors.

Genetic and biological factors of conduct disorder

Below are some of the genetic and biological factors that could cause conduct disorder:  

• A family history of conduct disorder, antisocial personality disorder, or other personality or mood disorders can increase the risk of developing the condition.
• Abnormalities in the brain, especially in the frontal cortex, which is responsible for decision-making, impulse control, and judgment, may contribute to conduct disorder.
• Exposure to substances while in the womb may influence the development of conduct disorder.

Psychological factors of conduct disorder

Below are potential psychological causes of conduct disorder: 

• An individual's temperament, such as impulsivity or difficulty managing anger, can play a role in the development of the disorder.
• Learning disabilities or lower intelligence quotient (IQ) can contribute to the manifestation of conduct disorder.

Environmental factors of conduct disorder

Below are potential environmental factors that could cause conduct disorder: 

• A dysfunctional family environment, such as high family conflict or poor parenting practices, can be a risk factor for conduct disorder.
• Exposure to violence or trauma, such as child abuse or community violence, can increase the risk of conduct disorder.
• Socioeconomic hardship, including poverty, can also be a risk factor.

Causes of conduct disorder symptoms can vary widely and include stressors such as changes in family structure, school problems, or conflicts with peers. Note that these factors do not cause conduct disorder alone. Instead, they may increase the risk of a behavior disorder when combined with other factors. Early intervention can often prevent the escalation of symptoms and improve long-term outcomes.

The treatment for conduct disorder aims to reduce or eliminate symptom manifestations, improve social and academic functioning, and cultivate positive family interactions. A comprehensive treatment approach often involves psychotherapy, medication, and supportive services.

Medication to treat conduct disorder

There is no specific medication to treat conduct disorder and psychosocial interventions remain the first line of treatment. Still, various medications can be used to manage co-occurring conditions or specific troubling symptoms, including but not limited to the following: 

• Stimulant medications, like methylphenidate and amphetamine, can be effective for children with comorbid ADHD.
• Antidepressants or mood stabilizers may help children manage symptoms if they have a co-occurring mood disorder such as signs of depression.
• Atypical antipsychotics may be used in severe cases or when other treatment methods fail. They can help manage aggression but have significant side effects and must be used cautiously.

Consult a medical doctor before starting, changing, or stopping one of your child’s medications. 

Other treatment options for conduct disorder

Other interventions may be helpful, depending on the specific circumstances of the child or adolescent. School-based programs can support academic difficulties and include behavior management strategies.

Residential treatment programs may benefit adolescents with severe symptoms who have not responded to other forms of treatment. These programs provide structured and therapeutic environments for children to live and receive treatment. 

Self-care to manage conduct disorder

Self-care strategies can also contribute to managing conduct disorder symptoms, including:

• Regular physical activity can help children manage symptoms by reducing tension and promoting improved mood.
• A balanced diet and sufficient sleep can also improve overall mental health.
• Mindfulness and relaxation techniques can assist in anger management and impulse control.

The effectiveness of treatment can vary significantly from person to person. While conduct disorder can be a challenging condition to manage, with consistent treatment and support, individuals with conduct disorder can learn to manage their symptoms and lead productive lives.

Therapy can be a critical component of treatment for conduct disorder. Online platforms like BetterHelp for adults and TeenCounseling for teens aged 13 to 19 can make it easier to find quality mental healthcare. With an online platform, you can connect with licensed therapists specializing in treating conduct disorder and related conditions and receive support via phone, video, or live chat sessions. 

Conduct disorder resources

Additional resources include the following: 

• American Academy of Child & Adolescent Psychiatry (AACAP): AACAP provides resources for families of children with mental health conditions, including conduct disorder.
• Substance Abuse and Mental Health Services Administration (SAMHSA): SAMHSA offers a variety of resources, including a treatment services locator and a helpline for individuals and families facing mental health or substance use disorders.
• National Institute of Mental Health (NIMH): The NIMH provides comprehensive information on various mental health disorders, including conduct disorders.

Emerging research on conduct disorder continually improves our understanding of its causes and treatment options. One area of interest involves the role of the brain's anatomy and function in developing this condition.
A study highlighted in the National Center for Biotechnology Information's report found differences in the amygdala and prefrontal cortex, brain areas related to emotion processing and decision-making, of individuals with conduct disorder. This study suggests that biological factors may be more significant than previously believed.

Comprehensive treatments for conduct disorder

Regarding treatments, research is expanding beyond traditional methods to consider comprehensive and integrative approaches. According to Mental Health America's report, prevention and early intervention strategies that focus on improving family and school environments show promise in reducing antisocial behavior in children and adolescents (conduct disorder can be a precursor to antisocial traits and tendencies or antisocial personality disorder). 

Early intervention for conduct disorder

These strategies include family-based interventions, parenting programs, school-based programs, and community-wide interventions. These results underscore the importance of a holistic approach when treating conduct disorder, addressing the individual and their environment. Advancements in these research areas can be promising for looking at better diagnostic tools and more effective treatments for conduct disorder in the future.

Conduct disorder is two to four times higher in boys

Conduct disorder is primarily diagnosed in children and has been found to be two to four times more common in cisgender boys than cisgender girls. Further research is needed to understand the prevalence of conduct disorder across a broader spectrum of gender identities.¹

Below are more statistics on conduct disorder:

• According to the American Academy of Child & Adolescent Psychiatry, conduct disorder affects approximately 2% to 10% of children in the United States, making it one of the most common childhood disorders.
• Conduct disorder often co-occurs with other mental health conditions. Studies found that over 40% of children with conduct disorder also have ADHD.
• Treatment for conduct disorder can be effective. The American Psychiatric Association notes that many children and teens with conduct disorder show significant improvement with early intervention and comprehensive treatment plans. These plans may reduce the chances of a child developing ASPD later in life.
