Conduct disorder is a persistent pattern of aggression, property destruction, deceit or theft, and serious rule violations in a child or adolescent. It is treated with family-based therapies such as multisystemic therapy and parent management training, CBT for the young person, and medication for co-occurring ADHD, mood disorders or severe aggression. Early treatment substantially improves long-term outcomes.
That fear is understandable, but the outlook is better than the reputation. Most children with conduct disorder do not go on to adult antisocial behavior, particularly when it begins in adolescence and when it is treated. The treatments that work are intensive, family-based and practical, and they are more effective when ADHD, depression, trauma and substance use are identified and treated alongside. Stedfast Psychiatry's child and adolescent providers evaluate the full picture and deliver or coordinate treatment that engages the family, the school and when necessary the courts.
Symptoms of conduct disorder
- Bullying, threatening or intimidating others, or initiating physical fights
- Physical cruelty to people or animals, or use of a weapon that can cause serious harm
- Deliberately setting fires or destroying others' property
- Breaking into houses, buildings or cars, or stealing with or without confrontation
- Frequent lying to obtain things or avoid obligations
- Staying out at night against parental rules before age 13, running away from home overnight, or frequent truancy
- Lack of remorse, empathy or concern about performance in some cases (the limited prosocial emotions specifier)
- Co-occurring impulsivity, irritability, low mood, substance use or academic failure
Causes and risk factors
Conduct disorder results from a combination of genetic vulnerability, neurodevelopmental factors and environment. Heritability is substantial, and traits such as impulsivity, low fear response, reduced sensitivity to punishment and difficulty reading others' emotions are partly inherited. ADHD is present in a large share of cases and increases the risk of early-onset, persistent conduct problems. Prenatal exposure to alcohol, tobacco or drugs, low birth weight, early brain injury and language impairment all contribute. Brain imaging studies show differences in the amygdala and prefrontal regions involved in empathy, threat processing and self-control.
Environment shapes whether vulnerability becomes disorder. Exposure to violence, physical or sexual abuse, neglect, harsh or inconsistent discipline, parental substance use or criminality, family instability, poverty and association with deviant peers all raise risk, and they often cluster. Trauma deserves specific mention: many adolescents with conduct disorder have significant trauma histories, and aggression is sometimes the visible face of PTSD. Childhood-onset conduct disorder (before age 10) is more strongly neurodevelopmental and has a worse course; adolescent-onset conduct disorder is more peer-driven and more likely to resolve by adulthood.
The one-year prevalence of conduct disorder is estimated at 2 to 10 percent of children and adolescents, with a median of about 4 percent, and it is more common in boys.

How we diagnose it at Stedfast Psychiatry
Evaluation involves the young person, the parents or guardians and, with consent, information from school, pediatrician and any involved agencies. It usually takes 90 minutes, often across two visits. We take a detailed history of the behaviors, their onset, frequency and context, a developmental and trauma history, substance use history and family history. We use structured rating scales, including the Vanderbilt scales, the Child Behavior Checklist and Youth Self-Report, the Inventory of Callous-Unemotional Traits when relevant, and screening for depression (PHQ-A), anxiety and trauma (CATS or UCLA PTSD index). Substance use is assessed with the CRAFFT.
We screen specifically for the conditions that commonly coexist and change treatment: ADHD, depression, bipolar disorder, PTSD, substance use disorders, learning disorders, language impairment and intellectual disability. We distinguish conduct disorder from ODD, intermittent explosive disorder, adjustment disorder with disturbance of conduct, and behavior that is a response to abuse or an unsafe environment. When learning or language problems are suspected we recommend psychoeducational testing, and when the picture suggests a medical contributor, such as a seizure disorder or head injury, we refer appropriately. The DSM-5 subtypes (childhood-onset, adolescent-onset) and the limited prosocial emotions specifier are recorded because they guide prognosis and approach.
Treatment options
Medication management
No medication is FDA-approved for conduct disorder, and medication is used to treat co-occurring conditions and, selectively, severe aggression. Stimulants for co-occurring ADHD reduce aggression and rule breaking substantially and are the best-supported medication intervention; guanfacine extended-release and clonidine extended-release are alternatives that also help impulsive aggression. When depression, anxiety or PTSD is present, an SSRI such as fluoxetine or sertraline is appropriate. For severe, persistent aggression that has not responded to behavioral treatment and treatment of comorbid conditions, risperidone has the most evidence (it is FDA-approved for irritability in autism, not for conduct disorder) and aripiprazole is an alternative; both require monitoring of weight, glucose, lipids, prolactin and movement side effects, and we use them at the lowest dose for the shortest time. Mood stabilizers such as lithium or valproate have some evidence for aggression in hospitalized adolescents. We avoid benzodiazepines, which can disinhibit, and we treat substance use disorders directly.
Psychotherapy
Family-based treatments are the core. For children under 12, parent management training and Parent-Child Interaction Therapy have strong evidence. For adolescents, multisystemic therapy (MST), functional family therapy (FFT) and multidimensional treatment foster care have the best outcomes, reducing offending, out-of-home placement and substance use; these are intensive, home- and community-based programs, and we refer to and coordinate with the agencies that provide them in Florida and South Carolina. Individual cognitive behavioral therapy teaches problem solving, anger management, perspective taking and moral reasoning; the Problem-Solving Skills Training and Aggression Replacement Training models are well studied. Trauma-focused CBT is used when PTSD is present. We work with schools on behavior plans, alternative placements and educational supports, and with juvenile justice when the young person is involved with the courts, because treatment is more effective than detention and the research is clear on that point.
What to expect
The first visit is a comprehensive evaluation with the young person and family, with rating scales and school information gathered beforehand when possible. You will leave with a diagnosis, an honest assessment of the drivers, and a plan that typically combines family-based therapy, individual CBT and medication for any co-occurring condition. We refer to intensive community programs when the severity warrants it and coordinate with them. Follow-ups are every two to four weeks initially. Many follow-ups and some therapy can be done by video anywhere in Florida or South Carolina, although initial evaluations and higher-risk situations are often better in person at one of our offices.
When to seek help
Seek an evaluation as soon as a pattern of aggression, cruelty, fire setting, stealing, running away or truancy becomes apparent; earlier treatment produces better outcomes. If your child has threatened or injured someone, has access to weapons, or has expressed thoughts of harming himself or herself, call or text 988, the Suicide and Crisis Lifeline, go to the nearest emergency room, or call 911 if there is immediate danger. Adolescents with conduct disorder have an elevated risk of suicide, and the combination of impulsivity, substance use and depression is particularly dangerous.
Childhood-onset and adolescent-onset conduct disorder
The DSM-5 distinguishes conduct disorder by whether at least one symptom was present before age 10. Childhood-onset conduct disorder is more common in boys, more strongly linked to ADHD, language problems and neurodevelopmental vulnerability, and more likely to persist into adult antisocial behavior. Adolescent-onset conduct disorder is more evenly distributed between boys and girls, usually emerges in the context of peer influence, and tends to remit as the young person matures and leaves the peer group. The distinction guides prognosis and the intensity of treatment, with childhood-onset cases warranting the most comprehensive and sustained intervention.
The limited prosocial emotions specifier
Some children with conduct disorder show a pattern of callous-unemotional traits: lack of remorse, lack of empathy, indifference to performance and shallow or deficient affect. The DSM-5 records this as the limited prosocial emotions specifier when it has been present for at least a year across settings. These children have a more severe and stable course, show reduced response to punishment and reduced fear, and have distinct patterns on brain imaging. They are not untreatable. They respond to reward-based parenting, consistent structure, treatment of ADHD and interventions that build emotion recognition, and the specifier helps us tailor the approach rather than apply a punishment-heavy model that does not work for them.
Comorbid conditions
Conduct disorder rarely stands alone. ADHD is present in a third to half of cases, depression and anxiety in a quarter to a third, substance use disorders in a large share of adolescents, and PTSD in many, particularly those with abuse histories. Learning disorders and language impairment are common and contribute to school failure and frustration. Each of these is treatable, and treating them reduces conduct symptoms. An adolescent whose aggression is driven by untreated PTSD and cannabis use needs a different plan from one whose aggression is driven by ADHD and peer influence, which is why the evaluation is thorough.
Differential diagnosis
Oppositional defiant disorder lacks aggression toward people and animals, property destruction, deceit and serious rule violation. Intermittent explosive disorder involves impulsive, unplanned outbursts without the broader pattern of rule breaking. Adjustment disorder with disturbance of conduct is a time-limited reaction to a stressor. Bipolar disorder involves episodic mood elevation. Behavior that is a rational response to an abusive or unsafe environment, such as running away from a violent home, is not conduct disorder. Substance intoxication and withdrawal can produce aggression. In some adolescents, conduct problems are the presenting face of autism spectrum disorder, intellectual disability or a language disorder that has gone unrecognized.
Working with schools and the justice system
School engagement is protective, and school exclusion worsens outcomes, so we advocate for behavior plans, educational supports and alternative placements over expulsion. When ADHD or a learning disorder is present, an individualized education program or 504 plan is appropriate. For adolescents involved with juvenile justice, we coordinate with probation and diversion programs, provide documentation when authorized, and support referral to evidence-based community programs. We are clear with families about the limits of confidentiality and about our clinical rather than forensic role.
Prognosis
With treatment, the majority of children and adolescents with conduct disorder improve, and most adolescent-onset cases resolve by early adulthood. The strongest predictors of a good outcome are early intervention, treatment of ADHD and other comorbid conditions, an engaged family, continued school attendance and separation from antisocial peers. The risks to prevent are substance use disorders, school dropout, early parenthood, injury and involvement with the criminal justice system. These are not inevitable, and effective, family-based treatment changes the trajectory for most young people.
Frequently asked questions
Does a conduct disorder diagnosis mean my child will become a criminal?
No. Most children with conduct disorder do not become antisocial adults, and the risk depends heavily on onset age, severity, comorbidity and treatment. Adolescent-onset conduct disorder, the more common form, usually resolves by the mid-twenties. Childhood-onset conduct disorder with untreated ADHD and callous-unemotional traits has a harder course, which is exactly why early and intensive treatment matters. The diagnosis is a description of current behavior, not a life sentence.
What is the difference between ODD and conduct disorder?
ODD involves angry mood, arguing, defiance and spite, but the child does not violate others' basic rights. Conduct disorder involves aggression toward people or animals, destroying property, lying or stealing, and serious rule violations like running away. ODD often precedes conduct disorder, but most children with ODD never develop it. The two conditions share risk factors and treatments, and both improve with parent-based therapy and treatment of ADHD.
What is multisystemic therapy?
MST is an intensive, home-based program for adolescents with serious conduct problems, including those involved with juvenile justice. A therapist works with the family several times a week for three to five months, is available around the clock, and addresses every system around the young person: family rules and supervision, school engagement, peer group, and neighborhood. It has reduced rearrests and out-of-home placements in multiple randomized trials. We refer to MST and functional family therapy providers in Florida and South Carolina and coordinate psychiatric care alongside.
Is medication necessary?
Only for what it can treat. ADHD, present in a third to half of children with conduct disorder, responds to stimulants, and treating it reduces aggression and rule breaking. Depression, anxiety and PTSD respond to SSRIs and therapy. Severe aggression that has not improved with these steps may justify a time-limited trial of risperidone or aripiprazole with careful monitoring. Medication never replaces family-based treatment, and we review the need for each prescription at every visit.
What are callous-unemotional traits?
A subgroup of children with conduct disorder show limited guilt, reduced empathy, lack of concern about performance and shallow emotion, recorded in the DSM-5 as the limited prosocial emotions specifier. These children have a more persistent course and respond less to punishment-based discipline, but they do respond to treatment that emphasizes warmth, reward and consistent structure, and to treatment of ADHD. Identifying the trait changes the approach rather than the goal.
My teenager is in trouble with the courts. Can you still help?
Yes, and this is often where treatment matters most. We evaluate and treat adolescents involved with juvenile justice, provide documentation for the court when requested and authorized, and coordinate with probation officers and diversion programs. Research consistently shows that treatment reduces reoffending more than detention does. Our role is clinical, not legal, and we are transparent with families about what information we share and with whom.
Is treatment for conduct disorder covered by insurance and available by telehealth?
Psychiatric evaluation, medication management and therapy are covered by most commercial plans and the Medicaid managed care plans we accept; a self-pay new-patient visit is $185. Intensive programs such as MST are typically funded through Medicaid, state agencies or the juvenile justice system. Follow-up visits and some therapy work well by video throughout Florida and South Carolina, though initial evaluations and higher-risk situations are usually better in person.
What can we do at home right now?
Increase supervision: know where your child is, with whom and when they will be home. Set a small number of clear, non-negotiable rules with consistent, proportionate consequences. Remove access to weapons, alcohol and medications. Stay engaged and warm even when enforcing limits, because the relationship is the lever for change. Reduce contact with peers who are involved in the same behavior where you can. Make sure your own stress and mental health are addressed; parenting a child with conduct disorder is exhausting and you need support too.
