Knowra Conduct disorder Conduct disorder Conduct disorder is a childhood-onset psychiatric disorder involving a persistent pattern of behavior that violates others’ rights or major age-appropriate rules. Its symptoms include aggression, property destruction, deceit or theft, and serious rule violations.
Aggression : Behavior intended to cause physical or psychological harm to another person. Repeated aggression toward people or animals is one symptom group in conduct disorder.
Gene–environment interaction : The process by which genetic differences alter responses to environmental exposures, or vice versa. Inherited tendencies and adverse environments can combine in pathways associated with conduct problems.
Multisystemic therapy : An intensive family- and community-based treatment for serious behavioral problems in adolescents. It targets interacting influences at home, school, and among peers.
Antisocial personality disorder : A personality disorder involving a pervasive pattern of disregard for and violation of others’ rights in adulthood. It is an adult diagnosis; childhood conduct-disorder history is relevant but does not make the diagnoses interchangeable.
Antisocial behavior : Behavior that disregards or violates other people’s rights and social norms. Conduct disorder is a childhood diagnosis within the broader pattern of antisocial behavior.
Executive functions : Cognitive processes that support planning, inhibition, working memory, and goal-directed behavior. Difficulties with inhibition and planning can contribute to impulsive rule-breaking in some cases.
Parent management training : A behavioral intervention that teaches caregivers strategies for reinforcing prosocial behavior and setting consistent limits. It changes parent-child interaction patterns that may maintain conduct problems.
Intermittent explosive disorder : A disorder involving recurrent, disproportionate outbursts of impulsive aggression. Its defining problem is explosive aggression, not the broader persistent pattern of conduct-disorder symptoms.
Oppositional defiant disorder : A childhood disorder marked by persistent angry, argumentative, or defiant behavior toward authority figures. It involves defiance and conflict but not the serious rights violations that define conduct disorder.
Social learning theory : A theory that behavior is learned through observation, imitation, and consequences. It helps explain how coercive interactions and modeled aggression can reinforce conduct problems.
