Conduct Disorder

Conduct disorder is a psychiatric category marked by a pattern of repetitive behavior wherein the rights of others or social norms are violated.
Symptoms include verbal and physical aggression, cruel behavior toward people and pets, destructive behavior, lying, truancy, vandalism, and stealing.[1]
Conduct disorder is a major public health problem because youth with conduct disorder not only inflict serious physical and psychological harm on others, but they are at greatly increased risk for incarceration, injury, depression, substance abuse, and death by homicide and suicide. After the age of 18, a conduct disorder may develop into antisocial personality disorder, which is related to psychopathy.[2]
The diagnostic criteria for Conduct Disorder (codes 312.xx, with xx representing digits which vary depending upon the severity, onset, etc. of the disorder) as listed in the DSM-IV-TR are as follows:
A repetitive and persistent pattern of behavior in which the basic rights of others or major age-appropriate societal norms or rules are violated, as manifested by the presence of three (or more) of the following criteria in the past 12 months, with at least one criterion present in the past 6 months:
Aggression to people and animals

Deceitfulness or theft
