"Conduct disorder" refers to a group of behavioral and emotional problems in youngsters. Children and adolescents with this disorder have great difficulty following rules and behaving in a socially acceptable way. They are often viewed by other children, adults and social agencies as "bad" or delinquent, rather than mentally ill. Many factors may contribute to a child developing conduct disorder, including brain damage, child abuse or neglect, genetic vulnerability, school failure, and traumatic life experiences.

Children or adolescents with conduct disorder may exhibit some of the following behaviors:

Aggression to people and animals

Destruction of Property

Deceitfulness, lying, or stealing

  • has broken into someone else's building, house, or car
  • lies to obtain goods, or favors or to avoid obligations
  • steals items without confronting a victim (e.g. shoplifting, but without breaking and entering)

Serious violations of rules

  • often stays out at night despite parental objections
  • runs away from home
  • often truant from school

Children who exhibit these behaviors should receive a comprehensive evaluation by an experience mental health professional. Many children with a conduct disorder may have coexisting conditions such as mood disorders, anxiety, PTSD, substance abuse, ADHD, learning problems, or thought disorders which can also be treated. Research shows that youngsters with conduct disorder are likely to have ongoing problems if they and their families do not receive early and comprehensive treatment. Without treatment, many youngsters with conduct disorder are unable to adapt to the demands of adulthood and continue to have problems with relationships and holding a job. They often break laws or behave in an antisocial manner.

Treatment of children with conduct disorder can be complex and challenging. Treatment can be provided in a variety of different settings depending on the severity of the behaviors. Adding to the challenge of treatment are the child's uncooperative attitude, fear and distrust of adults. In developing a comprehensive treatment plan, a child and adolescent psychiatrist may use information from the child, family, teachers, community (including the legal system) and other medical specialties to understand the causes of the disorder.

Behavior therapy and psychotherapy are usually necessary to help the child appropriately express and control anger. Special education may be needed for youngsters with learning disabilities. Parents often need expert assistance in devising and carrying out special management and educational programs in the home and at school. Home-based treatment programs such as Multisystemic Therapy are effective for helping both the child and family.Treatment may also include medication in some youngsters, such as those with difficulty paying attention, impulse problems, or those with depression.

Treatment is rarely brief since establishing new attitudes and behavior patterns takes time. However, early treatment offers a child a better chance for considerable improvement and hope for a more successful future.
