Oppositional Defiant Disorder


Oppositional defiant disorder (ODD) is a childhood mental disorder characterized by a pattern of angry, antagonistic, hostile, negative, irritable, and/or vindictive behavior lasting at least six months and occurring more frequently than is typically observed for the child's age and developmental stage. Children diagnosed with ODD do not meet the clinical diagnostic criteria for conduct disorder .


Oppositional defiant disorder (ODD), a relatively new clinical classification, involves an ongoing pattern of antagonistic, defiant, and hostile behavior toward parents and other authority figures. Children and adolescents with ODD often have frequent temper tantrums , blame others for their misbehavior, argue excessively with adults, actively refuse to comply with adult rules and requests, deliberately defy adults and attempt to annoy or upset them, and are easily annoyed by others.


Before puberty , ODD is more common in boys than girls; however, after puberty ODD occurrence rates are about equal in boys and girls. The disorder typically begins by the age of eight. According to the American Academy of Child and Adolescent Psychiatry, approximately 5 to 15 percent of all school-aged children have ODD.

Causes and symptoms

Although the specific causes of ODD are unknown, genetics and environment are thought to play a role in its development. As of 2004 several theories about the causes of oppositional defiant disorder are being investigated. ODD may be related to the following:

ODD appears to be more common in families in which at least one parent has a history of a mood disorder, conduct disorder, attention deficit hyperactivity disorder (ADHD), antisocial personality disorder , or a substance abuse-related disorder. Children with one parent who is alcoholic or who has been in trouble with the law are almost three times more likely to have ODD. Additionally, some studies suggest that mothers with a depressive disorder are more likely to have children that develop ODD. ODD can also occur in conjunction with other conditions such as ADHD, learning disabilities, anxiety disorders, and mood disorders . About 50 percent to 65 percent of children with ADHD also have ODD.

Symptoms of ODD include a pattern of negative, hostile, and defiant behavior lasting at least six months. During this time four or more of the following must be present for a child to be diagnosed with ODD:

Additional problems may be present, including the following:

Parents of children and adolescents who exhibit symptoms of ODD should see a physician as soon as possible. Usually, a referral to a psychologist, psychiatrist, or therapist will be given.


ODD is diagnosed by psychological and psychiatric evaluations; interviews with family members, teachers, and caregivers; and observation and interviews with the child or adolescent. Diagnosis is based on clinical criteria defined in the American Psychiatric Association's Diagnostic and Statistical Manual of Mental Disorders , fourth edition, text revision C (DSM-IV-TR).

ODD often has characteristics in common with other psychological disorders and often occurs in conjunction with other conditions, such as ADHD or mood disorders. Therefore, diagnosis of ODD usually depends on exclusion of other disorders. A diagnosis of ODD is not made if the symptoms occur exclusively in psychotic or mood disorders, or if the child meets clinical criteria for conduct disorder, or, if the adolescent is 18 years old or older and meets clinical criteria for antisocial personality disorder. Children and adolescents with ODD do not exhibit the more serious aggressive behaviors or physical cruelty that is common in other disorders.


Treatment of ODD usually involves medication, and group, individual, and/or family therapy . Of these, individual therapy is the most common. The goal of therapy is to help provide a consistent daily schedule, support, rules, discipline , and limits, as well as to help train patients to get along with others by modifying behaviors. Therapy can occur in residential or day treatment facilities, in a medical setting, or on an outpatient basis. Therapy can instruct patients on how to effectively deal with ODD and help them learn how to do the following:

Therapy can also involve the parents. Parent management training focuses on teaching parents specific and more effective techniques for handling the child's opposition and defiance. Research has shown that parent management training is more effective than family therapy.

Stimulant medication is used only when ODD cooccurs with ADHD. Occasionally, children and adolescents with ODD may also have depression or anxiety disorders, and treatment with antidepressants and anti-anxiety medications can help alleviate some symptoms of ODD.


The prognosis for ODD varies. In some children, ODD evolves into a conduct disorder or a mood disorder. ODD, if left untreated, has approximately an 80 percent chance of turning into conduct disorder as a child ages. Later in life, ODD can develop into passive-aggressive personality disorder or antisocial personality disorder. ODD can cause significant social, academic, and/or occupational impairment. Generally, with treatment and long-term participation in therapy, adjustment in social settings and in the workplace can be made in adulthood.


As of 2004, ODD could not be prevented.
