Although oppositional defiant disorder is sometimes viewed as a mild version of conduct disorder Conduct Disorder Conduct disorder is a recurrent or persistent pattern of behavior that violates the rights of others or violates major age-appropriate societal norms or rules.

The hallmark of this disorder is an interpersonal style characterized by irritability and defiance. However, children with a conduct disorder seemingly lack a conscience and repeatedly violate the rights of others (eg, bullying, threatening or causing harm, being cruel to animals), sometimes without any evidence of irritability.
Etiology of oppositional defiant disorder is unknown, but it is probably most common among children from families in which the adults engage in loud, argumentative, interpersonal conflicts. This diagnosis should not be viewed as a circumscribed disorder but rather as an indication of underlying problems that may require further investigation and treatment.

Treatment of Oppositional Defiant Disorder
Behavior modification therapy
Sometimes medications
Underlying problems (eg, family dysfunction) and coexisting disorders (eg, ADHD) should be identified and corrected. However, even without corrective measures or treatment, most children with oppositional defiant disorder gradually improve over time.
Initially, the treatment of choice for oppositional defiant disorder is a rewards-based behavior-modification program designed to make the child’s behaviors more socially appropriate. Many children can benefit from group-based therapy that builds social skills.
Sometimes medications used to treat depressive or anxiety disorders (see table Medications for Long-Term Treatment of Depression, Anxiety, and Related Disorders Drugs for Long-Term Treatment of Anxiety and Related Disorders* 
) may be beneficial.
Key Points
In oppositional defiant disorder, children typically lose their temper frequently, defy adults, disregard rules, and deliberately annoy other people.
Initially, use a rewards-based behavior modification program to make the child’s behaviors more socially appropriate; sometimes medications used to treat depressive and anxiety disorders can help.
