What is Oppositional Defiant Disorder?

Oppositional defiant disorder is recognized by the American Psychological Association as a mental health disorder affecting children between the ages of six and nine years old. Oppositional defiant disorder is marked by argumentative, disobedient and hostile behavior toward authority figures as well as by a general negative attitude. The severity of the defiance can range from mild to uncontrollable.

The behavior associated with oppositional defiant disorder is very normal and common in four and five year old children. This age group typically exhibits intentionally annoying behavior, temper tantrums, arguing and ignoring requests made by adults. Although this behavior is difficult, it usually passes by age six, which is why oppositional defiant disorder is not clinically diagnosed at an earlier age. However, older children who are diagnosed with oppositional defiant disorder almost always exhibited difficult behavior in infancy and early childhood. Before age six, children with oppositional defiant disorder are typically irritable, have a difficult temperament in infancy and are argumentative in preschool.

True oppositional defiant disorder, that which is clinically diagnosed, affects approximately 1-4% of children, most often boys. It is closely linked with another behavioral problem known as conduct disorder. Conduct disorder is characterized by aggressive and hostile behavior in children over nine years of age through adolescence, including violence, vandalism and theft.

Not every child with oppositional disorder develops conduct disorder, but interestingly, research shows that all children diagnosed as having conduct disorder also had oppositional defiant disorder when they were younger. Mental health professionals believe that approximately 25% of children who have oppositional defiant disorder will also develop conduct disorder. Some, but definitively not all, people who have had oppositional defiant disorder and/or conduct disorder are at greater risk for antisocial or psychopathic personalities as adults.

It is not conclusive as to why some children develop oppositional defiant disorder. Mental health professionals believe that a low socioeconomic status, antisocial parents or the loss of an important caregiver may be causal factors in both oppositional defiant disorder and conduct disorder. However, oppositional defiant disorder is often found in extremely intelligent or gifted children that are labeled oppositional because they tend to think outside of societal norms and consequently to question authority. Gifted children usually grow out of their oppositional defiant disorder as they mature.
