Oppositional defiant disorder (ODD) is characterized by an ongoing pattern of uncooperative, defiant, and hostile behavior toward authority figures. While some oppositional behavior is normal for children aged 2-3 and early adolescents, ODD involves behavior that is too frequent, consistent, and severe compared to other children and negatively impacts social, family, and academic functioning. There is no single known cause of ODD but contributing factors may include genetics, temperament, family dynamics, lack of supervision or stability. Treatment involves parent training programs, cognitive behavioral therapy, social skills training, and in some cases medication. Prognosis is better with early treatment, though about half of children with untreated ODD may develop conduct disorder.
