Oppositional defiant disorder (ODD) is a behavior disorder, usually diagnosed in childhood, that is characterized by uncooperative, defiant, negativistic and irritable behaviors toward parents, peers, teachers and other authority figures. Children and adolescents with ODD are more distressing or troubling to others than they are distressed or troubled themselves.
Whose Is Affected?
Behavior disorders, as a category, are, by far, the most common reason for referrals to mental health services for children and adolescents. Oppositional defiant disorder is reported to affect between 2-16% of children and adolescents in the general population. ODD is more common in boys than in girls.
