oppositional defiant disorder
A childhood behavioral disorder characterized by persistent defiant, hostile, and disobedient behavior toward authority figures.
Full Definition
Oppositional defiant disorder (ODD) is a psychiatric condition diagnosed in children and adolescents who exhibit a pattern of angry, vindictive, argumentative, and defiant behavior toward parents, teachers, and other authority figures. The behavior must persist for at least six months and significantly impair social, educational, or occupational functioning. ODD is distinguished from normal developmental defiance by its severity, frequency, and impact on daily functioning. It often co-occurs with ADHD and may precede the development of conduct disorder if left untreated.
