ODD is a type of disruptive behavior disorder (DBD). Children with ODD are often hostile, defiant, angry, or uncooperative. This especially applies to authority figures, such as parents, caregivers, and teachers. And it’s common, affecting up to 16% of all school-age children and adolescents, according to the American Academy of Child & Adolescent Psychiatry. ODD is usually diagnosed during childhood and adolescence. The Centers for Disease Control and Prevention says that ODD starts before age 8 and no later than age 12. For some, it can take until adolescence to get a diagnosis of ODD.
