Oppositional Defiant

Oppositional defiant disorder (ODD) is a persistent behavioral pattern of angry or irritable mood; argumentative, defiant behavior towards authority figures; and vindictiveness. In some children with ODD, these behaviors are only in evidence in one setting—usually at home. In more severe cases they occur in multiple settings. For a diagnosis of ODD, the frequency and intensity of these behaviors must be outside the typical range for a child’s developmental level, gender and culture.
