ODD is a persistent behavioural pattern of anger or irritability; argumentative, defiant behaviour toward authority figures; and vindictiveness lasting at least 6 months. In some children with ODD, these behaviours are only evident 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 behaviours must be outside the typical range for the child’s gender, culture and developmental level.
Children or adolescents with ODD often benefit from a range of treatment methods used in combination.
