Oppositional Defiant Disorder (ODD) is a behavior disorder that is characterized by an ongoing pattern of uncooperative, defiant, hostile, and annoying behavior toward parents and others in a position of authority. ODD tends to occur in families with a history of Attention Deficit Disorder (ADD) or other behavioral problems. For many children, ODD improves over time, and follow-up studies have shown that the signs and symptoms of ODD resolve within 3 years in approximately 67% of children diagnosed with the disorder. However, research has also shown that approximately 30% of children with ODD eventually develop Conduct Disorder (CD), which is a more severe form of behavior disorder. The risk of developing CD is three times greater for children who were initially diagnosed with ODD at a very young age, such as preschool age. Therefore, it is important to seek treatment for ODD as soon as possible to prevent the development of more serious behavioral health problems and additional negative consequences.
