Because it is a behavioral condition, behavior modification is the most effective (and most widely used) treatment for oppositional defiant disorder (ODD). A therapist or psychologist who specializes in treating children will manage the family counseling used to treat ODD. However, in some cases medication may be necessary. This is often true when ODD occurs together with other conditions, such as attention-deficit/hyperactivity disorder (ADHD) or depression. In some cases, the symptoms of ODD are actually related to depression. When this is the case, appropriate treatment and medication for the depression is required.
