 Attention deficit hyperactivity disorder ADHD and oppositional defiant disorder ODD are common childhood behavior disorders. Children with ADHD experience hyperactivity, distractibility, poor concentration, and impulsivity. If left untreated, ADHD can continue into adulthood, and can cause problems in family, social, and work environments. Children with ODD exhibit an ongoing pattern of uncooperative, defiant, and hostile behavior toward authority figures. Symptoms of ODD, including frequent temper tantrums, anger, resentment, and vindictiveness, may interfere with a childs everyday functioning. The Incredible Years parent training program has been shown to be effective in multiple settings at training parents to manage their childs behavior. This study will evaluate the effectiveness of the Incredible Years training program within a pediatric office setting at improving parenting skills and reducing behavioral symptoms in young children who are at risk for developing childhood behavior disorders.
