The Incredible Years® (IY) Training Series is a set of three comprehensive, multifaceted, and developmentally based curricula for parents, teachers, and children. The program is designed to promote emotional and social competence and to prevent, reduce, and treat aggression and emotional problems in young children 0 to 12 years old. Young children with high rates of aggressive behavioral problems have been shown to be at great risk for developing substance abuse problems, becoming involved with deviant peer groups, dropping out of school, and engaging in delinquency and violence. Ultimately, the aim of the IY teacher, parent, and child training programs is to prevent and reduce the occurrence of aggressive and oppositional behavior, thus reducing the chance of developing later delinquent behaviors. The Incredible Years® Series has been tested in multiple randomized control studies with 2- to 12-year-old children diagnosed with conduct problems (i.e., having high rates of aggression, defiance, oppositional, and impulsive behaviors) and attention deficit disorder. It has also been evaluated as a prevention program with children 2 to 7 years old, who are at high risk by virtue of living in poverty. The baby program (6 weeks to 8 months) is currently undergoing evaluations. The Incredible Years® curricula may be implemented by schools, school districts, and related programs (including Head Start, day care, and kindergarten) as early prevention programs for teachers, parents, and children. Additionally, the child and parent programs may be used in mental health centers as a treatment for families with children who are diagnosed with Oppositional Defiant Disorder/Conduct Disorder (ODD/CD) and Attention Deficit Hyperactivity Disorder or for high risk families.
