Efficacies of the Incredible Years (IY) interventions are well-established in children with oppositional defiant disorder (ODD) but not among those with a primary diagnosis of attention-deficit/hyperactivity disorder (ADHD). We sought to evaluate 1-year follow-up outcomes among young children with ADHD who were treated with the IY interventions.…

The Incredible Years (IY) Series includes separate group interventions to improve parenting interactions, teacher classroom management, and child social-emotional regulation.

Among 30 families who received parent training, children's behavior improved significantly. Data showed significant increases in mothers' praises and reductions in mothers' negative behavior, children's non-compliance and deviance. Reductions in non-compliance and deviance were found 1-year later. Significantly more of the mother/child dyads who…

The Incredible Years parent and classroom interventions were evaluated for the first time in elementary schools. Culturally diverse, socioeconomically disadvantaged schools were randomly assigned to intervention or control (CON). In intervention schools, all children received a 2-year classroom intervention beginning in kindergarten. In addition,…

Evaluated long-term effectiveness of three cost-effective parent training programs for conduct-problem children. Assessed parents (N=154) one year posttreatment. Found significant improvements reported immediately posttreatment were maintained one year later. Found few differences between three treatment conditions excepting "consumer…

We examined parent and child moderators of outcome, program engagement effects, and predictors of engagement in the Incredible Years Parent Training Program. Head Start classrooms (N = 882 children) were randomly assigned to an intervention condition (that received the Incredible Years program) or to a control condition (that received usual Head…

Compared the effectiveness of individual therapy and therapist-led group therapy based on a videotape modeling program with mothers of 35 conduct-disordered children. Results showed both treatments offered equivalent and sustained improvement for parents and children, but the videotape modeling group format was more cost-effective. (JAC)

Seventy-eight families with child diagnosed as oppositional-defiant or conduct-disordered were randomly assigned to basic videotape parent skills training program (GDVM) with or without broader-based, videotape treatment component (ADVANCE). Both groups significantly improved at short-term follow-up. ADVANCE produced additional significant…

A study of 123 families examined the role of parental stress in physically abusive and nonabusive families with conduct-disordered children. Parental stress was found to play an important role in abusive families. Physically abusive families were found to have lower incomes, younger mothers with less education, a history of child abuse, and more…

Families of 159, 4- to 8-year-old children with oppositional defiant disorder (ODD) were randomly assigned to parent training (PT); parent plus teacher training (PT + TT); child training (CT); child plus teacher training (CT + TT); parent, child, plus teacher training (PT + CT + TT); or a waiting list control. Reports and independent observations…

Eleven centers were matched and assigned…
