**Summary of Meta-Analysis Examining the Incredible Years® Parent Programs**

*Written by Carolyn Webster-Stratton*

A new meta-analysis paper has just been published by a Dutch team. This review examines the effectiveness of the Incredible Years® parent training to reduce disruptive behavior and promote social competence in children.  Fifty studies were conducted where the Incredible Years® parent program was compared with a comparison control group by various researchers. Findings indicate that the **Incredible Years® program is successful in improving child behavior, particularly for the most severe cases,** and with a diverse range of families in different contexts.  The parent program is considered by this review to be well-established. *These positive findings which are comparable across a range of studies may be interesting for policymakers, agencies and practitioners.  *  
 Take a look at this meta-analysis which separates prevention from treatment studies and assesses intervention, child and family characteristics, and effect sizes for different outcomes. **Number of sessions attended by parents was positively related to intervention effects.**  
 The authors write, “The Incredible Years® program might have capacity to be tailored to specific characteristics and needs of families in spite of being manualized group training. Group leaders can achieve flexible applications of the manual and help parents learn to use the parenting principles to achieve their own determined goals.”
