A growing body of research provides evidence of the prevalence of childhood conduct problems and the long-term negative consequences that result. It also identifies parent management training such as the Incredible Years Parenting (IYP) programme as an effective evidence-based treatment. ?? As part of the Drivers of Crime work programme the Ministries of Education, Health and Social Development established a pilot study of the IYP programme to assess the effectiveness of this programme in reducing conduct problems in a New Zealand context. ?? The project was influenced by the recommendations of the Government Advisory Group on Conduct Problems, the Ministry of Education Positive Behaviour for Learning strategy and the desire to develop a new collaborative model to evaluate government-funded programmes. The benefits of the IYP training were broadly similar for M?ori and non-M?ori families. Both M?ori and non-M?ori parents expressed high to moderate satisfaction with the programme. These results suggest the IYP programme can be successfully implemented in New Zealand and retain its general level of effectiveness.
