The Incredible Years Parent Training Programmes were first recommended by the American Psychological Association Task Force (Brestan & Eyberg, 1998) as meeting the stringent “Chambless & Hollon criteria” (1998) for empirically supported mental health intervention for children with conduct problems.

In the last decade, the Incredible Years programmes have been given designations such as: “Exemplary”, “Promising”, “Proven” and “Model” in review groups such as OJJDP, SAMHSA’s NREPP, Promising Practices Network, Blueprints for Health Youth Development and United Nations Office on Drugs and Crime. Typically, these review groups require the following to be classified as evidence-based: (1) statistical significance in at least two randomised control group trials using reliable and valid outcome assessment measures; and (2) replications by an independent evaluator.

As part of the Drivers of Crime work programme the Ministries of Education, Health and Social Development established a pilot study of the Incredible Years Parent (IYP) programme to assess its effectiveness in reducing conduct problems in a New Zealand context.
The New Zealand Incredible Years Pilot Study provided evidence to suggest that IYP, a programme developed overseas, can be successfully implemented in New Zealand and retain its general level of effectiveness for both Māori and non-Māori families.
The follow-up study investigated the long-term outcomes for 136 (82%) of the 166 children and parents who were in the original sample.
