title: Preliminary data on the efficacy of the Incredible Years Basic Parent Programme in New Zealand.
abstract: OBJECTIVE
  The aim of the present study was to conduct a preliminary examination of the efficacy and cultural acceptability of the Incredible Years Basic Parent Programme (IYBPP) using data provided by the New Zealand Ministry of Education.
  
  
  METHODS
  Data were gathered on a series of 214 parents attending IYBPP for at least nine sessions. These data included (i) pre-test and post-test T scores on the Eyberg intensity and problem scales; (ii) pre-test and post-test scores on the parent version of the child Social Competence Scale; and (iii) parent satisfaction ratings.
  
  
  RESULTS
  Pre-test-post-test comparisons indicated significant improvements in behaviour and social competence scores (p<0.001). Effect sizes ranged from 0.50 to 0.77. Effects were similar for Maori and non-Maori subjects. Parental satisfaction with the programme was high, with Maori and non-Maori parents reporting similar levels of satisfaction.
  
  
  CONCLUSIONS
  These preliminary data are consistent with the view that IYBPP is an effective and culturally appropriate programme. There is a need for a more comprehensive evaluation using pilot research to assess the fidelity of programme delivery and randomized trials to assess programme efficacy.
