Fergusson, David M.; Stanley, Lesley; Horwood, L. John
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 Au: (abstract objective) please confirm change of IYBPP definition to 'Incredible Years Basic) 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.
