Background: This paper reports on outcomes for the Incredible Years (IY) parent programme with parents of 8-13 year olds.
Method: The sample consisted of 280 parents of children at risk of adolescent antisocial behaviour, mean age 10.3 years.
Results: Paired t tests for both the per protocol (t(113) = 8.41, p < .001) and intention-to-treat (t(258) = 7.37, p < .001) data found significant improvements in child behaviour problems (ECBI). Statistically significant improvements were also found for parental depression and parenting skills.
Conclusions: The Incredible Years School Aged programme is effective in improving child behaviour, parenting competencies and parental mental health with parents of youngsters aged 8–13 years.
