 This long-term study has demonstrated the stability of positive intervention outcome for families within this disadvantaged, at-risk, population, using both self-report and objective observational data. The relatively low drop-out rate and high mean attendance reflects the effectiveness of the intervention in engaging typically hard-to-reach-families. Positive effects of the Incredible Years programme are maintained over time for many children and families who are in greatest need. Up to 40% of untreated children diagnosed with conduct disorders develop later problem behaviours including drug misuse, criminal and violent behaviour.
