Description:Objective
The Incredible Years® Series (IY®) intervention has demonstrated efficacy for reduction in conduct disorder (CD) symptomatology among clinically-affected youth in multiple randomized controlled trials (RCTs). Since children with family psychiatric histories of antisocial behavior are at markedly elevated risk for enduring symptoms of antisocial behavior (in comparison with their family-history-negative counterparts), we examined whether intervention effects across studies prevail in that subgroup or are relatively restricted to children without inferred risk.
Method
We conducted a re-analysis of 5 RCTs of IY® involving 280 clinically-affected children, 3–8 years of age, for whom family psychiatric history of externalizing behavior among first- and second-degree relatives was ascertained from at least 1 parent.
Results
IY® equally benefitted children with CD with and without family psychiatric histories of externalizing behavior. Both family psychiatric history of externalizing behavior and parental depressive symptomatology predicted higher severity of CD symptomatology at baseline.
Conclusion
The beneficial effects of IY® are evident among children with CD, irrespective of whether their conditions are more or less attributable to inherited susceptibility to enduring antisocial syndromes. A next phase of research should address whether earlier implementation of group-based education for parents of young children at elevated familial risk for antisocial behavior syndromes—prior to the development of disruptive patterns of behavior--would result in even more pronounced effects, and thereby constitute cost-effective, targeted preventive intervention for CD.
