Economic Return on Investment of Parent Training Programmes for the Prevention of Child Externalising Behaviour Problems.

Economic models to inform decision-making are gaining popularity, especially for preventive interventions. However, there are few estimates of the long-term returns to parenting interventions used to prevent mental health problems in children. Using data from a randomised controlled trial evaluating five indicated parenting interventions for parents of children aged 5–12, we modeled the economic returns resulting from reduced costs in the health care and education sector, and increased long-term productivity in a Swedish setting. Analyses done on the original trial population, and on various sized local community populations indicated positive benefit–cost ratios. Even smaller local authorities would financially break-even, thus interventions were of good value-for-money. Benefit–cost analyses of such interventions may improve the basis for resource allocation within local decision-making. [ABSTRACT FROM AUTHOR]
