Cost-effectiveness of Legacy for Children™ for Reducing Behavioral Problems and Risk for ADHD among Children Living in Poverty.

This paper describes the programmatic costs required for implementation of the Legacy for Children™ (Legacy) program at two sites (Miami and Los Angeles) and enumerate the cost-effectiveness of the program. Legacy provided group-based parenting intervention for mothers and children living in poverty. This cost-effectiveness analysis included two behavioral outcomes, behavioral problems, and attention-deficit/hyperactivity disorder (ADHD), and programmatic costs collected prospectively (2008 US$). Incremental costs, effects, the incremental cost-effectiveness ratio (ICER), and cost-effectiveness acceptability curves were estimated for the intervention groups relative to a comparison group with a 5 year analytic horizon. The intervention costs per family for Miami and Los Angeles were $16,900 and $14,100, respectively. For behavioral problems, the incremental effects were marginally significant (p=0.11) for Miami with an ICER of $178,000 per child at high risk for severe behavioral problems avoided. For ADHD, the incremental effects were significant (p=0.03) for Los Angeles with an ICER of $91,100 per child at high risk for ADHD avoided. Legacy was related to improvements in behavioral outcomes within two community-drawn sites and the costs and effects are reasonable considering the associated economic costs.
