Estimating the costs of preventive interventions

The goal of this article is to improve the practice and reporting of cost estimates of prevention programs. It reviews the steps in estimating the costs of an intervention and the principles that should guide estimation. The authors then review prior efforts to estimate intervention costs using a sample of well-known but diverse studies. Finally, the authors illustrate the principles with an example, the Family Bereavement Program. They conclude that example by discussing whether and how the costs of the intervention might differ when implemented in a real-world setting.
