Applying cost analysis methods to school-based prevention programs.

In order to efficiently allocate scarce prevention resources, policymakers need information about the economic costs of school-based substance use prevention programs. The objective of this paper is to outline economic cost analysis methods and demonstrate their applicability to school-based prevention programs. As an example, the paper focuses on estimating the economic cost of ALPHA, an intensive school-based substance use prevention program. The cost of ALPHA is compared to the costs of 3 elementary school programs that were alternatives to ALPHA. We collected cost information for 3 years, using a cost questionnaire that was completed by program and school budget officers and school principals. The program costs obtained from these sources were modified to conform to well-established economic cost analysis principles.
