A National Cost Analysis of Community Interventions to Prevent Underage Drinking and Prescription Drug Misuse.

This prospective cost analysis addresses a gap in the prevention literature by providing estimates of the typical real-world costs to implement community interventions focused on preventing underage drinking and prescription drug misuse. The study uses cost data reported by more than 400 community subrecipients participating in a national cross-site evaluation of the Substance Abuse and Mental Health Services Administration's Strategic Prevention Framework Partnerships for Success grant program during 2013-2017. Community subrecipient organizations completed an annual Web-based survey to report their intervention costs. The analysis compares the relative startup and annual ongoing implementation costs of different prevention strategies and services. Partnerships for Success communities implemented a wide variety of interventions. Annual ongoing implementation was typically more costly than intervention startup. Costs were generally similar for population-level interventions, such as information dissemination and environmental strategies, and individual-level interventions, such as prevention education and positive alternative activities. However, population-level interventions reached considerably more people and consequently had much lower costs per person. Personnel contributed the most to intervention costs, followed by intervention supplies and overhead. Startup costs for initial training and costs for incentives, ongoing training, and in-kind contributions (nonlabor) during ongoing implementation were not typically reported. This study informs prevention planning by providing detailed information about the costs of classes of interventions used in communities, outside of research settings.
