Abstract

Background Public policy can limit alcohol consumption and its associated harm, but no direct comparison of the relative efficacy of alcohol control policies exists for the U.S. Purpose To identify alcohol control policies and develop quantitative ratings of their efficacy and strength of evidence. Methods In 2010, a Delphi panel of ten U.S. alcohol policy experts identified and rated the efficacy of alcohol control policies for reducing binge drinking and alcohol-impaired driving among both the general population and youth, and the strength of evidence informing the efficacy of each policy. The policies were nominated on the basis of scientific evidence and potential for public health impact. Analysis was conducted in 2010-2012. Results Panelists identified and rated 47 policies. Policies limiting price received the highest ratings, with alcohol taxes receiving the highest ratings for all four outcomes. Highly rated policies for reducing binge drinking and alcohol-impaired driving in the general population also were rated highly among youth, although several policies were rated more highly for youth compared with the general population. Policy efficacy ratings for the general population and youth were positively correlated for reducing both binge drinking (r=0.50) and alcohol-impaired driving (r=0.45). The correlation between efficacy ratings for reducing binge drinking and alcohol-impaired driving was strong for the general population (r=0.88) and for youth (r=0.85). Efficacy ratings were positively correlated with strength-of-evidence ratings. Conclusions Comparative policy ratings can help characterize the alcohol policy environment, inform policy discussions, and identify future research needs.
