The research evaluating the effects of programs and policies in reducing the incidence of alcohol problems is critically reviewed. Four types of preventive interventions are examined including: (1) policies affecting the physical, economic and social availability of alcohol (e.G. Minimum legal drinking age, price and advertising of alcohol), (2) formal social controls on alcohol-related behavior (e.G.Drinking-driving laws), (3) primary prevention programs (e.G., School-based alcohol education), and (4) environmental safety measures (e.G., Automobile airbags). The research generally support the efficacy of 3 alcohol-specific policies: raising the minimum legal drinking age to 21, increasing alcohol taxes and increasing the enforcementof drinking age to 21, increasing alcohol taxes and increasing the enforcement of drinking-driving laws. Also, research suggests that various environmental safety measures reduce the incidence of alcohol-related trauma. In contrast, little evidence currently exists to support the efficacy of primary prevention programs. However, a systems perspective of prevention suggests that prevention programs may become more efficacious after widespread adoption of prevention policies that lead to shifts in social norms regarding use of beverage alcohol.
