Evaluation of Global Smart Drinking Goals Initiative (GSDG)

This study will evaluate effects of a multi-component, population-level intervention on alcohol use and related harms in six intervention cities relative to six matched comparison cities. Intervention components include screening and brief interventions by health providers, other evidence-based interventions (e.g., enforcement of drink-driving or underage drinking laws), and novel or partially tested interventions that warrant further evaluation. Key outcomes of interest include alcohol-related harms such as alcohol-related motor vehicle crashes and fatalities, heavy/binge drinking, underage drinking, and drinking and driving.

This study will evaluate effects of a multi-component, population-level intervention on alcohol use and related harms in six intervention cities relative to six matched comparison cities. The trial is expected to expand to nine intervention and nine comparison cities in 2018. Intervention components include screening and brief interventions by health providers, other evidence-based interventions (e.g., enforcement of drink-driving or underage drinking laws), and novel or partially tested interventions that warrant further evaluation. Key outcomes of interest include alcohol-related harms such as alcohol-related motor vehicle crashes and fatalities, heavy/binge drinking, underage drinking, and drinking and driving. Multiple years of pre- and post-intervention survey data will be collected from cross-sectional samples of adults and youth in each city to assess intervention effects on harmful alcohol use. Multiple years of archival data will also be collected from each city to assess intervention effects on alcohol-related harms such as motor vehicle crashes and fatalities, violence and unintentional injuries. Multi-level analyses will be conducted with data for the total sample of 18 cities and for each pair of cities to determine whether the overall goal of reducing harmful alcohol use by at least 10% is achieved.

Cities receiving a multi-component intervention, including screening and brief intervention, other evidence-based interventions (e.g., enforcement of drink-driving or underage drinking laws), and novel or partially tested interventions that warrant further evaluation.

Knowledge of policies such as the minimum legal drinking age and maximum allowable blood alcohol concentration limit for driving

Perceived likelihood of being asked for age identification, being stopped by police for drinking and driving, etc.

Self-reported knowledge of possible chronic health-related consequences of alcohol use (e.g., liver cirrhosis, coronary heart disease)

Self-reported consumption (quantity and frequency) of no-alcohol and low-alcohol beer, no-alcohol and low-alcohol beer sales, underage use of no-alcohol and low-alcohol beer
