Evaluation of a Multi-Component Intervention to Reduce Harmful Alcohol Use and Related Harms in Multiple Cities

What this Trial Is About

This research aims to evaluate the effects of a multi-component intervention designed to reduce alcohol use and related harms such as motor vehicle crashes, fatalities, heavy or binge drinking, underage drinking, and drinking and driving. The study compares six intervention cities implementing these strategies with six matched cities that do not receive such interventions, with plans to expand to nine intervention and nine comparison cities. The intervention includes screening and brief interventions by health providers, enforcement of laws like drink-driving and underage drinking restrictions, and novel or partially tested approaches needing further evaluation. The intervention group cities receive a combination of strategies including screening and brief intervention by health providers, enforcement of existing alcohol policies, and new or partially tested interventions aimed at reducing harmful alcohol use. The comparison cities do not receive these evidence-based interventions. The study collects data over multiple years from both adults and youth through surveys and archival records to assess the impact of these interventions on alcohol-related harms and behaviors. Participants contribute through cross-sectional surveys conducted before and after the intervention to assess alcohol use behaviors, perceptions, and policy awareness. Researchers also collect archival data on incidents such as motor vehicle crashes, fatalities, violence, and injuries related to alcohol use. Key outcomes measured include health and social harms related to alcohol use over one year, heavybinge drinking, underage drinking, and attitudes towards alcohol policies. The study involves multiple years of follow-up and multi-level analyses to evaluate whether the intervention achieves at least a 10% reduction in harmful alcohol use.
