Long-Term Effects of a Multi-Component Community-Level Intervention to Reduce Single Vehicle Nighttime Crashes: Follow up Findings from a 24-Community Randomized Trial.
Objective: This follow up study examines whether a multi-component, high-visibility alcohol enforcement intervention implemented in 12 California cities had long-term effects on alcohol-related motor vehicle crashes beyond the time period of the original study. Previous results indicated a significant reduction in single vehicle nighttime (SVN) crashes among 15 to 30-year-olds in intervention cities relative to controls (Saltz et al., 2021).
Method: A randomized trial was conducted with 24 randomly chosen California cities from 2012 to 2017 to evaluate a multi-component intervention to reduce excessive drinking and driving while impaired among adolescents and young adults. Twelve of the cities were randomly assigned to the intervention condition and implemented high-visibility alcohol enforcement operations and other components from April 2013 to March 2016. Multi-level negative binomial regression analyses were conducted with motor vehicle crash data from 2010 to 2021 to examine whether single vehicle nighttime (SVN) crashes among 15 to 30-year-olds decreased in intervention cities relative to controls after the multi-component intervention was implemented. Analyses controlled for community sociodemographic characteristics, the overall time trend, the COVID pandemic, and pre-intervention levels of SVN crashes and adjusted for correlation of repeated observations within cities over time.
Results: Regression analyses indicated a significantly lower level of monthly SVN crashes among 15-to-30-year-olds in intervention cities during post-intervention months through 2021 relative to control cities [Event Rate Ratio (95%CI) = 0.88 (0.79, 0.98), p<.05] when controlling for community sociodemographic characteristics, the overall time trend, COVID, and pre-intervention levels of SVN crashes.
Conclusions: Study findings suggest that a multi-component, high-visibility alcohol enforcement intervention can have long-term effects on alcohol-related motor vehicle crashes and related injuries and fatalities among adolescent and young adult drivers.
期刊介绍：
The Journal of Studies on Alcohol and Drugs began in 1940 as the Quarterly Journal of Studies on Alcohol. It was founded by Howard W. Haggard, M.D., director of Yale University’s Laboratory of Applied Physiology. Dr. Haggard was a physiologist studying the effects of alcohol on the body, and he started the Journal as a way to publish the increasing amount of research on alcohol use, abuse, and treatment that emerged from Yale and other institutions in the years following the repeal of Prohibition in 1933. In addition to original research, the Journal also published abstracts summarizing other published documents dealing with alcohol. At Yale, Dr. Haggard built a large team of alcohol researchers within the Laboratory of Applied Physiology—including E.M. Jellinek, who became managing editor of the Journal in 1941. In 1943, to bring together the various alcohol research projects conducted by the Laboratory, Dr. Haggard formed the Section of Studies on Alcohol, which also became home to the Journal and its editorial staff. In 1950, the Section was renamed the Center of Alcohol Studies.
