Summary

This report, commissioned by the National Highway Traffic Safety Administration (NHTSA), addresses the need for effective long-term prevention strategies to reduce alcohol-impaired driving. Motivated by the high societal costs of remediation and the irreversibility of injury or death, the study seeks to identify factors that contribute to the success of primary prevention programs. The authors argue that establishing societal norms against drunk driving requires evidence-based prevention strategies. To this end, the report conducts a meta-analysis of primary prevention studies from the public health field, excluding infectious diseases, to determine which intervention characteristics yield the greatest behavioral and attitudinal improvements. The methodology involved a meta-analysis of 37 controlled studies, from which 94 effect sizes were calculated. These effect sizes measured the difference between intervention recipients and control groups regarding outcome variables such as behavior, attitude, knowledge, or physical condition. The studies were coded for various features, including problem type (e.g., physical health, accidents, substance abuse), intervention type (e.g., technology, education, drugs), site of intervention, and frequency of contact. Statistical analyses, including cross-tabulations and stepwise linear regression, were employed to identify predictors of intervention success. Additionally, a prototype decision support system was developed to predict the likely benefit of potential interventions based on their features. The findings indicate that primary prevention interventions are generally effective, with recipients faring better than controls in 86% of comparisons. The median effect size was 0.6, meaning the average recipient performed better than 72% of the control group. Success varied significantly by problem area and intervention type. Programs addressing physical conditions or accidents yielded the highest benefits, while those targeting substance abuse or psychological deviance were less effective. Technological interventions and drug therapies produced the largest effect sizes, whereas education-only or information-only interventions performed poorly. However, combinations of interventions, particularly those mixing education and information, were highly successful. Regression analysis identified several key success factors: interventions were more effective when conducted outside of school settings, when they involved minimal demand on the subject’s existing habits, when they utilized multiple intervention types, and when the sample was not drawn from a high-risk population. Specifically for substance abuse prevention, success was associated with non-school sites and the avoidance of information-only strategies. The study concludes that primary prevention is a viable and logical basis for policies aimed at reducing drunk driving. It suggests that prevention programs should prioritize technological and pharmacological interventions or combined approaches rather than relying solely on education or information dissemination. Furthermore, the findings imply that interventions targeting general populations in non-school settings may be more effective than those focused on high-risk groups in schools. The report provides a foundation for designing prevention programs that maximize impact by leveraging these identified success factors, thereby supporting the NHTSA’s goal of long-term societal change regarding alcohol and driving.

Key finding

In 86 percent of comparisons, the average person receiving a primary prevention intervention fared better than the average control, with technological and combined interventions showing the highest effectiveness.
