Summary
This 1995 report by the National Highway Traffic Safety Administration evaluates the impact of youth peer-to-peer programs, specifically Students Against Driving Drunk (SADD), on high school students’ attitudes, behaviors, and crash rates. The study was motivated by the persistence of underage drinking and impaired driving despite widespread legislation and prevention efforts. With over 16,000 SADD chapters in U.S. high schools, the research aimed to determine whether these peer-led initiatives effectively reduce alcohol-related risks or merely serve as one component of a broader community strategy. The researchers employed a comparative design involving twelve high schools across Arizona, Ohio, and Wisconsin—states with strict zero-tolerance laws for underage drivers. Six schools with highly active, exemplary SADD chapters were matched with six similar comparison schools lacking such programs. Data collection included focus groups with SADD members, school-wide surveys of 17,484 students conducted in 1994 and 1995, and an analysis of police-reported crash data for the surrounding communities. The surveys assessed student awareness, attitudes toward drinking and driving, self-reported behaviors, and exposure to anti-alcohol activities. The findings revealed that SADD programs significantly influenced the school environment and student attitudes. Students in SADD schools reported substantially greater exposure to anti-drinking and driving information through various channels, such as assemblies and posters. Attitudinally, these students were more likely to believe that non-alcoholic parties could be enjoyable and that parents would be upset by underage drinking. Conversely, they were less likely to condone underage drinking if driving was not involved or to rely solely on fear of arrest as a deterrent. However, the study found no consistent statistically significant differences between SADD and comparison schools regarding self-reported drinking, driving after drinking, or the use of false identification. Similarly, police-reported crash data for 16- and 17-year-old drivers showed no conclusive reduction in crash involvement in SADD communities, although trends generally favored SADD areas. The authors conclude that while vigorous peer-to-peer programs like SADD provide valuable benefits to members and positively shift the attitudes of the broader student body toward prevention, they do not independently produce measurable reductions in drinking behaviors or crash rates. The study suggests that such programs should not be viewed as standalone solutions but rather as important components of a comprehensive community strategy that integrates education, enforcement, and rehabilitation to address underage drinking and impaired driving.
Key finding
Students in schools with active peer-to-peer programs reported more positive attitudes against underage drinking but showed no consistent statistically significant reduction in self-reported drinking and driving behaviors or police-reported crashes compared to schools without such programs.
