Summary
This study, conducted by the Mid-America Research Institute and the University of North Carolina Highway Safety Research Center for the National Highway Traffic Safety Administration (NHTSA), aimed to develop and test media messages designed to deter drinking and driving (DWI) among young adults. Motivated by the slowing effectiveness of traditional deterrence strategies and the need to shift societal norms, the researchers targeted individuals aged 18–25, a demographic identified as high-risk for DWI incidents and potentially amenable to behavioral change. The project sought to create messages that would encourage anti-DWI norms rather than relying solely on fear of legal sanctions. The methodology involved a two-phase approach. First, pre-test focus groups were conducted in Boston, Massachusetts, and San Diego, California, with 65 participants segmented by gender and legal drinking age (18–20 and 21–25). These sessions identified attitudes toward drinking and driving and helped refine message concepts. Based on these findings, researchers developed six pilot messages in storyboard format, categorized into two themes: "consequences" (focusing on crash scenes and tragedy) and "intervention" (focusing on preventing friends from driving). Second, these six messages were pilot-tested in Overland Park, Kansas, and Wilmington, North Carolina, using focus groups and testing paths with 495 participants from the target demographic. Participants rated the messages on effectiveness, attention, and recall. The results indicated that message effectiveness was significantly influenced by the specific message content, the testing site, and the participant's gender. Messages focusing on "consequences" outperformed those focusing on "intervention," which participants found too "low key" and less engaging. Specifically, PSA 6 ("Karen and Beth"), a consequence-themed message with the tagline "Drinking and driving turns friends into killers," received the highest rankings for overall opinion, impact, and recall across both sites. PSA 2 ("The Emergency Room") and PSA 3 ("No Excuses") ranked second and third, respectively. While North Carolina participants generally reported stronger reactions to all messages than Kansas participants, the preference pattern remained consistent. Additionally, the messages were found to have a greater reported influence on young women than young men, with women also rating the messages as more attention-grabbing. Age did not significantly affect message reception. The study concludes that consequence-based messages, particularly those depicting emotional tragedy and peer impact, are more effective at engaging young adults than intervention-based approaches. However, the authors emphasize that no single message is sufficient to change behavior. Instead, these media efforts must be integrated into a comprehensive program that includes strong laws, enforcement, sure sanctions, and transportation alternatives. The findings suggest that targeting the 18–25 age group with norms-based messaging can bolster broader efforts to reduce DWI fatalities, provided the messages are part of a multi-faceted strategy.
Key finding
Messages depicting tragic consequences of drinking and driving were recalled and preferred more frequently than intervention-themed messages, with the highest-ranked message being effective across both underage and legal-age drinkers of both genders.
