Summary

This study addresses the need to improve traffic safety communication campaigns by grounding them in established behavior change theories. While such theories have successfully promoted health behaviors like smoking cessation and exercise, their application in traffic safety campaigns for distracted and alcohol-impaired driving remains underexplored. The research aimed to identify which behavior change theories are present in existing campaigns and to understand how State Highway Safety Offices develop these initiatives, with the goal of enhancing campaign effectiveness through theoretical alignment. The methodology involved three primary components. First, an extensive literature review identified 29 behavior change theories applicable to traffic safety. Second, researchers conducted an internet search to identify active campaigns, resulting in a sample of 16 distracted driving campaigns and 13 alcohol-impaired driving campaigns. These campaigns were selected based on criteria including active websites, specific target audiences, English-language content, and multi-channel outreach. An expert panel comprising specialists in traffic safety, cognitive social psychology, and communications assessed each campaign to determine which of the 29 theories were observed, regardless of whether the application was intentional. Third, interviews were conducted with nine representatives from five State Highway Safety Offices to gather insights on campaign development processes, decision-making, and evaluation practices. The results revealed that most campaigns aligned with at least one theory, with an average of two theories observed per campaign (range: 0–8). However, 12 of the 29 identified theories were not observed in any of the 29 campaigns examined. The Information-Motivation-Behavioral Skills Model was the most frequently observed theory, appearing in 16 campaigns, and its construct of "information" (facts and statistics) was the most common element, found in 25 campaigns. Other frequently observed theories included the Extended Parallel Process Model, Health Belief Model, Deterrence Theory, and Social Cognitive Theory. The "Faces of Drunk Driving" campaign exhibited the highest theoretical diversity with eight observed theories, while the "X the TXT" campaign exhibited the lowest with zero theories and only one construct. Interviews indicated that state personnel did not intentionally use behavior change theories; instead, campaigns were developed based on judgment and opportunistic components rather than comprehensive planning. The study concludes that there is a significant opportunity to intentionally apply behavior change theories during campaign design to improve effectiveness. Although no single theory was deemed exclusively useful, the findings suggest that integrating theoretical frameworks into the planning, development, and evaluation of safety messages could enhance their impact. The authors recommend that jurisdictions and funding sources recognize the value of theory-based approaches, emphasizing the importance of audience segmentation and careful consideration of message source, content, and delivery. This research provides a foundation for developing more robust, evidence-based strategies to combat risky driving behaviors.

Key finding

The information-motivation-behavioral skills model was the most frequently observed behavior change theory in the examined campaigns, although state officials generally did not intentionally apply behavior change theories during campaign development.
