Summary
This 1987 report by the National Highway Traffic Safety Administration evaluates the effectiveness of Health Risk Appraisal (HRA) programs in increasing safety belt use. The study was motivated by a gap in existing literature, which relied exclusively on self-reported data and lacked rigorous observational verification of behavior change. Additionally, while previous studies suggested HRA could improve safety belt use by up to 23 percent, there was a need to determine if supplemental educational materials could enhance these effects, particularly in both mandatory and voluntary safety belt settings. The primary objective was to assess whether HRA programs, with and without specific educational supplements, could produce significant increases in both claimed and observed safety belt use. The researchers developed a supplemental educational package called "The Great American Habit Plan" (GAHP), grounded in behavior change theory, to complement standard HRA interventions. Field tests were conducted in work and medical settings across four states: Pennsylvania, Illinois, Arizona, and California. The experimental design compared treatment groups receiving HRA alone against those receiving HRA combined with the GAHP materials, alongside control groups. Data collection involved both self-reported surveys and direct observational studies to verify actual safety belt usage. This approach allowed for a comparison of effectiveness across different environments and legislative contexts, addressing the need to validate self-reported claims with empirical observation. The analysis yielded strong findings supporting the hypothesis that HRA programs can produce positive behavior changes regarding safety belt use. The study confirmed that HRA, particularly when enhanced with the GAHP educational materials, was effective in increasing safety belt usage. The educational materials were rated as highly useful by HRA program providers, serving as a valuable complement to standard risk assessment information. The results indicated that personalized health risk information, when paired with targeted educational interventions, successfully motivated individuals to adopt safer driving habits. The observational data helped bridge the gap between self-reported intentions and actual behavior, providing more robust evidence of the intervention's impact than previous studies. The significance of this research lies in its validation of HRA as a viable tool for traffic safety promotion, extending its utility beyond traditional medical risk factors like smoking or blood pressure. The findings suggest that integrating traffic safety education into broader health promotion programs can effectively increase safety belt compliance. This approach offers a method for achieving higher usage rates than those attainable through legislation alone, particularly in voluntary settings or to sustain gains in mandatory states. The report provides actionable insights for safety program administrators, public health officials, and HRA vendors, demonstrating that personalized, theory-based educational supplements can significantly enhance the behavioral outcomes of health risk appraisal programs.
Key finding
Health risk appraisal programs produce significant increases in safety belt use, and supplemental educational materials are considered highly useful by providers to enhance this effect.
