Gerene Denning, of the University of Iowa Department of Emergency Medicine, presented this at CPSC’s ATV Safety Summit Oct. 11, 2012. The study objective was to determine the effectiveness of an in-classroom ATV safety education program that targets younger adolescents and highlights the 10 STARs --Safety Tips for ATV Riders. Methods: An audience response system was utilized to obtain data before and after the educational sessions. A one year follow-up written survey was administered. Results: About 2000 students in thirteen Iowa schools received the ATV safety program; 10 schools participated in the follow-up study. On the three knowledge questions, pre-intervention correct scores were 52%, 27% and 46% which rose to 93%, 80% and 79% on post-exam, respectively. Immediately after the program, 44% said they were likely or very likely to use the ATV safety tips, while 36% said they were unlikely or very unlikely to do so. One-year follow-up knowledge question scores were 77%, 45% and 58%. Lower percentages of students reported having ridden on an ATV with passengers or on a public road in the year following the education program. There were no differences in helmet use. Conclusion: Although it's unclear if ATV safety behavior definitely improved, the classroom educational intervention was able to increase short and long term safety knowledge. Repeated interventions may improve both knowledge retention and safety behaviors.
