Identification of Appropriate Investment Levels to Improve and Maintain Seat Belt Usage Rates in the State of Colorado

摘要

The study was designed to gather data from both primary and secondary states regarding investments in informational and educational messages on the use of seat belts. This investment data was correlated to seat belt usage rates. Within secondary states, the coefficient of determination was .99, indicating that most of the variability in usage rate change was due to the investments made in media and educational campaigns. While the coefficient of determination was much lower for primary states (.46 vs .99), the average seat belt usage rate is 11 percent higher. This suggests that the law itself as well as other variables has more to do with changes in usage rate in primary states.
