This study analyzed the impact of a combination of approaches on the frequency of seat belt usage in a large Hispanic community in western Michigan. Subjects in either a treatment or a no-treatment control condition were observed weekly for seat belt usage while arriving at church over several months. They were observed for four weeks prior, during and after an intervention program. Subjects in treatment condition attended weekly group meetings where they viewed seat belt use promotion videos, publicly signed behavioral contracts agreeing to use their seat belts, and received permanent prompts which were installed on the dashboard of their cars. A four week follow up was conducted four months after the installation of the permanent prompt.

The treatment effect was maintained at a statistically significant level throughout treatment, after treatment and at four months follow up.
