The Five "I" Framework of crash investigation: Linking investigation practices to safety reform.

Crash investigation is vital to the advancement of road safety, and it is a foundation for determining effective countermeasures and interventions for true road safety reform. However, the way in which road crash investigations are conducted substantially influences the quality of understanding and the effectiveness of responses. In crash investigations, we traditionally focus first on the question: "What caused this crash?" when it would be more efficient to ask immediately: "What could have prevented this crash?" or better yet, "What are all the ways this crash could have been prevented?" In this paper, we first explore a few common road crash investigation approaches where prosecution, retribution, or compensation are primary.

Advancing the theory and measurement of collective empowerment: a qualitative study.

Grounded Theory, a qualitative research method, was used to fully describe the construct of empowerment and its measurement in racially and ethnically diverse urban and rural neighborhoods. Forty-nine grass roots experts, primarily from six communities in Texas, participated via semi-structured interviews and focus groups. Observational data were also collected.

Effectiveness of primary enforcement safety belt laws and enhanced enforcement of safety belt laws: a summary of the Guide to Community Preventive Services systematic reviews.

Background: The use of safety belts is the single most effective means of reducing fatal and nonfatal injuries in motor-vehicle crashes. This paper summarizes the systematic reviews of two interventions to increase safety belt use: primary enforcement safety belt laws and enhanced enforcement of safety belt laws. The reviews were previously published in the American Journal of Preventive Medicine.
