BackgroundTo assess the effectiveness of a mobile injury prevention vehicle (mobile safety street [MSS]) with a hands-on curriculum on instruction and retention of safety knowledge compared with traditional classroom safety curriculum among grade 5 elementary school children.MethodsGrade 5 students (n = 1,692) were asked to participate in the study as either the intervention group (MSS experience) or the comparison group (traditional classroom safety curriculum). Each student in the intervention group was asked to complete a series of three surveys. The first survey was given before the MSS visit (Fall 2009), the second immediately following the MSS visit (Fall 2009), and a third given 6 months after the MSS visit (Spring 2010) to measure knowledge retention. Students in the comparison group were asked to complete two surveys. The first survey was given at the same time as the intervention group (Fall 2009) and the second was given after the completion of the traditional classroom safety curriculum (Spring 2010).ResultsStudents scored on average 5.67 of 10 (5.56-5.80) before any safety instruction was given. After MSS instruction, mean scores showed a significant increase to 7.43 of 10 (7.16-7.71). Such increase was still measurable 6 months after the intervention 7.34 (7.04-7.66). The comparison group saw a significant increase in their mean scores 6.48 (6.10-6.89), but the increase was much smaller than the intervention group.ConclusionsCommunity-based injury prevention programs are essential to reducing preventable injury and deaths from trauma. This study demonstrates that a hands-on program is more effective than traditional methods for providing safety knowledge.
