Participatory learning was previously found to increase seat belt use by children. However, cross-cultural generalizability, effects of intervention beyond enhancing awareness, and risk factors for nonuse of seat belts, were not addressed. This study examined the effects of such an intervention on seat belt use, and addressed these issues in an Israeli kindergarten. One week, and 1 day before the intervention, 29 and 20%, respectively, of children were fastened by parents. Significant increases were seen 1 day (71%) and 1 month after the intervention (65%). The intervention's effects generalize to an Israeli sample, are not merely due to enhancing awareness, and maintain over time.
