This study examined parental perceptions of the benefits and barriers to bicycle helmet use and their level of knowledge about bicycle safety issues. A school-based bicycle safety education program was taught to first- and second-grade students in a rural/suburban school district by a graduate nursing student. Pender's Health Promotion Model was the theoretical framework used to guide this research study. A parent Bicycle Helmet Questionnaire (BHQ) developed by the author was the tool used to gather data. The study determined that parents of children in schools that received the educational intervention prior to completing the questionnaire had significantly higher knowledge level scores and that the majority of parents were in favor of bicycle helmet legislation for children. The implications from this research study include the importance of bicycle safety education interventions for students and parents and the need to implement bicycle helmet legislation.
