项目摘要

PROJECT SUMMARY Bicycling is a leading cause of childhood injuries and, second to motor vehicles, bicycles contribute to more childhood injuries than any other consumer product. Approaches to increasing bicycling safety among youth include bicycle safety education programs and parents also play a vital role as influencers of their child's bicycle handling and traffic safety skills, perceptions, and self-efficacy. Bicycle safety education programs are abundant, but little is known about their effectiveness in terms of behavior change. This cluster randomized controlled trial will evaluate a community-based bicycle safety education program with and without an in- person parent training component. We will recruit 180 early adolescent bicyclists (ages 9 to 12) and a parent/guardian from local neighborhood centers after school and summer programs, where we have conducted preliminary studies. Randomization into the three study groups will occur at the site-level. Adolescent bicycles in all study group sites will be equipped with Pedal Portal, an innovative bicycle-mounted GPS/video system developed by our research team to objectively observe bicycling risk exposure and behaviors while bicycling. System data will be coded to measure bicycling exposure (hours, miles traveled, routes) and the types and rates of safety-relevant events (near crashes, crashes), and safety-relevant behaviors (e.g., following traffic rules, scanning for traffic at intersections). This will be the first randomized trial to use GPS and video technology to evaluate the effectiveness of a youth bicycle safety intervention in changing behavior. The control group will not receive any bicycle safety education programming. Participants in the first intervention group (Bike Club) will receive a 12-hour bicycle safety education program. Participants in the second intervention group (Bike Club Plus) will receive an enhanced version of the 12-hour bicycle safety education program which will include a parent training session on bicycling safety best practices, child development as it relates to bicycling, strategies for practice at home, and feedback on their adolescent's bicycling performance. Our main hypotheses are that adolescents who receive the bicycle safety intervention will have increased safety behaviors (e.g., helmet use, hazard recognition), reduced errors (e.g., riding against traffic, swerving/wobbling), and increased knowledge, perceptions, and self-efficacy compared to the control group; and adolescents whose parent receives the parent training will have even greater improvements in study outcomes than those whose parents do not receive the training. If successful, approaches from this study could be widely implemented to improve adolescent bicycling safety.

项目摘要骑自行车是儿童伤害的主要原因，其次是汽车，自行车有助于更多儿童伤害比任何其他消费者产品。青年人增加骑自行车安全的方法包括自行车安全教育计划和父母作为孩子的影响者发挥着至关重要的作用自行车处理和交通安全技能，看法和自我效能感。自行车安全教育计划是丰富，但对它们在行为改变方面的有效性知之甚少。此群集随机对照试验将评估一个基于社区的自行车安全教育计划，没有或没有人父母培训部分。我们将招募180名青少年骑自行车的人（9至12岁）和放学后的当地社区中心的家长/监护人，我们有进行了初步研究。将三个研究组的随机分配在现场级别。所有研究小组网站的青春期自行车都将配备踏板门户，这是一个创新的自行车安装 GPS/视频系统由我们的研究团队开发，目的是客观地观察骑自行车的风险敞口和骑自行车时的行为。系统数据将进行编码以测量骑自行车的曝光（小时，旅行的里程，路线）以及与安全相关的事件的类型和速度（坠机事故，撞车事故）和安全与安全相关行为（例如，遵循流量规则，在交叉点扫描流量）。这将是第一个随机试验使用GP和视频技术评估青年自行车安全干预的有效性改变行为。对照组将不会收到任何自行车安全教育计划。参与者在第一个干预小组（自行车俱乐部）中，将获得12小时的自行车安全教育计划。参与者在第二个干预组（Bike Club Plus）中，将获得增强的12小时自行车的版本安全教育计划将包括有关骑自行车安全最佳实践的家长培训课程，儿童与骑自行车，在家练习策略有关的发展以及对青少年的反馈骑自行车的性能。我们的主要假设是接受自行车安全干预的青少年安全行为将提高（例如使用头盔，危险识别），误差减少（例如，骑行与对照相比团体;和父母接受父母培训的青少年将有更大的改善与父母没有接受培训的结果相比，学习成果。如果成功的话，从中迈进了可以广泛实施研究以提高青少年骑自行车的安全性。
