这项随机对照试验评估了整合Steering Teens Safe的影响，这是一种家长沟通干预措施，具有来自车载视频记录系统的反馈。当车辆超过重力阈值时触发记录的车载视频系统已被用于向年轻驾驶员提供反馈。这些项目很少涉及父母的参与。父母-青少年二人组被随机分为三组，150对二人组完成了研究。所有组都收到了一个车载视频系统，记录驾驶事件。对照组没有收到任何反馈或干预。在第一个干预组中，青少年收到实时反馈，父母-青少年二元组收到基于车载系统记录的信息的摘要反馈。第二个干预组收到了同样的反馈，并向父母传授了改善与青少年安全驾驶沟通的策略。主要结果变量是每1000英里驾驶的不安全驾驶事件发生率，主要自变量是组分配。使用广义线性模型计算效应估计值。与对照组相比，事件记录反馈组的比率为0.35（95%CI = 0.24 - 0.50），联合干预组（事件记录反馈和父母沟通）的比率为0.21（95%CI = 0.15 - 0.30）。此外，联合干预组的事件发生率显著低于仅事件记录器反馈组（率比= 0.60，95% CI = 0.41 - 0.87）。虽然车载反馈系统可以帮助减少早期独立驾驶中的不安全驾驶事件，但教授父母与年轻驾驶员有效沟通的策略可能会进一步提高影响力。
This randomized controlled trial evaluated the impact of integrating Steering Teens Safe, a parent communication intervention, with feedback from an in-vehicle video recording system. In-vehicle video systems that trigger a recording when the vehicle exceeds a g-force threshold have been used to provide feedback to young drivers. Few of these programs have involved parental engagement. Parent-teen dyads were randomized to three groups and 150 dyads completed the study. All groups received an in-vehicle video system that recorded driving events. The control group received no feedback or intervention. In the first intervention group, teens received real-time feedback, and parent-teen dyads received summary feedback, based on information recorded by the in-vehicle system. The second intervention group received the same feedback, plus parents were taught strategies to improve communication with their teen about safe driving. The primary outcome variable was unsafe driving event rates per 1000 miles driven and the primary independent variable was group assignment. Generalized linear models were used to calculate effect estimates. Compared with the control group, the Event Recorder Feedback group had a rate ratio of 0.35 (95% CI = 0.24 – 0.50) and the combined intervention group (Event Recorder Feedback and parent communication) had a rate ratio of 0.21 (95% CI = 0.15 – 0.30). Furthermore, the combined intervention group had a significantly lower event rate than the Event Recorder Feedback only group (rate ratio = 0.60, 95% CI = 0.41 – 0.87). While in-vehicle feedback systems can help reduce unsafe driving events in early independent driving, teaching parents strategies for effective communication with their young driver may further improve impact.
