项目摘要

DESCRIPTION (provided by applicant): Cell phone use while driving is prevalent among young drivers. The risk of crashing is 4 times higher for drivers talking on the phone, and 23 times higher for those texting. Drivers aged 18-20 years have both the highest phone use while driving and the highest crash rate per capita among all ages. Unfortunately, educational efforts and legislative bans have not been effective in reducing phone use while driving, highlighting the need to explore other interventions. While technological solutions, including phone apps, may offer promising alternatives, research remains sparse. Specifically, there are to date no studies of the use of phone apps or other technological interventions to reduce phone use by high-risk young adults while driving. Therefore, we propose an R21 project with objectives to pilot test the feasibility and preliminary efficacy of a phone app for reducing phone use and high-risk driving events in drivers aged 18-20 years. We hypothesize that it is feasible to implement a cell phone app intervention among West Virginia University drivers. We also hypothesize that the cell phone use and high-risk driving events can be substantially reduced, if a phone app which limits cell phone use is active, and young drivers comply with it. The aims of this project are to test the feasibility of a cell phone app intervention on acceptance and retention, and identify facilitators and barriers for compliance (Aim 1), and to determine whether a phone app intervention reduces calling, texting, and high-risk driving events among drivers aged 18-20 years (Aim 2). A prospective, randomized, parallel-group, exploratory, three-arm trial will be conducted. Sixty students at West Virginia University will be randomized to receive: (1) a TXTL8R app with passenger override mode that blocks phone use while driving, but allows the use of the phone after pressing the passenger button; (2) a TXTL8R app without passenger override mode that blocks cell phone use when the phone is moving above a threshold speed; or (3) a sham app that allows and tracks calls and texts while driving. Participants will be studie for six months. The app will be set active in blocking phone use for four months, and inactive for the remaining two months for the intervention arms. The outcomes will include: (1) calling while driving; (2) texting while driving; (3) high-risk driving events as measured by an event-triggered accelerometer. We will conduct process evaluation and estimate preliminary efficacy of cell phone app in reducing calling, texting, and high-risk driving events. Guided by preliminary data, this study is also innovative. For example, we focus on an innovative technological approach for addressing the epidemic of driver phone use. We will employ novel video capture methods to identify high-risk driving events and assess the contribution of phone use to high-risk driving events. This study is significant, because the findings will provide preliminary data for a larger scale trial (R01 project) to investigate more definitively the efficacy of a phone app for reducing cell phone use, high-risk driving behaviors, and crashes in young adults.

描述（由申请人提供）：开车时使用手机在年轻驾驶员中很常见，打电话的驾驶员发生车祸的风险高出 4 倍，发短信的驾驶员则高出 23 倍。不幸的是，教育工作和立法禁令并没有有效减少开车时使用手机，这凸显了探索其他干预措施（包括手机应用程序）的必要性。可能会提供具体而言，迄今为止还没有关于使用手机应用程序或其他技术干预措施来减少高风险年轻人在驾驶时使用手机的研究。因此，我们提出了一个旨在进行试点测试的 R21 项目。手机应用程序减少 18-20 岁司机使用手机和高风险驾驶事件的可行性和初步效果我们还发现，在西弗吉尼亚大学司机中实施手机应用程序干预是可行的。手机的使用和高风险驾驶事件可以如果限制手机使用的手机应用程序处于活动状态，并且年轻驾驶员遵守该应用程序，则可以大幅减少。该项目的目的是测试手机应用程序干预接受和保留的可行性，并确定促进因素和障碍。合规性（目标 1），并确定手机应用程序干预是否减少 18-20 岁驾驶员的通话、短信和高风险驾驶事件（目标 2）。手臂试验将是西弗吉尼亚大学的 60 名学生将被随机接收：(1) 具有乘客优先模式的 TXTL8R 应用程序，该应用程序会阻止在驾驶时使用手机，但在按下乘客按钮后允许使用手机；(2) TXTL8R 应用程序。没有乘客超越模式，当手机移动速度超过阈值时，该应用程序将被设置为活动状态；或（3）允许并跟踪驾驶时的通话和短信的虚假应用程序。阻止手机使用干预组在四个月内处于不活动状态，并且在剩余两个月内不活动，结果将包括：(1) 开车时打电话；(3) 开车时发短信；(3) 通过事件触发来衡量的高风险驾驶事件。我们将在初步数据的指导下，对手机应用程序在减少打电话、发短信和高风险驾驶事件方面进行过程评估和初步效果，例如，我们关注的是一种创新的技术方法。解决司机使用手机的流行问题。将采用新颖的视频捕捉方法来识别高风险驾驶事件并评估手机使用对高风险驾驶事件的影响这项研究意义重大，因为研究结果将为更大规模的试验（R01项目）提供初步数据以进行调查。更明确地显示手机应用程序在减少年轻人使用手机、高风险驾驶行为和车祸。
