简要总结
The purpose of this study is to test the effects of an in-vehicle driving feedback technology, with and without parent communication training, on risky driving events, unsafe driving behaviors, and subsequent traffic violations among teens who have recently received a moving traffic violation.
详细描述
For this study, 240 teen and parent/guardian dyads will be randomized into one of three study groups for six months. Teens will be aged 16-17 who committed a moving-related traffic violation and their parent/legal guardian who is most involved with their driving. Researchers will aim to determine the effects of the intervention on teens' risky driving events, unsafe driving behaviors, and traffic violation recidivism. Additionally, researchers will aim to determine the effects of the intervention on frequency and quality of parent-teen communications about safe driving practices.

研究组 & 干预措施
Control Group
The Control Group will have the in-vehicle device installed in the teen's car, but all feedback features will be disabled.
Feedback Only Group
The Feedback Only Group will have the in-vehicle devices in the teen's car and download the smartphone app on the teen's smartphone. Researchers will provide instructions on how teens can review their driving data. Teens will also receive biweekly cumulative driving reports.
干预措施: In-vehicle device (Combination Product)
Feedback and Parent Communication Group
The Feedback and Parent Communication Group will have the in-vehicle devices in the teen's car and download the smartphone app on the teen's smartphone. Researchers will provide instructions on how teens and parents can review their driving data. The parent will also receive communication training on how to motivate their teen to adopt safe driving habits via online modules and a video call with a motivational interviewing professional. A second booster session will also occur two months after the initial training. Both teens and parents will receive a biweekly cumulative driving report.

结局指标
主要结局
Risky Driving Events
时间窗: Six months/study period
Risky driving events are continuously monitored for teens (240) across all three groups using an in-vehicle device and smartphone app. The system automatically detects and records driving events, including hard braking (≤ -0.45 g-force) sudden acceleration (\> 0.35 g-force), speeding (\>10 miles over the posted speed limit), and speed \>75 mph. Event rates are calculated as the number of risky driving events per 1,000 miles driven.
Unsafe Behaviors
时间窗: Six months/study period
Unsafe driving behaviors among teens (N = 240) are continuously monitored across all three study groups using an in-vehicle device and a smartphone app. The system automatically records behaviors such as speeding, and seatbelt nonuse (for selected vehicle makes and model years only), as well as the distance traveled while these behaviors occur. Unsafe behavior rates are calculated as the number of miles involving an unsafe behavior per 1,000 miles driven. Survey data supplement these measures by capturing self-reported distracted driving and seatbelt use for vehicles that are not fully compatible with the in-vehicle device.
次要结局
- Recidivism(Up to one year post-study period)
- Parent-Teen Communication(at baseline, three months, and six months)
