projectDRIVE: Intervention to Improve Driving Practices Among High-Risk Teen Drivers
Study Details
Study Description
Brief Summary
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.

Phase 3 |
Detailed Description
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.
Study Design
Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| No Intervention: Control Group The Control Group will have the in-vehicle device installed in the teen's car, but all feedback features will be disabled. |
|
| Experimental: 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. |
Combination Product: In-vehicle device
The Azūga™ in-vehicle driving feedback technology, which consists of a pager-sized device plugged into the vehicle's on-board diagnostic port (installed in the teen's car) and a smartphone app (downloaded on the teen's smartphone), will be installed/downloaded. Three types of feedback will be provided to intervention teens: 1) Direct audio feedback from the installed device; 2) Detailed cumulative driving data; and 3) A customized biweekly driving summary report.

| Experimental: 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. |

Behavioral: Parent Communication
An individualized virtual training in communication strategies about driving safety along with a booster session will be delivered by a traffic safety communication specialist to subjects in the Feedback and Parent Communication Group. Intervention parents in this group will also be provided with access to an online parent-teen safe driving communication guide.

Outcome Measures
Primary Outcome Measures
- Number of Risky Driving Events [Six months/study period]
Events of hard braking and sudden acceleration.
- Number of Unsafe Driving Behaviors [Six months/study period]
Events of speeding, distracted driving, and no seatbelt use.
- Frequency of Parent-teen Communication [Six months/study period]
Frequency of parent-teen communication about driving safety. This will be measured through a survey asking parents how often they discussed a driving topic with their teen.
- Recidivism [Up to one year post-study period]
Recidivism will be measured among teens in all three groups by linking traffic citations and court disposition data with the participating teen's driver's license number. Recidivism during the 12 months following enrollment, including date and type of violation, and days from index violation to subsequent violation will be analyzed.
- Quality of Parent-teen Communication [Six months/study period]
The quality of parent-teen communication about driving safety will be measured through an average rating of each driving topic which is recorded by the parent and teen.
Other Outcome Measures
- Engagement with Parent Communication Training [Six months/study period]
Engagement with the parent communication training will be measured among parents in the Feedback and Parent Communication Group using online measurements.
- Engagement with Device Feedback [Six months/study period]
Engagement with device feedback will be measured among teens in the Feedback Only Group and the Feedback and Parent Communication Group and parents in the Feedback and Parent Communication Group via online tracking of the participant's web interface using Google Analytics.
