Brief Summary

Steering Teens Safe (STS) is an evidence-based and parent-focused intervention developed by the investigators, which aims to improve safe teen driving practices by enhancing parental communication skills. The objective of this translation study is to assess the effect of STS on driving outcomes among teen drivers who have committed a traffic violation, and to assess the adoption and implementation fidelity of STS in a county court setting and among these high-risk teen drivers and their parents. The investigators will test the following specific aims: Aim 1: Determine the effects of the intervention on parent-teen communications and risky driving outcomes (risky driving events, unsafe driving behaviors, and recidivism) among teen drivers with a traffic violation(s). Aim 2: Assess the adoption of the intervention and implementation fidelity We will enroll 90 parent-teen dyads, comprised a teen driver (16 to 17 years) who committed a moving violation and a parent/legal guardian, from the Ohio Franklin County Juvenile Traffic Court following the teens' mandatory court hearing. Enrolled dyads will be randomly assigned to 1 of 2 study groups (n=45/group): 1) Control, device installation only with no feedback to nor communication training for parents, or 2) Intervention, device feedback to teens and parents, and parents will also receive individualized virtual communication training. The expected outcome is to establish the effectiveness of STS augmented with driving feedback technology, and to establish the implementation fidelity of STS in a court setting.

Outcome Measures

Primary Outcomes (6)

• Frequency of Parent-teen communications

  Frequency of parent-teen communication about driving safety. This will be measured through a survey asking parents how often they discussed the topic with their teen on driving topics.

  Six months/study period

• Number of Risky driving events and unsafe behavior rates

  Events of hard braking, sudden acceleration, speeding, distracted driving, and no seatbelt use.

  Six months/study period

• Recidivism

  Recidivism will be measured among teens in both 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

  Up to one year post-study period

• Adoption of the intervention

  Adoption of the intervention by using publicly available court data from Franklin County Juvenile Traffic Court and compare it to all other juvenile traffic courts in Ohio. We will also use participant characteristic data and compare it to non-participating teens with a moving violation in Ohio.

  Six months/study period

• Implementation fidelity

  Engagement with community training via a self-report questionnaire, engagement with device feedback via Google Analytics, and a fidelity checklist will be combined to report implementation fidelity

  Six months/study period

• Quality of Parent-teen communication

  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.

  Six months/study period

Study Arms (2)

Control Group

NO INTERVENTION

The Azūga™ in-vehicle driving feedback technology will be installed.32 This driving feedback technology consists of a pager-sized device plugged into the vehicle's on-board diagnostic (OBD) port (installed in the teen's car) and a smartphone app (downloaded on the teen's smartphone). All feedback features will be disabled. Control dyads will receive no driving feedback. The parent will not receive STS. Additionally, a wireless mini-camera will be installed on the dashboard in teen's car to identify the participating driver using facial verification technology.

Intervention Group

EXPERIMENTAL

Parents will receive STS, which will include 1) Individualized virtual communication training and a booster session delivered by a traffic safety communication specialist; and 2) An online parent-teen safe driving communication guide. In addition, the Azūga™ in-vehicle device and app will be installed as described above and all feedback features will be enabled. Three types of feedback will be provided to teens: 1) Direct audio feedback; 2) Detailed cumulative driving data; and 3) A customized weekly driving summary report. Parents in this group will receive access to the teen's cumulative driving data and a weekly driving summary report. Additionally, a wireless mini-camera will be installed on the dashboard in teen's car to identify the participating driver using facial verification technology.

Interventions

Steering Teens Safe (STS) BEHAVIORAL

The goal of STS is to provide intervention parents with guidance and communication skills, which will enable parents to effectively communicate with their teens about specific driving safety topics (e.g., speeding, seatbelt use, distracted driving). Our proposed parent training has two components: an individualized virtual communication training (provided to parents via Skype by a trained research team member) and a parent-teen safe driving communication guide (available online).

Also known as: STS

Intervention Group

Driving Feedback Technology. BEHAVIORAL

The driving feedback technology will include the Azūga™ in-vehicle device and smartphone app.

Also known as: Azuga device

Model Details: We propose a hybrid, RCT to test the effectiveness and implementation of an evidence-based, parent-focused intervention among teen drivers with a moving violation. We aim to recruit 90 dyads (45 per group, totaling 180 study participants), comprised of one teen driver ages 16 or 17 who has committed a moving violation (e.g., speeding, failure to obey traffic signal) and the parent/legal guardian ('parent') who is most involved with the teen's driving. Recruitment will occur at the Franklin County Juvenile Traffic Court in Ohio following the parent-teen dyad's mandatory court appearance. After completing informed consent/assent and the baseline assessment, enrolled parent-teen dyads will be randomly assigned into either the Control or Intervention Group using a stratified block randomization. All enrolled dyads will be followed for a 6-month period.
