Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Motor vehicle collisions (MVCs) are the leading cause of death among teenagers in the United States. Teen drivers who have committed a traffic violation are at an even greater risk for MVCs than their counterparts. While parent-focused interventions are an effective strategy to improve teen driving safety, most of these interventions target teen drivers are implemented as universal interventions (for teens of all risk profiles). Evidence on the effectiveness of these evidence-based interventions when translated and implemented among high-risk teen drivers such as those with a traffic citation is lacking.

The current project is significant because it will translate the STS program to the needs of high-risk teen drivers who have committed a traffic violation and their parents. This study is innovative because it partners with the local court system, and utilizes novel and cutting-edge in-vehicle technology. The findings of the current study will have a significant impact on juvenile traffic court's practices and policies aimed to improve teen driving safety by reducing MVC-related crashes, injuries, and deaths.

Study Design

Understand how the trial is structured, including allocation methods, masking strategies, primary purpose, and other design elements.

Allocation Method

RANDOMIZED

Intervention Model

PARALLEL

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.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Control Group

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.

Group Type NO_INTERVENTION

No interventions assigned to this group

Intervention Group

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.

Group Type EXPERIMENTAL

Steering Teens Safe (STS)

Intervention Type 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).

Driving Feedback Technology.

Intervention Type BEHAVIORAL

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