Overview
Brief Summary
To translate our evidence-based, parent-engagement safe teen driving intervention to a high-risk, rural and urban teen drivers with a traffic violation, and to test the implementation, effectiveness, and cost-effectiveness of the proposed intervention.
Detailed Description
For this study, 290 teen and parent/guardian dyads will be randomized into one of three study groups for 12 months with 6 months of active data collection. 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. Dyads will be recruited from both urban and rural counties in Ohio following the teen's moving violation conviction. The study will determine the effectiveness and cost-effectiveness of the intervention on teens' risky driving events, unsafe driving behaviors, traffic violation recidivism, and motor vehicle collisions (MVCs), as well as frequency and quality of parent-teen communications about safe driving practices. Additionally, the study will determine the effectiveness and cost-effectiveness of the peer-delivered intervention vs. expert-delivered intervention on the outcomes of the interest. Finally, the study will assess the barriers/facilitators to the adoption and implementation of the intervention in rural and urban families.

Outcomes
Primary Outcomes
Unsafe driving behaviors
Time Frame: Daily overtime for six months following enrollment
Using the Azūga™ in-vehicle device and smart phone app, the investigators will collect data in both intervention groups and the control group on teen's unsafe driving behaviors (speeding, distracted driving, no seatbelt use). The duration (e.g., miles driven) and type of driving behaviors, including speeding (\>10 miles over the posted speed limit), and no seatbelt use, will be automatically coded and counted in the system. The proportions will be calculated by dividing by miles driven then multiplying by 1000 (e.g., proportion of 1,000 miles in which a seatbelt was not worn).
Change in Reach
Time Frame: Yearly for 3 years
Reach will be measured by comparing characteristics of teens who enrolled in the study to those who declined participation (e.g., demographics, residence location, citation history). The investigators will assess the number of eligible participants who are offered participation on each recruitment day, the number of those who were offered participation and declined as well as participation and drop-out rates.
Adoption - Courts: 3 Years
Time Frame: 3 years
Adoption will be measured by comparing characteristics of participating county courts (Franklin, Greene, Perry, and Wyandot Juvenile Traffic Courts) to county courts in the rest of Ohio (e.g., court hours, location, the number of staff, the number of cases). The investigators will also conduct interviews with participating court officials to identify facilitators and barriers to program adoption.
Implementation Fidelity - Fidelity Checklist
Time Frame: After completion of each intervention session, up to three years
Implementation fidelity will be measured among the expert and peer trainers immediately after the intervention using a fidelity checklist. The fidelity checklist will measure intervention fidelity including conceptual accuracy and adherence, and responsiveness to the needs of participants. Trained Raters will review a sample of recorded training and booster sessions and complete the fidelity checklist.
Direct Costs: 3 Years
Time Frame: 3 years
Direct costs refer to the personnel and non-personnel costs that can be assigned to the intervention (i.e., STS+). Personnel costs include service time and the proportion of staff time allocated to implement STS+ and non-personnel costs refer to other items needed for delivering STS+, such as equipment, supplies and materials. Examples of direct costs include staff time required to 1) deliver the intervention, 2) train the peer trainers, 3) install, manage, and maintain the driving feedback technology, 4) manage the STS+ website platform, and 5) train participants to use the driving feedback technology and STS+ website platform. Direct cost data will be collected yearly from all dyads using a cost data collection protocol and template that includes annual costs for personnel, technology, training requirements, supplies, and infrastructure.
Risky driving events
Time Frame: Daily overtime for six months following enrollment
Risky driving events (hard braking, sudden acceleration) will be collected among teens in the intervention groups and control group using the Azūga™ in-vehicle device. The number and type of driving event, including hard breaking (≤ -0.45 g-force) and sudden acceleration (\> 0.35 g-force), will be automatically coded and counted in the system. The rates will be computed by dividing events by miles driven then multiplying by 1000.
Adoption - Participants
Time Frame: At 6-month follow-up
The investigators will also conduct interviews with a randomly selected sample of dyads in each intervention group (n=116, 58 dyads for each intervention group) to identify facilitators and barriers to program adoption.
Implementation Fidelity - BECCI
Time Frame: After completion of each intervention session, up to three years
Implementation fidelity will be measured among parents in both intervention groups, and among the expert and peer trainers immediately after the intervention using the Behavior Change Counseling Index (BECCI). The BECCI measures the degree to which the intervention is delivered as intended and involves 11 items rated on a scale of 0 to 4. The average of all items will be calculated, with higher scores representing greater fidelity.
Secondary Outcomes
- Parent-teen communications about driving safety(During 6 months of enrollment)
- Motor Vehicle Collision(At 12 months following enrollment)
- Traffic Violation Recidivism(At 12 months following enrollment)
- Maintenance(At 6-month follow-up)
- Indirect Costs: 3 Years(3 years)
