Initial Testing of a Web-Based Intervention to Reduce Adolescent Driver Inattention: A Randomized Controlled Trial

Area of Science:

• Public Health
• Adolescent Medicine
• Traffic Safety

Background:

• Motor vehicle crashes are the primary cause of death for adolescents.
• Driver inattention significantly contributes to crash risk.
• Developing effective interventions to improve adolescent driver attention is crucial.

Purpose of the Study:

• To evaluate the effectiveness of a web-based intervention, "Let's Choose Ourselves," aimed at enhancing adolescent driver attention.
• To assess the intervention's impact on reducing cell phone use while driving, promoting passenger assistance, and minimizing forward roadway inattention.

Main Methods:

• A randomized controlled trial was conducted with 60 adolescent drivers (aged 16-17) with less than 90 days of driving experience.
• Participants were assigned to either the "Let's Choose Ourselves" intervention or an attention control group, with variations in simulator distraction protocols.
• Poisson regression modeling was used to analyze the primary and secondary outcomes at 3-month follow-up.

Main Results:

• The "Let's Choose Ourselves" intervention showed no significant effect on reducing cell phone engagement, increasing passenger management, or decreasing inattention in driving simulations.
• A significant increase in self-reported distracted driving behaviors was observed over time across all groups.
• No significant differences were found in primary or secondary outcomes between the intervention and control groups.

Conclusions:

• The "Let's Choose Ourselves" intervention did not effectively improve adolescent driver attention or reduce risky driving behaviors in the short term.
• Findings suggest that self-reported risky driving behaviors may increase with driving experience, indicating a need for further investigation.
• Future research should explore the complex relationship between driving inexperience and escalating inattention among adolescent drivers.
