Summary

This completed trial tested a computer-based system (cSBI) that helps pediatricians screen and counsel teens aged 14-17 about alcohol use and driving risks. The system includes a self-administered questionnaire, educational content, and a report for the doctor to guide a brief counseling session. The study enrolled 169 teens across multiple U.S. primary care practices to see if this approach reduces heavy drinking and risky driving behaviors.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
Computer-facilitated screening and brief intervention (cSBI) - a behavioral tool
What this could lead to
If effective, this approach could give pediatricians a practical, scalable way to reduce heavy drinking and risky driving among teens.
What could go wrong
This is a completed trial, but results are not yet widely implemented. The tool's success depends on clinician adoption and may not work in all practice settings.
