Summary

This study is testing a web-based tool called ChangeGradients that uses machine learning to create personalized stories for teens who drink alcohol. The goal is to help them understand the risks and make healthier choices. Researchers are recruiting 200 adolescents aged 15-17 who currently drink and are coming in for a check-up at UCSF clinics. The tool will be used during the visit, and teens will be asked about their drinking and confidence to avoid alcohol in different situations.

What this could mean

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

Active substance
ChangeGradients web-based behavioral tool
What this could lead to
If it works, this could point toward a scalable, personalized way to help teens reduce risky drinking during routine clinic visits.
What could go wrong
This is an early-stage study testing a new approach, not a proven treatment. The tool may not change behavior more than standard advice, and results may not apply to all teens.
