NCT ID NCT05988931
First seen Jun 26, 2026 · Last updated Aug 28, 2026 · Updated 2 times
Summary
This study tests two digital programs to prevent or reduce alcohol misuse in teens aged 12-19 who have used alcohol in the past year. Participants receive a brief web program, and some also get 8 weeks of supportive text messages. Parents are encouraged to use a free app to guide conversations. The goal is to see if these scalable tools can lower drinking and related problems.
