Brief summary
Screening youth in the primary care setting is one way to identify adolescents who may be at-risk for future alcohol problems. The current study tests the new NIAAA screening guide questions, which ask about friend and adolescent drinking, to see how well these questions work to predict subsequent alcohol use, problems, and involvement in other risk behaviors, such as sexual risk-taking and delinquency. In addition, the investigators plan to provide a brief motivational intervention for some at-risk teens and see whether alcohol use differs for those teens who receive the intervention and those teens who receive enhanced usual care. The results of this study have the potential to significantly impact the standard of care for identifying and intervening with at- risk youth in primary care settings.

Pre-assignment details
this study included an examination of screening; thus, not all youth were part of the randomized controlled trial as they screened in at low risk. This is why there is a larger N for the overall sample. The 294 are the youth that screened in as at-risk who were then part of the RCT.

| CHAT Brief MI Intervention Youth in CHAT will receive screening for alcohol and drug use. Those youth who are at risk will have a chance to talk to their provider about their use. In addition, these youth will CHAT. CHAT is a brief motivational intervention that takes places in the primary care setting. It is a 15-20 minute intervention for adolescents age 12-18 focused on discussing alcohol and drug use. They will also receive a booster call one month later to check in on how they are doing.
