Participants will complete the computerized screening and brief intervention protocol at the time of a primary care office visit.

In the cASBI protocol participants complete a computerized screen for alcohol and drug use, view their screen results on the computer, then see 10 pages of science and true life stories describing the health effects of alcohol and other substance use. The provider receives a report of the screen results and gives brief advice regarding alcohol and drug use during the office visit. The cMET protocol is a 2 session intervention composed of 8 exercises designed to encourage adolescents their alcohol and other substance use and develop a plan to stop or reduce their use.

The investigators will measure the percentages of completed cMET sessions by those referred to cMET.

The investigators will measure patient satisfaction with the cMET program.

The investigators will measure rates of any alcohol use, days of alcohol use, drinks per drinking day, and days of heavy episodic drinking in the cASBI+cMET group vs the cASBI group.
