Trial of Computerized SBI to Reduce Teen Alcohol Use

Study Overview
=================
Brief Summary
-----------------
The goal of this project is to test the effectiveness of a computer-facilitated alcohol screening and brief intervention (c-ASBI) system for 12- to 18-year-old primary care patients in a multi-site, randomized comparative effectiveness trial. The investigators hypothesize that, among 12- to 18-year olds patients coming for annual well-care, those receiving c-ASBI will have lower rates of any alcohol use at 3-, 6-, and 12-month follow-ups compared to Treatment As Usual (TAU).

Detailed Description
-----------------
The Specific Aims are to 1) Test the effects of c-ASBI on any alcohol use; 2) Test the effects of c-ASBI separately as a prevention, therapeutic, and risk-reduction intervention; 3) Test the effects of c-ASBI separately on cannabis and tobacco use; explore its effects on other drug use; and 4) Assess potential moderators (e.g., age, gender, race/ethnicity, substance use history +/-, parent/sibling/peer substance use), mediators (e.g., Youth to Provider Connectedness,20 perceived harmfulness of alcohol and drug use), and explore c-ASBI's mechanism of action.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| No Intervention: Treatment at Usual<br>Participants in this group will receive treatment as usual (TAU) from their provider, which may or may not include screening and brief advice regarding alcohol use. | |
| Experimental: c-ASBI<br>Participants in this group will receive the computerized alcohol screening and brief intervention (c-ASBI). | Behavioral: c-ASBI<br>* Participants in the c-ASBI group will complete a computerized screen for alcohol, cannabis, tobacco and other drugs, then view their screen score and 10 pages of information about the health effects of substance use and true-life stories on the computer. Their provider will see a report of their screen results and provide advice to stop or decrease their use, or, for those at high risk, referral to complete a computerized motivational enhancement therapy intervention.<br>|
