Computer Adaptation of Screening, Brief MET Intervention to Reduce Teen Drinking

Study Overview
=================
Brief Summary
-----------------
The goal of this project is to evaluate the feasibility, acceptability, and effect size of a new computerized Motivational Enhancement Therapy (cMET) intervention for alcohol-involved adolescents in primary care.

Detailed Description
-----------------
The study aims are to: Assess cMET feasibility and acceptability and estimate its effect size on underage drinking. Hypothesis: Among 14- to 20-yr-old primary care patients, those receiving cMET will have lower rates of any alcohol use, days of alcohol use, drinks per drinking day, and days of heavy episodic drinking, than those receiving treatment as usual. Estimate effect sizes for tobacco, cannabis, and other drug use, and other substance-related risks and outcomes including substance-related driving/riding, and experience of substance-related problems. Identify potential moderators and mediators of cMET's effect.

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| No Intervention: Treatment As Usual<br>Those randomized to Treatment as Usual (TAU) will not complete cMET but will receive standard treatment from the doctor. | |
| Experimental: cMET<br>Those randomized to cMET will complete a 2-session computerized Motivational Enhancement Therapy (cMET) intervention. | Behavioral: cMET<br>* Those in cMET complete the 2-session self-administered computerized intervention which includes 8 exercises designed to encourage adolescents to evaluate the impact of alcohol and other substance use on their health and well-being and consider changing their use.<br>* Other names: Computerized Motivational Enhancement Therapy intervention;|
