Brief Summary

The main purpose of this project is to test whether Peer-Enhanced Motivational Interviewing (PMI) results in superior alcohol and marijuana use outcomes for emerging adults (EAs, ages 18-29) and their peers. Ninety peer dyads (total n = 180, ntarget client = 90, npeer = 90) are randomized to receive either Peer-Enhanced Motivational Interviewing (PMI) or Waitlist Control (WC).

Detailed Description

This project randomized peer dyads, consisting of one EA (Emerging Adult; 18-29 years old) with a substance use problem (i.e. target client) and one peer, to one of two conditions. In the Peer-Enhanced Motivational Interviewing (PMI) condition, target clients and peers will receive separate one-hour sessions of Motivational Interviewing (MI) , an empirically-supported treatment that helps individuals work through ambivalence about making changes in substance use. MI is thought to work because it is a non-confrontational intervention where a therapist empathetically reviews substance use behaviors, listens empathetically, and reinforces any client statements indicating a desire to change. With the 'peer' of each PMI dyad, the therapist presents peers with data about the extent of the target client's substance use, builds the peer's motivation to help their friend, and teaches the peer communication skills they can use to influence the target client's substance use. In the WC condition, target clients and peers can receive PMI after the study follow-up period. Both target clients and their peers are followed for 12 weeks post-intervention.

Study Groups

Peer-Enhanced Motivational Interviewing

Both dyad members, the target client and their peer support person, in this Peer-Enhanced Motivational Interviewing arm will receive separate one-hour Motivational Interviewing (MI) sessions with a trained counselor.

Group Type: EXPERIMENTAL

Peer-Enhanced Motivational Interviewing

Intervention Type: BEHAVIORAL

Target clients in this Peer-Enhanced Motivational Interviewing arm will receive separate one-hour Motivational Interviewing (MI) sessions, in which the therapist reviews the target clients substance use behaviors in a non-confrontational manner, listens empathetically, and reinforces any client statements indicating a desire the change. In this arm, the therapist also presents the target client's peer with data about the extent of the target client's substance use, builds the peer's motivation to help their friend, and teaches the peer communication sills they can use to influence the target client's substance use behaviors.

Waitlist Control

Delayed Treatment.

Group Type: OTHER

Waitlist Control

Intervention Type: OTHER

After the 12 week follow up period, if subjects in the Waitlist Control group desire to receive the Peer-Enhanced Motivational Interviewing intervention, that will be made available to them.
