Interventions and Outcome Measures

Arms

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.

other: Waitlist Control

Delayed Treatment.

Interventions

Peer-Enhanced Motivational Interviewing

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

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.

Primary outcome measure

  • GAIN Substance Problem Scale [ Time Frame: Baseline and every 2 weeks during 12 week post-intervention period ]
