Peer MI in FQHCs for Substance-using Emerging Adults

Summary

The main purpose of this study is to test whether a Peer-Enhanced Motivational Interviewing (PMI) intervention, which has been successful with college students, results in superior alcohol and marijuana use outcomes for emerging adults (EA), ages 18-29, who are clients of Federally-qualified Health Centers, and their peers. In the first phase of the study, seventy-five peer dyads (total n = 150, ntarget client = 75, npeer = 75) will be randomized to receive either Peer-Enhanced Motivational Interviewing (PMI), Motivational Interviewing only (MI) or Waitlist Control (WC.) In the second, expanded phase of the study, an additional 325 peer dyads (total n = 650, ntarget client = 325, npeer = 325) will be randomized to receive either Peer-Enhanced Motivational Interviewing, Motivational Interviewing only (MI) or Waitlist Control.

Interventions

BEHAVIORAL

Peer-enhanced Motivational Interviewing

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 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 skills they can use to influence the target client's substance use.

BEHAVIORAL

Motivational Interviewing

In the Motivational Interviewing (PMI) condition, target clients only will receive 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.

OTHER

Waitlist Control

Dyads randomized to this intervention will have no contact with study personnel until 2 months after the PMI group has completed the PMI intervention. Then those in the Waitlist Control condition will receive the full PMI protocol.
