Peer MI for Substance-using Emerging Adults

October 9, 2018 updated by: Douglas Smith, University of Illinois at Urbana-Champaign

Peer-enhanced Motivational Interviewing for Emerging Adults With Risky Substance Use

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.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: 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.
Behavioral: 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.
Other: Waitlist Control
Delayed Treatment.
Other: 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.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
GAIN Substance Problem Scale
Time Frame: Baseline and every 2 weeks during 12 week post-intervention period
a 16-item scale composed of lifetime symptoms of substance abuse, dependence, and substance-induced health and psychological disorders based on the DSM-IV
Baseline and every 2 weeks during 12 week post-intervention period

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
GAIN Substance Frequency Scale (change)
Time Frame: Baseline and every 2 weeks during 12 week post-intervention period
The GAIN substance frequency scale (SFS) measures the percent of days of substance use and percent of days of related problems from such substance use. This scale encompasses a large number of classes of substances, found to be ideal for measurement among poly- substance using individuals.
Baseline and every 2 weeks during 12 week post-intervention period
Rutgers Alcohol Problem Index (change)
Time Frame: Baseline and every 2 weeks during 12 week post-intervention period
a 23-item self-administered screening tool (questionnaire) for assessing adolescent problem drinking. Respondents simply circle the number that corresponds to the number of times they have experienced each problem. Items can also be read aloud by an interviewer to clients with reading difficulties or it can be used as a springboard for a discussion of problems related to the client's alcohol use.
Baseline and every 2 weeks during 12 week post-intervention period
Significant Other Behavior Questionnaire
Time Frame: Baseline and every 2 weeks during 12 week post-intervention period
An instrument measuring the specific social support in terms of the patient's drinking. Assessments of the significant other's behavior in the presence of the patient drinking is provided by both the patient and significant other.
Baseline and every 2 weeks during 12 week post-intervention period
