About this study
Official title: Reducing Opioid and Other Drug Use in Justice-Involved Emerging Adults Using Paraprofessional Coaches (With and Without Lived Experience) to Deliver Effective Services in a Non-Treatment Setting
The overarching purpose of this pilot study is to investigate an increasingly common, but under-researched, practice of employing paraprofessional coaches to improve emerging adults' access to and engagement in evidence-based substance use practices, focusing on the paraprofessional coaches' outcomes and the role of lived experience.
Read the detailed description
Criminal legal system involved emerging adults are one of the highest-risk populations for opioid and other substance use and other significant problems (criminal behaviors), but they lack access to and engagement in evidence-based practices. The deleterious outcomes and long-term costs of substance use for emerging adults, communities, and society (estimated at over $740 billion annually and greater than costs for any other health problem), make this a priority. This pilot project is aimed at using paraprofessional coaches to increase engagement and access to evidence-based practices (i.e., contingency management for substance use and vocational/educational coaching) for emerging adults with substance use and criminal legal system involvement. In partnership with parole and probation, sixty emerging adults with substance use will be randomized to work with twenty paraprofessional coaches either with or without lived experience (i.e., successful substance use recovery and/or adult criminal legal system involvement). Although using peer paraprofessional coaches (those with lived experience) is becoming more popular and supported at the federal level, the outcome of this work on the paraprofessional coaches themselves, especially for emerging adults, is largely unexplored. The proposed study will use both quantitative and qualitative methods to assess feasibility and acceptability of the services and research protocols and to gain a better understanding of the impacts on both the coaches and their emerging adult clients. As substance use and poor vocational/educational attainment greatly increases the likelihood of recidivism, innovative strategies to reduce opioid and other substance use for emerging adults is critical, along with understanding the effects on the service providers (i.e., paraprofessional coaches). Aim 1: Determine the feasibility of paraprofessional coaches to deliver (with high adherence) the established interventions to emerging adults with substance use and criminal legal system involvement as part of probation and parole services, and explore differences in the delivery of the interventions based on lived experience. Aim 2: Compare emerging adult clients' engagement (attendance, completion of the intervention) and outcomes (substance use, vocational/educational attainment, criminal recidivism), when interventions are delivered by paraprofessional coaches with vs. without lived experience. Aim 3: For paraprofessional coaches delivering the interventions, examine the differences over time between those with vs. without lived experience on their own substance use symptoms and substance use relapse risk factors.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Contingency Management (CM) combined with vocational/educational coachingBehavioural
Two evidence based practices, CM and vocational/educational coaching, will be combined and delivered by paraprofessional coaches in an intervention named PEERS (Peers Education Empowering Recovery Supports). CM uses positive reinforcement (e.g., chances to win prizes) for clients who abstain from substance use. A standardized and well-validated CM protocol will be used in the proposed study. Vocational/educational coaching assists individuals in completing educational and vocational goals. A workbook developed specifically for vocational/educational coaching in emerging adults will be used in the study.

What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Changes from baseline up to 30 months post-baseline in Paraprofessional Coach Urine Drug Screens (measured at 0, 6, 12, 18, 24, and 30 months). (time frame: Baseline to 30 months). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 6 Feb 2026.
