What is the purpose of this trial?

This trial tests two support methods for individuals with both substance use and mental health issues. One group receives Full MISSION, which involves a comprehensive team approach with mental health and substance use treatment. The other group receives assistance from a Peer Specialist who connects them to community services. The researchers aim to determine which method better improves treatment engagement and overall health outcomes. Individuals with both substance use and mental health disorders, who are part of the Worcester Hub and have not participated in similar treatment for at least three months, might be suitable for this trial. As an unphased trial, this study offers a unique opportunity to contribute to innovative approaches in mental health and substance use support.

Will I have to stop taking my current medications?

The trial information does not specify if you need to stop taking your current medications. It might be best to discuss this with the trial coordinators.

What prior data suggests that these interventions are safe for individuals with co-occurring disorders?

Research has shown that the MISSION model is a proven program designed to assist individuals with both mental health and substance use issues. It integrates treatments for these conditions with support services. Studies have found that combining different types of support can be highly effective for individuals facing both challenges. The program has been implemented in various settings, including for veterans, and emphasizes helping individuals achieve independence and sobriety.

Regarding safety, strong scientific support exists for using combined mental health and case management services. This approach is generally well-received and has been safely applied to diverse groups. No specific reports of negative effects related to the MISSION model appear in the sources provided, suggesting the program is safe for participants. ^{1 2 3 4 5}

Why are researchers excited about this trial?

Researchers are excited about the trial comparing Full MISSION services and Linkage Only support because it explores innovative ways to treat dual diagnosis, which involves both mental health and substance use disorders. Unlike standard treatments that might tackle each condition separately, the Full MISSION approach integrates mental health and substance use treatment over six months. This includes structured sessions with both a case manager and a peer support specialist, using a comprehensive treatment manual and workbooks. On the other hand, the Linkage Only approach focuses on connecting participants with community services through a peer specialist, emphasizing informal support without integrated treatment. This trial could uncover more effective strategies for providing holistic and accessible care for those with dual diagnoses.

What evidence suggests that this trial's treatments could be effective for co-occurring substance use and mental health disorders?

Research has shown that the MISSION program, available to participants in this trial, effectively addresses mental health and substance use issues. Past studies found that individuals who participated in MISSION engaged more in treatment and experienced improved mental health. These benefits appeared in settings like veteran services, where similar needs exist. The program provides comprehensive support through therapy, peer assistance, and connections to community resources, which are believed to enhance independence and sobriety. In contrast, the peer support component of the program, another treatment option in this trial, offers basic assistance without therapy, making it less comprehensive than the full MISSION model. This suggests that while peer support is beneficial, the full MISSION approach may lead to greater improvements. ^{1 3 6 7 8}

What Are the Treatments Tested in This Trial?

Interventions

• Full MISSION
• Linkage Only Delivered by a Peer Specialist

Trial Overview

The study compares MISSION (a comprehensive team-based approach) to just getting linked up by a Peer Specialist for people with substance and mental health issues. The goal is to see which method better improves treatment engagement and health outcomes.

How Is the Trial Designed?

Group I: Full MISSION Experimental Treatment 1 Intervention

Participants assigned to this condition will receive full MISSION services. MISSION services include 6-months of integrated mental health and substance use treatment and treatment planning with the MISSION Case Manager (13 session curriculum) and Peer Support Specialist (11 session curriculum). Content of these sessions will be directed using the MISSION Treatment Manual and Consumer Workbooks. MISSION teams will also provide linkages and supports to treatment services within the participant's community throughout the duration of the study.

Group II: Linkage Only Delivered by a Peer Specialist Active Control 1 Intervention

Our Linkage only arm delivered by a Peer Specialist will act as the comparison group to the MISSION arm. Participants randomized to the linkage only arm will receive 6-months of linkage care from a Peer Specialist. The Peer Specialist will provide informal treatment planning as well as linkages and support to community services, but will not provide integrated dual disorders treatment, nor will this arm utilize any MISSION materials or offer Peer led groups.

Full MISSION is already approved in United States for the following indications:

Approved in United States as MISSION Program for:
