What this trial studies

This study will randomly assign 208 individuals with co-occurring substance use and mental health disorders to receive either a comprehensive multi-component treatment approach called MISSION or linkage with a Peer Specialist. The goal is to evaluate which method is more effective in enhancing treatment engagement and improving outcomes related to substance use and mental health. The study will also include a process evaluation to inform future implementation and sustainability of these interventions. Conducted over three years, this research addresses a critical public health issue in Worcester, Massachusetts, where substance use disorders and mental health issues are prevalent.

Not a fit: Patients who are acutely psychotic, suicidal, or have severe alcohol use disorder requiring detoxification may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could significantly improve treatment engagement and recovery outcomes for individuals with co-occurring disorders.

How similar studies have performed: Other studies have shown promise with similar multi-component approaches, but this specific intervention is novel in its application to the Worcester area.
