Examine the preliminary effect of the MPACT intervention on methadone treatment retention, in treatment overdose and patient trauma symptoms. The study will also explore the relationship between staff trauma symptoms and MPACT implementation.

Specific AIMS:

AIM 1: Develop MPACT through multilevel, iterative planning with OTP staff and people with recent MMT experience.

AIM 2: Conduct a 4-month MPACT pilot test in two AZ OTPs: Mesa (urban) with 50 patients and 22 staff, and Sierra Vista (rural-serving) with 50 patients and 8 staff to:

1. Determine MPACT implementation feasibility, acceptability, and preliminary effect on MMT practice change and culture.
2. Determine MPACT preliminary effect on MMT retention, in-MMT overdose, and patient PTSS.
3. Characterize staff trauma history, PTSS and vicarious trauma, and explore their relationship with MPACT acceptability and implementation fidelity.

AIM 3: Characterize MPACT acceptability, likely adoption, and recruitment feasibility among directors, case managers and counselors from a national random sample of 500 OTPs.

Inclusion Criteria:

• Staff of enrolled opioid treatment programs (methadone clinics) who are involved with methadone treatment
• Patients receiving methadone at these locations

Exclusion Criteria:

• Patients not receiving methadone at these locations
• Staff not involved in methadone treatment at these locations
