Social Networks and Methadone Maintenance Treatment Retention and Antiretroviral Therapy Retention in Tanzania

Investigators will adapt the Brief Social Behaviour and Network Therapy (B-SBNT) intervention developed to facilitate recovery among people receiving medication-assisted treatment for opioid use disorder in the United Kingdom. The B-SBNT involves families and the wider social networks of people receiving medications for opioid use disorder to support recovery. Key components of the intervention include: mapping the social networks of clients; inviting others identified through the mapping to participate in the intervention; building communication strategies with network members; and developing joint activities with network members. In the original B-SBNT, the intervention is delivered by therapists/clinicians who undergo training. Investigators will pilot test the adapted version of this intervention with a maximum of 80 people: 20 current clients receiving methadone maintenance treatment (MMT) at the Muhimbili National Hospital (MNH) Medically-Assisted Treatment (MAT) Clinic and up to 60 social support persons identified by recruited MMT clients. The pilot will assess the social network intervention's acceptability and feasibility.
