Sustentando a recuperação para pessoas em tratamento com agonistas opioides com agentes conversacionais (SARA RCT)

Participants randomized into the intervention arm will be engaged in ECA use, technical support, additional ECA messages reminding the use of the ECA app on behalf of OBAT clinical staff, and monetary incentives.

The app with the ECA will be provided.

Technical support will include assistance downloading and setting up the app on the participant's phone, walking them through a brief demonstration, and answering any questions the participant has about how to use the app.

Weekly text messages will be provided reminding participants to use the app on behalf of OBAT clinical staff.

Additional incentives will be provided after logging into the app for 20 days followed by monthly lotteries for those who log in 15 days per month

Participants randomized into this arm will receive treatment as usual

Engaged in buprenorphine treatment or treatment retention is defined as a participant's treatment period of at least 365 days, including those with multiple disengagement and reengagement periods, as long as any gap in active prescriptions or receipt of injections is less than 60 days.

Treatment retention is defined as a participant's treatment period of at least 365 days, including those with multiple disengagement and reengagement periods, as long as any gap in active prescriptions or receipt of injections is less than 60 days.

Treatment duration is defined as length of continuous buprenorphine treatment in days until first discontinuation and will be measured via electronic health record (EHR) prescription and injection data and supplemented with self-report. Discontinued buprenorphine treatment occurs once the EHR indicates that they haven't filled a buprenorphine prescription or haven't received a buprenorphine injection in the previous 60 days. The treatment discontinuation date will be the last day of an active prescription or injection received.

Opioid use will be measured by self-report via the modified Addiction Severity Index (ASI). The modified ASI is administered by the study staff for a list of 20 drugs/substances. For each the number of days of use and the route of administration of that drug/substance [0=N/A, 1=oral, 2=nasal, 3=smoking, 4=non-intravenous (IV), injection 5=IV, or 8=refused] is documented.

The SU-SMS is a self reported, 18-item instrument. Each item has a 5 Likert frequency responses from 1=Never to 5=Very often. Total scores can range from 1 to 90 or from 1-30 for each of the three types of stigma [anticipated, enacted, and internalized]. Lower scores are correlated with less stigma.

BT-SMS is a self reported, 25-item instrument. Each item has a 5 Likert frequency responses from 1=Never to 5=Very often. Total scores can range from 1 to 125 or from 1-45 for anticipated stigma, 1-45 for enacted stigma, and 1-35 for internalized stigma. Lower scores are correlated with less stigma.

Changes in recovery capital will be measured by self-report via the Brief Assessment of Recovery Capital (BARC-10) which is a 10-item self administered instrument. Each item has 6 Likert possible responses where 1=Strongly disagree to 6=Strongly agree. Total scores can range from 1 to 60. Higher scores are correlated with more recovery capital.

Frequency of interactions with the ECA app will be collected via the app itself and provided to the BMC study team by the investigators at Northeastern University.

User attitudes and satisfaction with the ECA app will be measured by self-report using the Bond subscale of the Working Alliance Inventory which is an investigator developed instrument. The Bond subscale has 6 questions with an analog type response from 'disagree completely' to 'agree completely'.
