About this trial
This study aims to improve retention in buprenorphine treatment, a medication used for opioid use disorder, through the use of a smartphone-delivered recovery support intervention. The intervention involves an Embodied Conversational Agent (ECA), a virtual, animated computer agent designed to simulate natural face-to-face conversations. ECAs have been shown to help individuals manage their healthcare in other settings, and this study seeks to evaluate their potential in supporting patients on medication for opioid use disorder (MOUD).

Treatments tested in this trial
Embodied conversational agent (ECA)
Other interventionThe app with the ECA will be provided.
Technical support
Other interventionTechnical 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.
Additional ECA messages
Other interventionWeekly text messages will be provided reminding participants to use the app on behalf of OBAT clinical staff.

Other interventionAdditional 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
Treatment groups
Trial outcomes
Primary outcomes
Number of participants that stay engaged in buprenorphine treatment
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.
Secondary outcomes
Treatment retention at 6 months
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
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
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.
Changes in stigma based on the Substance Use Stigma Mechanism Scale (SU-SMS)
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.
