title: Archival Version

description: This study expands on the Behavioral Intervention to improve adherence to Medication for Opioid Use Disorder (MOUD) among low-income, marginalized individuals in Baltimore, Maryland. Based on Behavioral Activation principles, the "Peer Activate" intervention is specifically designed for implementation by trained peer recovery specialists. 
Implementation outcomes included feasibility, acceptability, and fidelity. Feasibility, defined as the suitability and practicality of the approach, was quantitatively measured by the percentage of participants agreeing to participate in the intervention. Acceptability, defined as satisfaction with or tolerability of the approach, was measured quantitatively by session attendance. Fidelity was evaluated through independent ratings of a randomly selected 20% of sessions. The primary effectiveness measure was methadone retention at three months post-intervention, with secondary outcomes including methadone adherence, substance use frequency, and related problems.
description: The purpose of this study is to examine the feasibility, acceptability, fidelity, and preliminary effectiveness of the Peer Activate intervention on methadone treatment retention over three months.
description: The study follows respondents over the course of three months. Every week respondents were asked questions about their background, substance use, and health. About every week the respondent would meet with a "peer", or someone that is there to help with respondents with their goals, to help give advice and support.
description: These datasets contain variables about various drug use and dosage, methadone treatment adherence, peer roles and their interactions with respondents, activity logs, and interpersonal reflections.
description: Response Rates: Thirty-seven individuals were enrolled in the open-label trial (intent-to-treat sample), with the goal of reaching a minimum of 30 Peer Activate initiators (i.e., defined as completing more than or equal to 1 Peer Activate session). Of the 37 intent-to-treat sample, 32 participants completed at least one Peer Activate session and were defined as the "treatment initiator "group. Thirty-two individuals initiated the Peer Activate intervention, with the goal of reaching a minimum of 24 completers (i.e., defined as completing more than or equal to four Peer Activate sessions). Of the 32 "treatment initiators" group, 26 participants completed at least four Peer Activate sessions and were defined as the "treatment completer" group. Twenty-six participants completed the post-treatment assessment. This includes three people who completed the post-treatment assessment prior to the 4th session and excludes three people who completed 4 Peer Activate sessions but did not complete a post-treatment assessment.
description: N=37 participants were consented and determined to be eligible upon completion of the baseline assessment. Recruitment took place at a community-based opioid treatment program (OTP) in Maryland between October 2020 and August 2021.
