Opioid use disorder is a chronic, relapsing disease and a major source of morbidity and mortality in the United States. Medication Assisted Treatment (MAT) has been shown to reduce opioid use in diverse populations; however, long-term retention in MAT care is often suboptimal. Depression, the stigma of opioid use and addiction, and limited self-efficacy to navigate life challenges have been shown to contribute to MAT disengagement. Behavioral activation (BA) therapy is an evidenced-based, behavioral treatment that has been shown to be effective in treating comorbid depression and substance use in diverse populations with smoking, alcohol, stimulant, and poly-substance use disorder. Conceptual Model. The conceptual model underlying BA posits that self-defeating behaviors, such as substance use and the behavioral avoidance of health-promoting resources serve the function of coping with negative feelings and make individuals feel better in the short-run, but ultimately exacerbate depression through a process of negative reinforcement. BA utilizes therapeutic techniques that help patients gradually increase goal-directed, potentially rewarding and pleasurable activities while decreasing the intensity and frequency of adverse events and consequences in order to improve mood. Given that BA utilizes strategies that can support individuals in alleviating depression, cope with stigma, and build the capacity to navigate life challenges, pairing BA with MAT could help to ensure continued engagement in care and improve treatment outcomes for individuals with opioid use disorder. Overview of Study. Following the NIH Stage Model of psychosocial treatment development and testing, this study seeks to determine the feasibility of study procedures, enhance participant acceptability, and provide preliminary efficacy data to support the submission of a full-scale, NIH R01 efficacy trial. We will enroll 80 individuals currently being treated with MAT for opioid use disorder in a pilot randomized controlled trial (RCT) of the CoMBAT (Combined Medication and Behavioral Activation Treatment) intervention. Prior to randomization, participants will receive 2 health navigation and standard substance abuse counseling sessions. Participants will then be equally randomized to either: 1) the 6-session CoMBAT intervention; or 2) MAT alone (treatmentas- usual). The primary outcome is retention in MAT care. Secondary outcomes include days of opioid use, opioid positive urinalysis, and potential mediators (e.g., depression, stigma coping, self-efficacy) and moderators (e.g., comorbid mental health, substance use, criminal justice system involvement) of the intervention at baseline, and 3- and 6-months. Intervention feasibility and acceptability will also be assessed. This study will provide the requisite data to inform future efficacy testing of the intervention in a large-scale R01 trial, with the ultimate goal of developing an efficacious intervention to address the opioid epidemic.
