Summary

Severe chronic pain and opioid use disorder (OUD) occur at significantly higher rates in Veterans compared to the general population. Chronic pain often persists despite engagement in opioid agonist treatment (OAT), the first line treatment for OUD. Recent VA guidelines strongly recommend non-pharmacologic treatment for chronic pain, but individuals with OUD are frequently excluded from pain treatment studies. There is a need for evidence-based pain treatments that compliment OAT for Veterans with chronic pain and OUD. In this study, the investigators will determine feasibility and acceptability for a behaviorally focused pain treatment that includes pain education and a pedometer assisted adaptive walking program for Veterans receiving OAT for OUD. Potential treatment outcomes will be repeatedly assessed using a mobile device, and study-provided pedometers. By offering pain treatment within OAT clinical care, the investigators hope to decrease stigma and increase access for Veterans with chronic pain and OUD.
