AbstractBackgroundMindfulness‐based interventions have a positive impact on pain, craving, and well‐being in both patients with chronic pain and those with opioid use disorder (OUD). Although data are limited, mindfulness‐based cognitive therapy (MBCT) might be a promising treatment for patients with chronic noncancer pain combined with OUD. The aim of this qualitative study was to explore the feasibility and process of change during MBCT in this particular population.MethodsIn this qualitative pilot study, 21 patients who were hospitalized for rotation to buprenorphine/naloxone as agonist treatment for chronic pain and OUD were offered MBCT. Semistructured interviews were conducted to explore experienced barriers and facilitators to MBCT. Patients who participated in MBCT were also interviewed on their perceived process of change.ResultsOf 21 patients invited to participate in MBCT, 12 initially expressed interest but only four eventually participated in MBCT. The timing of the intervention, group format, somatic complaints, and practical difficulties were identified as the main barriers to participation. Facilitating factors included having a positive attribution toward MBCT, an intrinsic motivation to change, and practical support. The four MBCT participants mentioned several important mechanisms of change, including reduction of opioid craving and improved coping with pain.ConclusionsMBCT offered in the current study was not feasible for the majority of patients with pain and OUD. Changing the timing of MBCT by providing it at an earlier stage of the treatment and offering MBCT in an online format may facilitate participation.
