Villarreal, Y. R., Stotts, A. L., Paniagua, S. M., Rosen, K., Eckmann, M., Suchting, R., & Potter, J. S. (2020). Mindfulness predicts current risk of opioid analgesic misuse in chronic low back pain patients receiving opioid therapy. Journal of Contextual Behavioral Science, 18, 111-116. doi:10.1016/j.jcbs.2020.08.011
Background
Acceptance and mindfulness processes indicating psychological flexibility may be important mechanisms in chronic pain adaptation; however, their association with opioid analgesic misuse (OA) risk is unclear. The present study investigated the extent to which psychological flexibility is associated with OA misuse risk within a chronic low back pain population on long-term opioid therapy.
Methods
Participants were 156 patients presenting for treatment at an academic pain clinic. Aspects of psychological flexibility were assessed using the Mindfulness Attention Awareness Scale (MAAS) and the Acceptance and Action Questionnaire II (AAQ II). The Current Opioid Misuse Measure (COMM) determined heightened risk of opioid analgesic misuse. Participants were 59% female, 48.3 years old on average (SD = 9.8), and largely White, Hispanic.
Results
Nested multiple linear regression indicated that the higher mindfulness levels predicted opioid misuse risk while controlling for pain severity, pain-related interference, pain anxiety, and acceptance. The full regression model predicted 54% of the variance in OA misuse risk.
Conclusion
Results suggest that psychological flexibility, particularly mindfulness processes, may be important in predicting and mitigating OA misuse risks among chronic pain patients. Non-pharmacological interventions are critical to addressing the current opioid misuse crisis.
