Chronic, Non-neuropathic Back Pain
Conditions
Brief summary
The overarching aim of this project is to conduct a randomized controlled study to determine whether Mindfulness-Oriented Recovery Enhancement (MORE) vs. a Support Group (SG) can improve pain regulation and hedonic functions (i.e., natural reward responsiveness) thought to be governed by the endogenous opioid system among opioid-treated, chronic, non-neuropathic back pain patients (CNBP) and thereby improve clinical pain, affect, and opioid use.
Interventions
Mindfulness-Oriented Recovery Enhancement (MORE) is a group behavioral intervention that unites mindfulness training, cognitive reappraisal, and positive psychological principles into an integrative intervention strategy targeting mechanisms of pain and opioid misuse.
A conventional support group will allow participants to express emotions, share experiences, and receive social support under the guidance of a skilled therapist.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Changes in endogenous opioid system function in response to pain challenge | Change from week 0 to 8 weeks | PET opioid receptor binding potential from baseline through pain challenge |
| Changes in fMRI activity level during natural reward processing | Change from week 0 to 8 weeks | Blood oxygen dependent signal (BOLD) response during viewing and regulating response to natural reward cues measured during a fMRI scan. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Pain sensitivity as a measure of volume of hypertonic saline | Change from week 0 to 8 weeks | Volume of hypertonic saline to maintain pain at 40 out of 100 on a VAS |
| Self-report affect ratings | Change from week 0 to 8 weeks | — |
| Significant correlation between PET and fMRI measures with improvements in clinical pain, affect, and opioid use | Change from week 0 to 8 weeks | — |
