Group differences (mean with 95% confidence interval) in endorsement of A. pain as a major reason for continuing opioid use, B. needing more and more opioids to control pain, C. delaying OUD treatment for fear that pain will be worse when stopping opioids, and D. worry about pain-precipitated OUD relapse by ACR-FMS cut point ≥13 (consistent with fibromyalgia).
