Abstrakt:	Little is known about the mechanisms by which pain catastrophizing may be associated with opioid use outcomes. This study aimed to investigate the potential mediating role of beliefs about the appropriateness of pain medicines for pain treatment on the association between pain catastrophizing and prescription opioid use in a community chronic non-cancer pain (CNCP) sample. Individuals (N = 420) diagnosed with CNCP participated in a cross-sectional online self-report study with validated measures of pain medication beliefs, pain catastrophizing, and current prescription opioid use. Two parallel multiple mediator analyses with percentile-based bootstrapping examined pathways to both prescription opioid use and high-dose use (≥ 100mg oral morphine equivalents/day), while controlling for pain intensity and other relevant covariates. Pain medication beliefs significantly mediated the association between pain catastrophizing and prescription opioid use (CI = 0.011, 0.033). A similar pattern of findings was found for high-dose opioid use, with pain medication beliefs significantly mediating the pain catastrophizing-high-dose use association (CI = 0.006, 0.050). Pain medication beliefs are a potentially modifiable psychological mechanism by which pain catastrophizing is associated with opioid use, including high-dose use. These findings have important implications for personalizing prevention and treatment programs. (Copyright © 2021 United States Association for the Study of Pain, Inc. Published by Elsevier Inc.
