The present study examined whether pain catastrophizing and pain acceptance, two important targets of psychosocial interventions for chronic pain, are uniquely associated with pain severity and pain interference among patients on methadone maintenance treatment (MMT).
A total of 133 MMT patients who reported experiencing some pain during the previous week completed a battery of self-report measures. Multiple regression was used to test whether pain catastrophizing and pain acceptance are related to pain severity and pain interference above and beyond covariates including demographics, emotional distress, and current methadone dose.
Both pain acceptance and catastrophizing were significantly associated with pain severity and pain interference while controlling for covariates.
Consistent with previous literature on patients with chronic pain but without opioid use disorder, our findings suggest that both pain catastrophizing and pain acceptance are potentially important intervention targets among MMT patients with co-occurring opioid use disorder and chronic pain.
本研究旨在探讨在接受美沙酮维持治疗（MMT）的患者中，疼痛灾难化和疼痛接受这两个心理社会干预的重要目标是否与疼痛严重程度和疼痛干扰具有独特的相关性。
共有 133 名在过去一周内报告有疼痛经历的 MMT 患者完成了一系列自我报告的测量。多元回归用于测试疼痛灾难化和疼痛接受是否与疼痛严重程度和疼痛干扰有关，这些因素包括人口统计学、情绪困扰和当前美沙酮剂量等。
在控制协变量的情况下，疼痛接受和灾难化都与疼痛严重程度和疼痛干扰显著相关。
与以前关于慢性疼痛但没有阿片类药物使用障碍的患者的文献一致，我们的研究结果表明，在同时患有阿片类药物使用障碍和慢性疼痛的 MMT 患者中，疼痛灾难化和疼痛接受都是潜在的重要干预目标。
