There is now a consensus in the literature that future improvements in outcomes obtained from cognitive behavioral therapy (CBT) for chronic pain will require research to identify patient and treatment variables that help explain outcomes. The first aim of this study was to assess whether pre-treatment scores on measures of psychological (in)flexibility, acceptance, committed action, cognitive (de)fusion, and values-based action predict outcomes in a multidisciplinary, multicomponent, group-based CBT program for adults with chronic pain. The second aim was to assess whether change scores on these same measures mediate outcomes in the treatment program. Participants were 232 people attending treatment for chronic pain. Of the psychological flexibility measures, only pre-treatment scores on the psychological inflexibility scale predicted outcomes; higher scores on this measure were associated with worse outcomes. However, change scores on each of the psychological flexibility measures separately mediated outcomes. The efficacy of CBT for chronic pain may be improved with a greater focus on methods that increase psychological flexibility.

现在，在文献中已经达成共识，即从对慢性疼痛的认知行为疗法（CBT）获得的治疗结果的未来改善中，将需要进行研究以识别有助于解释治疗结果的患者和治疗变量。这项研究的第一个目的是评估在心理（不）灵活性，接受性，承诺行动，认知（解散）和基于价值的行为等指标的治疗前分数是否能预测多学科，多成分，基于群体的结果针对患有慢性疼痛的成年人的CBT计划。第二个目的是评估在这些相同措施上的变化评分是否介导治疗方案中的结果。参加者有232人正在接受慢性疼痛治疗。在心理柔韧性测量中，只有在心理柔韧性量表上的治疗前分数可以预测结果。这项措施的分数越高，结果越差。但是，每个心理柔韧性测度的变化分数分别是介导的结果。CBT治疗慢性疼痛的疗效可能会得到提高，而更多地关注增加心理灵活性的方法。
