以接受为基础的方法已经证明有希望改善肥胖行为治疗的结果，但很少有研究检查这些治疗的变化过程。关键是确定治疗中的作用机制，以进一步优化这种方法，完善理论，并为未来的研究提供信息。本研究在一项基于接受度的行为减肥治疗的随机对照试验中检查了心理灵活性的几个特定领域和一般措施的变化。这些指标的变化与减肥结果之间的关系也进行了研究。成人（N = 283）随机接受12个月的基于接受（ABT）或非基于接受（非ABT）的行为治疗，并在第0、6和12个月完成一般和体重控制特定心理灵活性的测量。与非ABT的参与者相比，ABT的参与者在治疗期间表现出与饮食和身体活动经历相关的更大的心理灵活性，这些过程的变化与更好的体重减轻有关。平行中介分析进一步表明，饮食和身体活动经历相关的心理灵活性部分介导了治疗状况与12个月体重减轻之间的关系。不同条件下的参与者也经历了一般心理灵活性的小幅增加，但一般心理灵活性与减肥结果没有意义的关系。这些发现表明，特定领域（相对于一般）的心理灵活性可能受ABT的影响最大，与减肥结果最相关。研究结果也为ABT用于体重管理的理论模型提供了部分支持。
Acceptance-based approaches have demonstrated promise for improving outcomes in behavioral treatments for obesity, but few studies have examined processes of change in these treatments. It is critical to identify mechanisms of action in treatment to further optimize this approach, refine theory, and inform future research. This study examined change in several domain-specific and general measures of psychological flexibility in a randomized controlled trial of an acceptance-based behavioral weight loss treatment. The relationships between change in these measures and weight loss outcomes were also examined. Adults (N = 283) were randomized to receive 12 months of acceptance-based (ABT) or non-acceptance-based (non-ABT) behavioral treatment and completed measures of general and weight control-specific psychological flexibility at months 0, 6, and 12. Participants in ABT demonstrated greater increases in psychological flexibility related to eating and physical activity experiences during treatment compared to participants in non-ABT, and changes in these processes were correlated with better weight loss. Parallel mediation analyses further revealed that psychological flexibility related to eating and physical activity experiences partially mediated the relationship between treatment condition and 12-month weight loss. Participants across conditions also experienced small increases in general psychological flexibility, but general psychological flexibility was not meaningfully related to weight loss outcomes. These findings indicate that domain-specific (versus general) psychological flexibility may be most impacted by ABT and most relevant to weight loss outcomes. Results also provide partial support for the theoretical model of ABT for weight management.
