Several articles have recently questioned the distinction between acceptance and commitment therapy (ACT) and traditional cognitive therapy (CT). This study presents a reanalysis of data from Zettle and Rains that compared 12 weeks of group CT with group ACT. For theoretical reasons, Zettle and Rains also included a modified form of CT that did not include distancing, and no intent-to-treat analysis was included. Particularly because that unusual third condition did somewhat better than the full CT package, it contaminated the direct comparison of ACT and CT, which has of late become theoretically interesting. In the present study, data from participants in the ACT and CT conditions were reanalyzed. ACT was shown to produce greater reductions in levels of self-reported depression using an intent-to-treat analysis. Posttreatment levels of cognitive defusion mediated this effect at follow-up. The occurrence of depressogenic thoughts and level of dysfunctional attitudes did not function as mediators. This study adds additional evidence that ACT works through distinct and theoretically specified processes that are not the same as CT.
最近有几篇文章质疑接纳与承诺疗法 (ACT) 和传统认知疗法 (CT) 之间的区别。本研究重新分析了 Zettle 和 Rains 的数据，这些数据比较了为期 12 周的小组 CT 与小组 ACT。出于理论原因，Zettle 和 Rains 还包括了一种不包括距离的改良 CT 形式，并且没有进行意向治疗分析。特别是因为那个不寻常的第三种情况比完整的 CT 方案稍好一些，它污染了 ACT 和 CT 的直接比较，这在最近变得具有理论意义。在本研究中，对 ACT 和 CT 条件下的参与者数据进行了重新分析。使用意向治疗分析显示，ACT 可使自我报告的抑郁水平降低更多。在随访时，认知离解的后处理水平中介了这种效果。抑郁性思维的发生和功能失调态度的水平没有作为中介。本研究增加了更多证据表明，ACT 通过与 CT 不同的、理论上指定的过程起作用，而这些过程与 CT 不同。
