Background: Isolating a therapeutic procedure might be a powerful way to enhance our understanding of how cognitive behavior therapy (CBT) works. The present study explored new methods to isolate cognitive procedures and to study their direct impact on hypothesized underlying processes and CBT outcome. Method: The effects of a cognitive therapy skill acquisition procedure (n = 36) were compared to no procedure (n = 36) on cognitive therapy skills, dysfunctional thinking, distress, and mood in response to induced distress following a social stress test in healthy participants. Results: Participants reported more cognitive therapy skills after the procedure that focused on the acquisition of cognitive therapy skills compared to no procedure, but there were no differences in dysfunctional thinking, distress, and mood between the groups. Conclusions: By demonstrating an experimental approach to investigate mechanisms of change, including the pitfalls that come along with it, the present experiment provides a blueprint for other researchers interested in the underlying mechanisms of change in CBT for depression.

隔离治疗程序以研究抑郁症认知行为疗法变化的机制

背景：隔离治疗程序可能是增强我们对认知行为疗法（CBT）运作方式的了解的有力方法。本研究探索了隔离认知程序并研究其对假设的潜在过程和CBT结果的直接影响的新方法。方法：在健康压力下，通过社交压力测试，比较了认知疗法技能获取程序（n = 36）与无流程（n = 36）对认知疗法技能，思维障碍，苦恼和情绪对诱发苦恼的反应的效果参与者。结果：与无手术相比，参与者报告的手术后专注于认知治疗技能的掌握的认知治疗技能更多，但是两组之间在功能障碍思维，痛苦和情绪上没有差异。结论：
