Cognitive-behavioral models of obsessive-compulsive disorder (OCD) assume that obsessions have their origin in normal intrusive thoughts. These models propose that certain beliefs, such as thought-action fusion (TAF) beliefs, combined with the use of ineffective coping strategies, such as thought suppression, lead to the development of OCD. The purpose of the current study was to examine the relationship between these variables in a non-clinical sample in addition to exploring the effects of an alternative, acceptance-based coping strategy. This study explored the relationship between TAF beliefs, thought suppression, and OC-consistent symptoms via mediational analyses. Results showed that thought suppression mediated the relationship between TAF beliefs and OC-consistent symptoms. This study also experimentally examined the effects of various coping strategies (suppression, acceptance, or monitor-only) on the frequency of a distressing intrusion and appraisal ratings (e.g., anxiety, guilt, responsibility) after a TAF induction. Spontaneous suppression in the monitor-only group made comparisons of the experimental data difficult. However, analyses provided preliminary evidence suggesting that thought suppression is related to more intrusions, higher levels of anxiety, and negative appraisals, whereas an acceptance-based approach may be a useful alternative. Additional findings, limitations of the current study, and directions for future research are discussed.
强迫症（OCD）的认知行为模型假定，强迫观念源于正常的侵入性思维。这些模型提出，某些信念，如思维-行动融合（TAF）信念，与无效应对策略（如思维抑制）的使用相结合，会导致强迫症的发展。本研究的目的是在非临床样本中检验这些变量之间的关系，此外还探索一种基于接纳的替代应对策略的效果。本研究通过中介分析探讨了TAF信念、思维抑制和与强迫症相符的症状之间的关系。结果表明，思维抑制在TAF信念和与强迫症相符的症状之间起中介作用。本研究还通过实验检验了各种应对策略（抑制、接纳或仅监测）对TAF诱发后痛苦侵入的频率和评估评分（如焦虑、内疚、责任感）的影响。仅监测组的自发抑制使得实验数据的比较变得困难。然而，分析提供了初步证据，表明思维抑制与更多的侵入、更高水平的焦虑和负面评估有关，而基于接纳的方法可能是一种有用的替代方法。本文还讨论了其他研究结果、本研究的局限性以及未来研究的方向。
