强迫症的认知模型[OCD；例如，Rachman，1997，行为研究与治疗，35, 793-802； Salkovskis, 1985, 行为研究与治疗, 23, 571-583] 提出对侵入性思想和图像的负面解释对于强迫症的发展和维持至关重要。尽管一致的研究结果表明，特定的解释（例如，更高的责任）有助于维持 OC 症状 [参见 Salkovskis & Forrester，2002，理论、评估和治疗，纽约：Pergamon]，但没有研究检验这些解释在 OCD 发展中的作用，或者与 OCD 相关的信念是否可以预测症状水平的变化。在当前的研究中，377 名本科生参加了一项为期 6 周的前瞻性研究，他们完成了对强迫症相关信念、生活事件和强迫症症状的测量。与强迫症相关的信念和消极生活事件均显着预测了 6 周内强迫症症状的残余变化。然而，并不支持认知-脆弱性-压力之间的相互作用。探索性分析表明，与强迫症相关的信念可能比其他症状（例如囤积和清洗）更能预测某些特定类型的强迫症症状（例如中和、排序和痴迷）。这项研究的结果对于阐明强迫症症状水平变化的预测因素以及促进对强迫症易感性的研究非常重要。
Cognitive models of Obsessive-Compulsive Disorder [OCD; e.g., Rachman, 1997, Behaviour Research and Therapy, 35, 793-802; Salkovskis, 1985, Behaviour Research and Therapy, 23, 571-583] propose that negative interpretations of intrusive thoughts and images are central to the development and maintenance of OCD. Despite consistent findings that specific interpretations (e.g., heightened responsibility) contribute to the maintenance of OC symptoms [see Salkovskis & Forrester, 2002, Theory, assessment, and treatment, New York: Pergamon], no research has examined the role of these interpretations in the development of OCD or whether OCD-related beliefs predict changes in symptom levels. In the current study, 377 undergraduate students participated in a 6-week prospective study for which they completed measures of OCD-related beliefs, life events, and OC symptoms. OCD-related beliefs and negative life events each significantly predicted residual change in OC symptoms over 6-weeks. However, there was not support for a cognitive-vulnerability-stress interaction. Exploratory analyses suggest that OCD-related beliefs may be more predictive of some particular types of OCD symptoms (e.g., neutralizing, ordering, and obsessing) than others (e.g., hoarding and washing). Findings from this study are important for clarifying predictors of changes in OCD symptom levels and for stimulating research on vulnerability to OCD.
