The inference-based approach (IBA) is one cognitive model that aims to explain the aetiology and maintenance of obsessive-compulsive disorder (OCD). The model proposes that certain reasoning processes lead an individual with OCD to confuse an imagined possibility with an actual probability, a state termed inferential confusion. One such reasoning process is inverse reasoning, in which hypothetical causes form the basis of conclusions about reality. Although previous research has found associations between a self-report measure of inferential confusion and OCD symptoms, evidence of a specific association between inverse reasoning and OCD symptoms is lacking. In the present study, we developed a task-based measure of inverse reasoning in order to investigate whether performance on this task is associated with OCD symptoms in an online sample. The results provide some evidence for the IBA assertion: greater endorsement of inverse reasoning was significantly associated with OCD symptoms, even when controlling for general distress and OCD-related beliefs. Future research is needed to replicate this result in a clinical sample and to investigate a potential causal role for inverse reasoning in OCD.
基于推理的方法（IBA）是一种旨在解释强迫症（OCD）病因和维持的认知模型。该模型提出，某些推理过程会导致 OCD 患者将想象中的可能性与实际的可能性混淆，这种状态称为推理混淆。其中一种推理过程是反向推理，在这种推理过程中，假设的原因构成了对现实的结论的基础。尽管先前的研究已经发现了推理混淆的自我报告测量与 OCD 症状之间的关联，但反向推理与 OCD 症状之间存在特定关联的证据尚缺乏。在本研究中，我们开发了一种基于任务的反向推理测量方法，以调查在线样本中，这种任务的表现是否与 OCD 症状相关。结果为 IBA 的主张提供了一些证据：反向推理的更多认可与 OCD 症状显著相关，即使在控制一般困扰和 OCD 相关信念后也是如此。需要进一步的研究来在临床样本中复制这一结果，并调查反向推理在 OCD 中的潜在因果作用。
