Precedent: Impairments in executive functioning may be associated with compulsive symptoms in Obsessive Compulsive Disorder (OCD). The aim of this study was to conduct a systematic review of cognitive flexibility, inhibitory control and working memory in OCD patients, using emotional and non-emotional paradigms. METHOD we reviewed research published in PubMed, Web of Science, PsychInfo, Scopus, Scielo, and ProQuest Psychology databases, from January 2008 to April 2019. The review followed a two-stage process. In the first stage, we selected only studies using neutral stimuli paradigms, while in the second we selected executive-emotional paradigms. RESULTS The first stage of the review provided 16 final results, while the second stage, with emotional stimuli, provided 3 results. CONCLUSIONS There is some initial evidence for the existence of executive impairments in OCD, as expressed in the performance and/or processing of working memory inhibitory control and cognitive flexibility. There is also initial evidence that these latter two could be modulated by the presentation or mental representation of negative valence stimuli or images, as well as the presence of aversive contingencies.

强迫症中的执行障碍：带有情绪和非情绪范例的系统评价。

先例：执行功能障碍可能与强迫症（OCD）有关。这项研究的目的是使用情感和非情感范式系统地评估强迫症患者的认知灵活性，抑制性控制和工作记忆。方法我们回顾了2008年1月至2019年4月发表在PubMed，Web of Science，PsychInfo，Scopus，Scielo和ProQuest Psychology数据库中的研究。该审查遵循两个阶段的过程。在第一阶段，我们只选择使用中性刺激范式的研究，而在第二阶段，我们选择执行情感范式。结果回顾的第一阶段提供16个最终结果，而第二阶段在情感刺激下提供3个结果。结论有一些初步的证据表明强迫症存在执行障碍，表现为工作记忆抑制控制和认知灵活性的表现和/或过程。也有初步证据表明，后两种可能会受到负价刺激或图像的呈现或心理表现以及厌恶性意外事件的影响而受到调节。
