In addition to the central role of compulsive behaviors in obsessive compulsive disorder (OCD), recent data have documented the presence of compulsive behaviors in individuals with generalized anxiety disorder (GAD). However, there is a lack of information about potential similarities and differences with regard to the quality, or content, of checking associated with worry and obsessions. The two studies presented herein are an initial step towards gathering this information. Findings of Study 1, from a large unselected undergraduate sample, showed that symptoms of OCD and GAD were both significantly associated with checking behaviors. However, while OCD symptoms were associated with checking related to both objects and interpersonal situations, GAD symptoms were only significantly associated with interpersonal checking. Findings of Study 2, using a separate sample, suggest links between interpersonal checking and features characteristic of GAD, namely emotion regulation difficulties, and between object checking and a cognitive feature of OCD, namely thought-action fusion. In summary, the current studies add to a growing body of literature suggesting that checking may be important in numerous forms of psychopathology, while also suggesting that the nature and function of checking may differ for various symptom profiles.
除了强迫行为在强迫症（OCD）中的核心作用外，最近的数据还记录了广泛性焦虑症（GAD）患者存在强迫行为。然而，关于与担忧和强迫观念相关的检查的质量或内容方面的潜在相似性和差异的信息还很缺乏。本文提出的两项研究是收集这些信息的初步步骤。第一项研究来自一个大型未选择的本科生样本，结果表明 OCD 和 GAD 的症状都与检查行为显著相关。然而，虽然 OCD 症状与对物体和人际情境的检查有关，但 GAD 症状仅与人际检查显著相关。第二项研究使用了一个独立的样本，结果表明人际检查与 GAD 的特征（即情绪调节困难）之间存在联系，而与物体检查与 OCD 的认知特征（即思维-行动融合）之间存在联系。总之，目前的研究增加了越来越多的文献，表明检查可能在多种精神病理学中很重要，同时也表明检查的性质和功能可能因各种症状特征而有所不同。
