Unwanted intrusive thoughts (UITs) are considered normal variants of the obsessions found in obsessive–compulsive disorder (OCD). Similarly, intrusive and persistent preoccupations about appearance defects in body dysmorphic disorder (BDD) and images and thoughts about illness in illness anxiety disorder (IAD) are abnormal variants of the thoughts and concerns about appearance and health found in non-clinical individuals. This study examines whether patients with OCD have frequent and distressing UITs with contents related to BDD and IAD, in addition to OCD-related UITs.

强迫症患者的畸形和疾病焦虑相关的不想要的侵入性想法

不想要的侵入性想法 (UIT) 被认为是强迫症 (OCD) 中发现的强迫观念的正常变体。同样，对身体畸形障碍 (BDD) 的外观缺陷的侵入性和持续的关注以及对疾病焦虑症 (IAD) 中的疾病的图像和想法是非临床个体对外观和健康的想法和担忧的异常变体。本研究检查强迫症患者除了强迫症相关的 UIT 之外，是否有频繁且令人痛苦的 UIT，其内容与 BDD 和 IAD 相关。
