Obsessive-compulsive (OCD) and delusional disorders (DD) have been recognised with increased frequency in recent years, and the propensity of some OCD subjects to become deluded has become a focus of interest. This study reports illness-specific demography along with measures of symptom severity and tests to assess schizotypal ideation, dysfunctional attitudes, attributional and attention bias in 30 patients with OCD, 29 with DD, 16 with OCD with delusions (OC-DD) and a 30-subject control group (CG). Obsessional features appeared before delusions in the OC-DD group, suggesting that OCD was the primary pathology. Delusions were more likely in subjects obsessional about one rather than multiple themes. There was some support for proposals that depression and schizotypy may bring out delusions in OCD and some evidence for the utility of categorising OCD according to the number of obsessions a subject has.
近年来，强迫症（OCD）和妄想障碍（DD）的确诊率日益升高，部分强迫症患者出现妄想的倾向已成为研究热点。本研究报告了30例强迫症患者、29例妄想障碍患者、16例伴有妄想的强迫症患者（OC-DD）以及一个30人的对照组（CG）的疾病特异性人口统计学数据、症状严重程度测量结果，以及用于评估分裂型观念、功能失调性态度、归因和注意偏差的测试。在OC-DD组中，强迫观念先于妄想出现，提示强迫症是主要病理。相比于多个主题，专注于单一主题的患者更易出现妄想。有证据支持抑郁和分裂型人格可能引发强迫症患者的妄想，也有证据表明根据患者强迫观念的数量对强迫症进行分类具有一定作用。
