Participants from the DSM-IV field trial for OCD (N = 381) were divided into two groups based on the SCID interview: those who met current criteria for obsessive-compulsive disorder (OCD) but not generalized anxiety disorder (GAD) and those who met current diagnostic criteria for both. The groups were compared on their severity of obsessive and compulsive symptoms, as well as on the percent of individuals who reported excessive worry concerning everyday issues (e.g. health, finances). The comorbidity rate was 20%. While the presence of GAD did not elevate OCD symptoms per se, it was associated with more pathological responsibility and indecisiveness. Excessive worries were significantly more common in those with comorbid OCD and GAD. The relationship between obsessions and worries is discussed.
参加《精神疾病诊断与统计手册》第四版强迫症现场试验的参与者（N = 381）根据结构化临床访谈被分为两组：一组符合当前强迫症（OCD）标准但不符合广泛性焦虑症（GAD）标准，另一组同时符合当前这两种疾病的诊断标准。对两组在强迫观念和强迫症状的严重程度以及报告对日常问题（如健康、财务）过度担忧的个体比例方面进行了比较。共病率为20%。虽然广泛性焦虑症的存在本身并未加重强迫症症状，但它与更多的病理责任感和犹豫不决有关。过度担忧在患有强迫症和广泛性焦虑症共病的个体中明显更为常见。文中还讨论了强迫观念与担忧之间的关系。
