目的强迫症包括一系列广泛的症状，代表多个心理领域，包括知觉，认知，情感，社会关系和各种运动行为。这些分析的目的是评估强迫症症状的相关关系。方法本研究在两个独立的强迫症患者组（N = 208和N = 98）中检查了Yale-Brown强迫量表症状自评量表中用于分组强迫症和强迫类型的13个先验类别。进行了方差最大旋转的主成分因子分析，然后进行了一系列其他探索性分析。结果两个数据集得到了几乎相同的结果。每个数据集中出现了四个因素--痴迷和检查、对称和有序、清洁和清洗以及寄宿，总共占方差的60%以上。结论：强迫症是一个多方面的和病因异质性的条件。在这项研究中确定的四个症状维度在很大程度上与早期报告中确定的一致。这些因素可能在未来的遗传学，神经生物学和治疗反应的研究价值。
OBJECTIVE Obsessive-compulsive disorder encompasses a broad range of symptoms that represent multiple psychological domains, including perception, cognition, emotion, social relatedness, and diverse motor behaviors. The purpose of these analyses was to evaluate the correlational relationships of the symptoms of obsessive-compulsive disorder. METHOD This study examined the 13 a priori categories used to group types of obsessions and compulsions in the Yale-Brown Obsessive Compulsive Scale symptom checklist in two independent groups of patients with obsessive-compulsive disorder (N = 208 and N = 98). A principal-components factor analysis with varimax rotation was performed, followed by a series of other exploratory analyses. RESULTS The two data sets yielded nearly identical results. Four factors--obsessions and checking, symmetry and ordering, cleanliness and washing, and boarding--emerged in each data set, in total accounting for more than 60% of the variance. CONCLUSIONS Obsessive-compulsive disorder is a multidimensional and etiologically heterogeneous condition. The four symptom dimensions identified in this study are largely congruent with those identified in earlier reports. These factors may be of value in future genetic, neurobiological, and treatment response studies.
