尽管强迫症 (OCD) 的现象学已广为人知，但对非临床人群强迫症状的结构却知之甚少。本研究以 1,015 名本科生为样本，考察了 Leyton Obsessional Inventory Short Form (LOI-SF) 的因子结构。提取了四个因素来描述对污染的担忧（标记为污染因素）；重复行为或不舒服的想法或怀疑（标记为怀疑/重复因素）；检查行为、过于关注细节、诚实关注、严格的良心和严格的常规（标记为“检查/细节因素”）；花很长时间穿衣、挂起和收起衣服，以及相信极其不吉利的数字（标记为“担忧/恰到好处”因素）。焦虑和多动症症状的自我报告测量与这些因素呈正相关，特别是与检查/细节因素。在未经选择的大学生样本中观察到的患病率、症状结构和合并症模式与患有强迫症的青少年中观察到的模式相似，表明强迫症状和强迫症可能沿着连续体存在。
Although the phenomenology of obsessive-compulsive disorder (OCD) is well understood, less is known about the structure of obsessive symptoms in nonclinical populations. The present study examines the factorial structure of the Leyton Obsessional Inventory short form (LOI-SF) in a sample of 1,015 undergraduate college students. Four factors were extracted describing concerns about contamination (labeled the Contamination factor); repeating behaviors or uncomfortable thoughts or doubts (labeled the Doubts/Repeating factor); checking behaviors, too much attention to detail, honesty concerns, strict conscience and strict routine (labeled the Checking/Detail factor); and taking a long time to dress and to hang up and put away clothing, as well as belief in extremely unlucky numbers (labeled Worries/Just Right factor). Self-report measures of anxiety and ADHD symptoms were correlated positively with these factors, particularly with the checking/detail factor. The prevalence, symptom structure, and patterns of comorbidity seen in this sample of unselected college students are similar to the patterns seen in adolescents with OCD, suggesting that obsessional symptoms and OCD may exist along a continuum.
