目的：为青少年强迫症(OCD)制定一种快速、经济有效的筛查方法。方法：采用20个条目的Leyton强迫量表-儿童版和心境与感觉问卷，由5组青少年组成：DSM-IV诊断为强迫症的青少年组(n=9)、伴有强迫症的重度抑郁障碍组(n=14)、不伴有强迫症的重度抑郁障碍组(n=65)、包括精神疾病高危人群的社区样本(n=253)和正常对照组(n=50)。对社区样本(n=253)的Leyton强迫症问卷得分进行因素分析，而其余组的得分作为验证。结果：因子分析得到了一个稳健的11项解，三个不同的成分解释了总方差的47.6%。短量表的内部信度较高(Cronbachα=.86)和三个分量表：强迫(α=.73)、强迫/不完整(α=.79)和洁净度(α=.75)。Logistic回归分析发现，强迫量表可区分强迫症和社区对照，区分有无强迫症的重度抑郁障碍。强迫症子量表将强迫症患者与社区、良好控制和抑郁的非强迫症组区分开来。结论：简短的莱顿强迫症儿童版是一种心理测量学上可靠、快速、经济的筛查方法，可以区分强迫症患者和非强迫症患者，而不考虑是否合并严重抑郁障碍。
Objective: To develop a short, cost-effective screening measure for adolescent obsessive-compulsive disorder (OCD). Method: The 20-item Leyton Obsessional Inventory-Child Version and the Mood and Feelings Questionnaire were completed by five groups of adolescents: those with a predominant DSM-IV diagnosis of OCD (n = 9), major depressive disorder with comorbid OCD (n = 14), major depressive disorder without comorbid OCD (n = 65), a community sample including subjects at high risk for psychopathology (n = 253), and well controls (n = 50). Leyton Obsessional Inventory scores for the community sample (n = 253) were factor analyzed, whereas the remaining groups' scores served as validation. Results: Factor analysis yielded a robust 11-item solution with three distinct components accounting for 47.6% of total variance. Internal reliability was high for the short scale total (Cronbach alpha = .86) and three subscales: Compulsions (alpha = .73), Obsessions/Incompleteness (alpha = .79), and Cleanliness (alpha = .75). Logistic regression found the Compulsions subscale discriminated OCD cases from community controls and discriminated major depressive disorder with and without comorbid OCD. The Obsessions subscale discriminated OCD cases from community, well control, and depressed nonobsessional groups. Conclusions: The Short Leyton Obsessional Inventory-Child Version is a psychometrically sound, quick, economical screen that discriminates OCD cases from noncases irrespective of comorbid major depressive disorder.
