The high prevalence and morbidity of obsessive compulsive disorder (OCD) in youth, the secretive nature of the disorder leading to under-recognition, and the lack of specialized child psychiatry services in many areas suggest that a simple, quick, and reliable screening tool to identify cases could be very useful to clinicians who work with children.
We used 8 items from the Child Behavior Checklist (CBCL), an empirically derived instrument free of clinician bias, to investigate the usefulness of a previously reported CBCL-based obsessive compulsive scale (OCS) by Nelson et al [Nelson EC, Hanna GL, Hudziak JJ, Botteron KN, Heath AC, Todd RD. Obsessive-compulsive scale of the Child Behavior Checklist: Specificity, sensitivity, and predictive power. Pediatrics 2001;108(1):E14] in a separate cohort of youth with OCD. We computed the psychometric properties of the OCS in our sample of youth with OCD and in psychiatric and normal controls, and compared these to the published values.
Using the recommended cutoff between the 60th and 70th percentiles of the OCS to best predict the presence of OCD, we found very high sensitivity (92%-78%), specificity (86%-94%), negative predictive value (96%-90%), and positive predictive value (77%-86%).
The OC scale of the CBCL shows good reliability and validity and acceptable psychometric properties to help discriminate youth with OCD.
青少年强迫症（OCD）的高患病率和发病率、该疾病的隐匿性导致其未被充分认识，以及许多地区缺乏专业的儿童精神病学服务，这表明一种简单、快速且可靠的筛查工具对于从事儿童工作的临床医生非常有用。
我们使用了儿童行为量表（CBCL）中的8个项目，这是一种基于实证得出且无临床医生偏差的工具，以研究Nelson等人[Nelson EC, Hanna GL, Hudziak JJ, Botteron KN, Heath AC, Todd RD.儿童行为量表的强迫观念及强迫行为量表：特异性、敏感性和预测能力。《儿科学》2001年；108(1):E14]先前报道的基于CBCL的强迫观念及强迫行为量表（OCS）在另一组患有强迫症的青少年中的有用性。我们计算了OCS在我们患有强迫症的青少年样本以及精神病学和正常对照组中的心理测量特性，并将这些与已发表的值进行比较。
使用OCS第60至70百分位数之间的推荐临界值来最佳预测强迫症的存在，我们发现其敏感性（92% - 78%）、特异性（86% - 94%）、阴性预测值（九十六% - 90%）和阳性预测值（77% - 86%）都非常高。
CBCL的OC量表显示出良好的可靠性和有效性以及可接受的心理测量特性，有助于鉴别患有强迫症的青少年。
