This study examined the psychometric properties of the Obsessive-Compulsive Scale (OCS) of the Child Behavior Checklist (CBCL). Participants included 48 youth with obsessive-compulsive disorder (OCD), 41 with a non-OCD internalizing disorder, and 101 with an externalizing disorder. Confirmatory factor analysis of the 8-item OCS did not result in an adequate fit. Exploratory factor analysis identified a 1-factor model consisting of 6 items. Adequate internal consistency for the revised OCS (OCS-R) was obtained, and convergent validity was supported by moderate relationships with other OCD indices. The OCS-R had stronger associations with measures of OCD symptoms than with measures of depression and externalizing behaviors. Youth with OCD had significantly higher OCS-R scores than those with internalizing and externalizing disorders. Suggestions for cutoff scores are provided using results from ROC analyses. Overall, these findings suggest that the OCS-R is a reliable and valid instrument for the assessment of pediatric OCD.
本研究检验了儿童行为量表（CBCL）中强迫量表（OCS）的心理测量特性。参与者包括48名患有强迫症（OCD）的青少年、41名患有非OCD内化障碍的青少年以及101名患有外化障碍的青少年。对8项OCS进行的验证性因素分析未得出充分拟合结果。探索性因素分析确定了一个由6项组成的单因素模型。修订后的OCS（OCS-R）获得了足够的内部一致性，并且与其他OCD指标的适度相关性支持了其收敛效度。OCS-R与OCD症状测量指标的关联强于与抑郁和外化行为测量指标的关联。患有OCD的青少年的OCS-R得分显著高于患有内化和外化障碍的青少年。利用ROC分析结果提供了临界值分数的建议。总体而言，这些发现表明OCS-R是评估儿童OCD的可靠且有效的工具。
