This study examined the psychometric properties of the Children's Yale-Brown Obsessive-Compulsive Scale (CY-BOCS; Scahill et al., 1997). Participants were 82 children and adolescents diagnosed with obsessive-compulsive disorder (OCD). Confirmatory factor analyses of 2 previously found models (Obsessions and Compulsions; Disturbance and Severity) yielded poor fit indexes. Exploratory factor analysis supported a model of severity and disturbance with slightly different item content than found by McKay et al. (2003). The internal consistency of the factors was acceptable, and the convergent and divergent validity was supported vis-a-vis correlations with clinician ratings of impairment, self-report measures of depression and anxiety, and parent ratings of Tourette's disorder (TD) symptoms. These findings suggest that the CY-BOCS Total Score may represent an inaccurate assessment of symptom severity and supports the use of the revised Severity and Disturbance factors in assessing illness severity.
本研究检验了儿童耶鲁-布朗强迫症状量表（CY-BOCS；斯卡希尔等人，1997年）的心理测量特性。参与者为82名被诊断患有强迫症（OCD）的儿童和青少年。对之前发现的2种模型（强迫观念与强迫行为；干扰与严重程度）进行的验证性因素分析得出了拟合指数不佳的结果。探索性因素分析支持了一个严重程度和干扰模型，其项目内容与麦凯等人（2003年）发现的略有不同。各因素的内部一致性是可接受的，并且通过与临床医生对损害的评定、抑郁和焦虑的自我报告测量以及父母对抽动秽语障碍（TD）症状的评定之间的相关性，支持了收敛效度和区分效度。这些发现表明，CY-BOCS总分可能代表了对症状严重程度的不准确评估，并支持在评估疾病严重程度时使用修订后的严重程度和干扰因素。
