We examined the construction of the Yale-Brown Obsessive-Compulsive Scale (Y-BOCS) and performance of subscale items based on data from 204 patients with obsessive-compulsive disorder (OCD) who participated in a multicenter drug treatment study. Factor analysis was used to examine the relationship among the 10 items that make up the Y-BOCS instrument. Models were computed in which both two- and three-factor solutions were estimated. Within the two-factor solution analyses, the factor distribution was not so consistent as in the three-factor solution analyses, and a shift in the factor distribution was noted after treatment. In the three-factor solution analyses, an independent resistance construct emerged in addition to the obsessive and compulsive constructs. Examination of the postreatment factor scores showed that the Y-BOCS resistance items did not assess OCD symptom change as sensitively as the rest of the Y-BOCS items did.
我们基于204名参与多中心药物治疗研究的强迫症(OCD)患者的数据,对耶鲁-布朗强迫量表(Y-BOCS)的结构及分量表项目的表现进行了研究。采用因子分析来检验构成Y-BOCS工具的10个项目之间的关系。计算了估计两因素和三因素解决方案的模型。在两因素解决方案分析中,因子分布不如三因素解决方案分析中那样一致,并且在治疗后注意到因子分布发生了变化。在三因素解决方案分析中,除了强迫观念和强迫行为结构外,还出现了一个独立的抵抗结构。对治疗后因子得分的检查表明,Y-BOCS抵抗项目对OCD症状变化的评估不如Y-BOCS其他项目那样敏感。
