The reliability and validity of the Yale-Brown Obsessive-Compulsive Scale were examined according to a multi-trait multi-method approach in a sample of 54 outpatients with obsessive-compulsive disorder (OCD). Internal consistency was acceptable but was improved by deletion of items concerning resistance to obsessions and compulsions. Inter-rater reliability was excellent, but test-retest reliability over an average interval of 48.5 days was lower than desirable. The YBOCS demonstrated good convergent validity with most other measures of OCD, but divergent validity vis à vis depression was poor. Analyses of new items assessing avoidance and the duration of obsession-free and compulsion-free intervals indicated that only the avoidance rating added meaningfully to the full scale score. In future research the authors recommend deletion of the resistance items and inclusion of the avoidance item to yield a revised 9-item YBOCS total score.
采用多特质多方法 approach，在54名强迫症（OCD）门诊患者样本中检验了耶鲁-布朗强迫量表的信度和效度。内部一致性尚可，但删除有关对强迫观念和强迫行为抵抗的条目后有所改善。评定者间信度极佳，但平均间隔48.5天的重测信度低于理想水平。YBOCS与大多数其他OCD测量方法显示出良好的聚合效度，但与抑郁的区分效度较差。对评估回避以及无强迫观念和无强迫行为间隔时长的新条目的分析表明，只有回避评分对全量表得分有显著意义。作者在未来研究中建议删除抵抗条目并纳入回避条目，以得出修订后的9项YBOCS总分。
