The Yale-Brown Obsessive-Compulsive Scale (Y-BOCS; Goodman, Price, Rasmussen, Mazure, Delgado, et al., 1989) is acknowledged as the gold standard measure of obsessive-compulsive disorder (OCD) symptom severity. A number of areas where the Y-BOCS may benefit from revision have emerged in past psychometric studies of the Severity Scale and Symptom Checklist. Therefore, we created the Yale-Brown Obsessive-Compulsive Scale-Second Edition (Y-BOCS-II) by revising the Severity Scale item content and scoring framework, integrating avoidance into the scoring of Severity Scale items, and modifying the Symptom Checklist content and format. One hundred thirty treatment-seeking adults with OCD completed a battery of measures assessing OCD symptom severity and typology and depressive and anxious symptomology. Interrater and test-retest reliability were assessed on a subsample of participants. The Y-BOCS-II showed strong internal consistency for the Symptom Checklist (Kuder-Richardson-20 = .91) and Severity Scale (alpha = .89). Test-retest and interrater reliabilities were both high (intraclass correlations > .85). Confirmatory factor analyses did not show adequate fit with previous models of the Y-BOCS. Exploratory factor analysis revealed a two-factor solution generally consistent with the Obsession and Compulsion Severity subscales. Construct validity was supported by strong correlations with clinician-rated measures of OCD symptom severity and moderate correlations with measures of worry and depressive symptoms. Taken together, the Y-BOCS-II has excellent psychometric properties in assessing the presence and severity of obsessive-compulsive symptoms. Although the Y-BOCS remains a reliable and valid measure, the Y-BOCS-II may provide an alternative method of assessing symptom presence and severity.
耶鲁-布朗强迫症量表（Y-BOCS；Goodman、Price、Rasmussen、Mazure、Delgado 等人，1989）被公认为强迫症（OCD）严重程度的金标准测量工具。在过去对严重程度量表和症状清单的心理测量研究中，出现了一些 Y-BOCS 可能需要修订的领域。因此，我们通过修订严重程度量表项目内容和评分框架、将回避纳入严重程度量表项目评分、以及修改症状清单内容和格式，创建了耶鲁-布朗强迫症量表第二版（Y-BOCS-II）。130 名寻求治疗的强迫症成年人完成了一系列评估 OCD 症状严重程度和类型以及抑郁和焦虑症状的量表。对部分参与者进行了评分者间信度和重测信度评估。Y-BOCS-II 对症状清单（Kuder-Richardson-20 =.91）和严重程度量表（alpha =.89）具有很强的内部一致性。重测和评分者间信度都很高（组内相关系数 >.85）。验证性因子分析显示与之前的 Y-BOCS 模型不太适配。探索性因子分析显示出一个两因素解决方案，通常与强迫观念和强迫行为严重程度子量表一致。结构有效性得到了与临床评定的 OCD 症状严重程度量表的强相关性以及与担忧和抑郁症状的中度相关性的支持。总的来说，Y-BOCS-II 在评估强迫症状的存在和严重程度方面具有优异的心理测量特性。尽管 Y-BOCS 仍然是一种可靠且有效的测量工具，但 Y-BOCS-II 可能提供了一种评估症状存在和严重程度的替代方法。
