背景资料：抑郁症初级保健（PC）患者的世界卫生组织残疾评估表II（WHO-DAS II）的心理测量信息是稀缺的，并已获得与36项版本的工具。本研究的主要目的是分析的维度，内部一致性和结构效度的12项WHO-DAS II在一个大样本的西班牙PC患者首次诊断为重度depression episode.Method：数据收集2006年12月和2007年7月之间。共有3615名来自西班牙17个地区的首次诊断为重度抑郁发作的成年（18岁或以上）PC患者参加了这项研究。12项WHO-DAS II和一组评估社会人口学特征、抑郁严重程度（PHQ-9）、生活质量（EQ-5D）和慢性健康状况的工具由家庭医生在咨询期间进行管理。该工具显示了足够的内部一致性（α =0.89）和结构效度，因为它是显着相关的生活质量和抑郁症的严重程度（收敛效度），并能够区分病人的病假和那些正在工作（区分效度）。局限性：的重测信度和灵敏度变化的仪器没有检查，由于横断面设计的study.Conclusions：12项WHO-DAS II是一个可靠的，有效的和有用的工具，用于评估整体残疾的PC抑郁症患者。(C)2009 Elsevier B.

Background: Psychometric information on the World Health Organization Disability Assessment Schedule II (WHO-DAS II) in depressive primary care (PC) patients is scarce and has been obtained with the 36-item version of the instrument. The main objective of this study was to analyse the dimensionality, internal consistency and construct validity of the 12-item WHO-DAS II in a large sample of Spanish PC patients with a first diagnosed major depressive episode.Method: Data were collected between December 2006 and July 2007. A total of 3615 adult (18 years or older) PC patients from 17 regions of Spain with a first diagnosed major depressive episode participated in the study. The 12-item WHO-DAS II and a battery of instruments assessing sociodemographic characteristics, depression severity, (PHQ-9), quality of life (EQ-5D) and chronic health conditions were administered by the family physician during the consultation.Results: The principal component analysis and the subsequent confirmatory factor analysis indicated that the 12-item WHO-DAS 11 is one-dimensional. The instrument showed adequate internal consistency (alpha=0.89) and construct validity because it was significantly associated with quality of life and depression severity (convergent validity) and was able to discriminate between patients on sick leave and those that were working (discriminative validity). Limitations: The test-retest reliability and sensitivity to change of the instrument was not examined due to the cross-sectional design of the study.Conclusions: The 12-item WHO-DAS II is a reliable, valid and useful tool for assessing overall disability in PC patients with depression.
