The World Health Organization Disability Assessment Schedule (WHO DAS II) is a new measure of disability based on the ICIDH-2 model of functioning and disability. This study evaluates the measurement properties of the WHO DAS II in two disorders commonly encountered in the primary care setting. Seventy-three patients with depression and 76 patients with back pain were interviewed at baseline and after 3 months of usual primary care. Internal validity, convergent validity, and responsiveness to change of the WHO DAS II were evaluated. The WHO DAS II had excellent internal validity and convergent validity in the primary care setting. The responsiveness to change of the WHO DAS II was comparable to that of the SF-36. The WHO DAS II appears to be a useful health status instrument for measuring the disability associated with both physical and mental disorders in the primary care setting. This instrument facilitates the use of the ICIDH-2 as a framework for evaluating activity limitations and participation.
世界卫生组织残疾评定量表（WHO DAS II）是一种基于《国际功能、残疾和健康分类》第二版（ICIDH-2）功能与残疾模型的新型残疾评定工具。本研究评估了WHO DAS II在基层医疗环境中常见的两种疾病中的测量特性。对73例抑郁症患者和76例背痛患者在基线时以及接受3个月常规基层医疗后进行了访谈。评估了WHO DAS II的内部效度、收敛效度以及对变化的反应性。WHO DAS II在基层医疗环境中具有出色的内部效度和收敛效度。WHO DAS II对变化的反应性与SF-36相当。WHO DAS II似乎是一种用于测量基层医疗环境中与身心疾病相关残疾的有用健康状况工具。该工具便于将ICIDH-2用作评估活动受限和参与情况的框架。
