目标。目的：评价硬皮病试验中健康评估问卷(HAQ)残疾指数(DI)的测量特性，并确定硬皮病健康评估问卷(ShaQ)视觉模拟量表是否具有比HAQ DI更好的测量优势。计算机检索描述Haq DI和Shaq在硬皮病中的使用的文章。对支持这些测量方法的敏感性、可靠性、效度和反应性的证据进行评估。与Haq DI相比，Shaq具有增加的表面和内容有效性，因为它解决了硬皮病的特定表现，这些表现也有助于残疾。HAQ DI具有良好的同时效度、结构效度和预测效度。沙克是否赋予HAQ DI的增量结构、并发或预测效度是不确定的。HAQ DI似乎比Shaq更可靠；然而，可靠性研究提供的数据不足以确定是否达到了最低标准。HAQ DI子量表的反应性已得到证实。与Haq DI相比，Shaq在表面和内容上的有效性都有所增加。HAQ IN具有更高的信度，并证明了结构效度、同时效度和预测效度。需要进一步研究HAQ DI和Shaq视觉模拟标尺的测量特性，以及它们与所要求的测量标准的关系。
Objective. To evaluate the measurement properties of the Health Assessment Questionnaire (HAQ) disability index (DI) for group comparisons in scleroderma trials, and to determine if the Scleroderma Health Assessment Questionnaire (SHAQ) visual analog scales confer any measurement advantage over the HAQ DI.Methods. A computer search for articles describing the use of the HAQ DI and SHAQ in scleroderma was performed. Evidence supporting the sensibility, reliability, validity, and responsiveness of these measures was evaluated.Results. The SHAQ has incremental face and content validity over the HAQ DI because it addresses scleroderma-specific manifestations that also contribute to disability. The HAQ DI has good concurrent validity, construct validity, and predictive validity. Whether SHAQ confers incremental construct, concurrent, or predictive validity over the HAQ DI is uncertain. The HAQ DI appears more reliable than the SHAQ; however, reliability studies provide insufficient data to ascertain if minimum standards have been achieved. Responsiveness of the HAQ DI subscales hits been demonstrated.Conclusion. The SHAQ has incremental face and content validity over the HAQ DI. The HAQ IN has greater reliability and demonstrated construct, concurrent, and predictive validity. Further investigation into the measurement properties of the HAQ DI and SHAQ visual analog scales, and their relation to the required standards of measurement is needed.
