Health assessment measurements for patients with Rheumatoid arthritis (RA) have to be meaningful, valid and relevant. A commonly used questionnaire for patients with RA is the Stanford Health Assessment Questionnaire Disability Index (HAQ), which has been available in Swedish since 1988. The HAQ has been revised and improved several times and the latest version is the Multi Dimensional Health Assessment Questionnaire (MDHAQ). The aim of this study was to translate the MDHAQ to Swedish conditions and to test the validity and reliability of this version for persons with RA.
Translation and adaption of the MDHAQ were performed according to guidelines by Guillemin et al. The translated version was tested for face validity and test-retest in a group of 30 patients with RA. Content validity, criterion validity and internal consistency were tested in a larger study group of 83 patients with RA. Reliability was tested with test-retest and Cronbach´s alpha for internal consistency. Two aspects of validity were explored: content and criterion validity. Content validity was tested with a content validity index.Criterion validity was tested with concurrent validity by exploring the correlation between the MDHAQ-S and the AIMS2-SF. Floor and ceiling effects were explored.
Test-retest with intra-class correlation coefficient (ICC) gave a coefficient of 0.85 for physical function and 0.79 for psychological properties. Reliability test with Cronbach´s alpha gave an alpha of 0.65 for the psychological dimension and an alpha of 0.88 for the physical dimension of the MDHAQ-S.The average sum of the content validity index for each item was of the MDHAQ-S was 0.94. The MDHAQ-S had mainly a moderate correlation with the AIMS2-SF, except for the social dimension of the AIMS2-SF, which had a very low correlation with the MDHAQ-S.
The MDHAQ-S was considered to be reliable and valid, but further research is needed concerning sensitivity to change.
类风湿关节炎（RA）患者的健康评估测量必须具有意义、有效且相关。一种常用于 RA 患者的常用问卷是斯坦福健康评估问卷残疾指数（HAQ），自 1988 年以来，瑞典就有该问卷。HAQ 已经经过多次修订和改进，最新版本是多维健康评估问卷（MDHAQ）。本研究的目的是将 MDHAQ 翻译成瑞典语，并测试该版本对 RA 患者的有效性和可靠性。
根据 Guillemin 等人的指南进行 MDHAQ 的翻译和改编。在一组 30 名 RA 患者中对翻译后的版本进行了表面有效性和重测检验。在更大的 83 名 RA 患者研究组中测试了内容有效性、标准有效性和内部一致性。可靠性通过重测和 Cronbach's alpha 进行测试，以评估内部一致性。有效性的两个方面进行了探讨：内容和标准有效性。内容有效性通过内容有效性指数进行测试。标准有效性通过探索 MDHAQ-S 与 AIMS2-SF 之间的相关性来进行同时有效性测试。还探索了地板效应和天花板效应。
使用组内相关系数（ICC）进行重测，物理功能的系数为 0.85，心理属性的系数为 0.79。使用 Cronbach's alpha 进行可靠性测试，MDHAQ-S 的心理维度的 alpha 为 0.65，物理维度的 alpha 为 0.88。MDHAQ-S 的每个项目的内容有效性指数的平均值为 0.94。MDHAQ-S 与 AIMS2-SF 主要具有中等相关性，除了 AIMS2-SF 的社会维度与 MDHAQ-S 相关性非常低之外。
MDHAQ-S 被认为是可靠且有效的，但需要进一步研究其对变化的敏感性。
