The aim of this study was to assess the reliability and validity of the Disability of the Arm, Shoulder and Hand (DASH) questionnaire in a Swedish rheumatoid arthritis population.
To investigate the concurrent and convergent validity, 67 patients with rheumatoid arthritis completed the DASH, the Health Assessment Questionnaire Disability Index (HAQ) and activity-induced pain. Active shoulder-arm motion, handgrip force and disease activity (Disease Activity Score in 28 joints; DAS28) were assessed. The test-retest reliability was investigated in 26 patients. Face validity was also investigated.
Spearman’s correlation coefficient revealed a significant association (p < 0.001) between the DASH score and HAQ index (rs 0.80), confirming satisfactory concurrent validity. A significant association (p ≤ 0.02) was found between the DASH score and active shoulder-arm motion (rs –0.38 to –0.50), handgrip force (rs –0.46 to –0.59), activity-induced pain (rs 0.66) and DAS28 (rs 0.63), confirming satisfactory convergent validity for the DASH questionnaire. Satisfactory test-retest reliability (intraclass correlation coefficient 0.99, 95% confidence interval 0.98–0.99) and face validity of the questionnaire were confirmed.
The DASH questionnaire showed satisfactory test-retest reliability, concurrent-, convergent-, and face validity for patients with rheumatoid arthritis and can be recommended for use in rheumatoid arthritis populations.
本研究旨在评估残疾上肢、肩和手（DASH）问卷在瑞典类风湿关节炎人群中的信度和效度。
为了评估同时效度和聚合效度，67 例类风湿关节炎患者完成了 DASH、健康评估问卷残疾指数（HAQ）和活动诱发疼痛的评估。主动肩臂运动、手握力和疾病活动（28 个关节疾病活动评分；DAS28）也进行了评估。26 例患者进行了测试-重测信度评估。还进行了表面效度的评估。
Spearman 相关系数显示 DASH 评分与 HAQ 指数之间存在显著相关性（p < 0.001）（rs 0.80），证实了满意的同时效度。DASH 评分与主动肩臂运动（rs –0.38 至 –0.50）、手握力（rs –0.46 至 –0.59）、活动诱发疼痛（rs 0.66）和 DAS28（rs 0.63）之间存在显著相关性，证实了 DASH 问卷具有满意的聚合效度。该问卷具有满意的测试-重测信度（组内相关系数 0.99，95%置信区间 0.98-0.99）和表面效度。
DASH 问卷在类风湿关节炎患者中具有满意的测试-重测信度、同时效度、聚合效度和表面效度，可推荐用于类风湿关节炎人群。
