MIDAS问卷是为了评估头痛相关的残疾而开发的，目的是改善偏头痛的护理。头痛患者回答五个问题，对过去3个月中因偏头痛而限制活动的天数进行评分。该问卷的内部一致性、重测信度和有效性(准确性)是在对偏头痛患者进行的单独的人群研究中进行评估的。此外，在一组49名医生中对问卷的表面有效性、易用性和临床效用进行了评估，这些医生在不同的偏头痛病历样本中独立评估了疾病的严重性和护理需求。MIDAS总分的重测皮尔逊相关系数约为0.8。与基于参考日记的残疾测量相比，MIDAS评分是有效的；MIDAS和基于日记的测量之间的总体相关性为0.63。MIDAS评分也与医生对医疗保健需求的评估相关(r=0.69)。从迄今完成的研究来看，MIDAS问卷已被证明是内部一致的、高度可靠的、有效的，并与医生的临床判断相关。这些特点支持了它在临床实践中的适用性。MIDAS问卷的使用可能会改善医患之间关于头痛相关残疾的沟通，并可能有利地影响偏头痛患者的医疗保健提供。
The MIDAS Questionnaire was developed to assess headache-related disability with the aim of improving migraine care. Headache sufferers answer five questions, scoring the number of days, in the past 3 months, of activity limitations due to migraine. The internal consistency, test-retest reliability, and validity (accuracy) of the questionnaire were assessed in separate population-based studies of migraine sufferers. In addition, the face validity, ease of use, and clinical utility of the questionnaire were evaluated in a group of 49 physicians who independently rated disease severity and need for care in a diverse sample of migraine case histories. The test-retest Pearson correlation coefficient for the total MIDAS score was approximately 0.8. The MIDAS score was valid when compared with a reference diary-based measure of disability; the overall correlation between MIDAS and the diary-based measure was 0.63. The MIDAS score was also correlated with physicians' assessments of need for medical care (r = 0.69). From studies completed to date, the MIDAS Questionnaire has been shown to be internally consistent, highly reliable, valid, and correlates with physicians' clinical-judgment. These features support its suitability for use in clinical practice. Use of the MIDAS Questionnaire may improve physician-patient communication about headache-related disability and may favorably influence health-care delivery for migraine patients.
