The Migraine Disability Assessment (MIDAS) questionnaire: translation and reliability of the Italian version.
We have developed and tested an Italian version of the Migraine Disability Assessment (MIDAS) questionnaire, an established instrument for assessing headache-related disability. A multistep process was used to translate and adapt the questionnaire into Italian, which was then tested on 109 Italian migraine without aura patients, 86 (78.9%) of whom completed the form a second time 21 days later. Overall MIDAS score had good test-retest reliability (Spearman's correlation 0.77), closely similar to that found in English-speaking migraineurs, and individual responses were also satisfactorily reliable. Internal consistency was good (Cronbach's alpha 0.7). These findings support the use of the MIDAS questionnaire as a clinical and research tool with Italian patients.
