OBJECTIVES: The aim of this study is to evaluate the comprehensibility, internalconsistency, patient-physician reliability, and test-retest reliability of the Thai version ofMigraine Disability Assessment (Thai-MIDAS) questionnaire in Thai migraine sufferers.

MATERIAL AND METHODS: Study participants were recruited from patients diagnosedwith migraine headache according to International Classification of Headache Disordersversion 2 (ICHD-2) criteria who attended the Headache Clinic at Bangkok Hospitalheadquarters. Standard forward and backward translation procedures were used totranslate the MIDAS questionnaire into the Thai-MIDAS version. Patients completedthe Thai-MIDAS questionnaire at baseline (visit 1), after meeting the physician (visit 2),and at the two-week follow up (visit 3) to assess disease severity and comprehensibility,internal consistency, as well as test-retest reliability.

RESULTS: A total of 82 patients, aged between 15 and 54 years were enrolled in thestudy (71 females and 11 males). At baseline, most of the patients had severe migrainedisability (MIDAS grade IV) and severe pain score. All 5 items of the Thai-MIDASquestionnaire demonstrated excellent internal consistency (ICC 0.95; 95% CI 0.91-0.99).The total Thai-MIDAS score showed good test-retest reliability by Pearson correlationcoefficient (r = 0.81; 95% CI 0.69-0.88, p = 0.05).

CONCLUSION: These findings demonstrated that the Thai translation of MIDAS isequivalent to the English version of MIDAS in terms of internal consistency andtest-retest reliability. Physicians can reliably use the self-administered tool, the Thai-MIDAS questionnaire, to assess the severity and disability of migraine in Thai patients.
