EHMTI-0063. The migraine disability assessment (MIDAS) questionnaire: translation, validation and reliability of Bahasa Melayu version

Background: Better understanding of migraine treatment in US clinical practice could be facilitated by availability of Migraine Disability Assessment (MIDAS) questionnaire results collected in routine care. We present results for migraine patients with MIDAS collected in routine clinical practice through an electronic medical record (EMR) system that presented the MIDAS questionnaire as an electronic form during the patient office encounter. The purpose of this retrospective observational study was to gain better understanding of migraine disability and migraine treatment patterns in US real-world clinical practice. Methods: In this EMR database study, patients were required to have 12 months baseline time for review of patient and clinical characteristics. Adult patients with documentation of migraine with subsequent MIDAS questionnaire data collected between March 2017 and September 2018 were included. Based on MIDAS responses patients were categorized into grade I—little or no disability, grade II—mild disability, grade III—moderate disability, and grade IV—severe disability. Results: This study included 2731 migraine patients with MIDAS results. Overall, 2309 (84.5%) were female with an average age of 46.7 years. Distribution by disability grade was 1161 (42.5%) little or no disability, 424 (15.5%) mild disability, 477 (17.5%) moderate disability, and 669 (24.5%) severe disability. Compared to overall, a larger proportion of patients with severe disability had baseline treatment with acute (71.3% vs. 67.6%) or preventive medications (70.4% vs. 62.0%) and to be on 3+ acute (9.4% vs. 7.0%) or 3+ preventive therapies (17.0% vs. 14.5%). Conclusion: Availability of MIDAS results in usual care provides additional insight into migraine care.

Background. The Migraine Disability Assessment (MIDAS) score is used to quantify headache-related disability. In a previous study, we showed that the MIDAS score was highly reliable in population-based samples of migraine headache sufferers in two countries. Objectives. To examine the test–retest reliability and internal consistency of the five items comprising the MIDAS score and the overall MIDAS score in a population-based sample of both migraine and nonmigraine headache sufferers. Methods. Using a clinically validated telephone interview, a population-based sample of migraine and nonmigraine headache sufferers was identified in Baltimore, Maryland, USA. A total of 97 migraine cases and 80 nonmigraine subjects completed the MIDAS questionnaire on two occasions an average of 3 weeks apart. The MIDAS score is derived from five questions about missed time from work (or school) and household work (one question each about missed days and days with at least 50% reduced productivity) and missed days of nonwork activities. Results. Among all headache sufferers die test–retest Spearman's correlations of individual MIDAS questions ranged from 0.67 to 0.73. The Spearman's correlation for the MIDAS score (i.e., sum of lost days and reduced effectiveness days in each domain) was 0.84. Cronbach's alpha, a measure of internal consistency, was 0.83. Mean and median item values and the overall MIDAS scores differed between migraine and nonmigraine cases. Even after adjusting for differences in headache frequency, the mean MIDAS scores differed substantially (i.e., 10.3 points) between migraine cases and nonmigraine cases. Conclusions. The reliability and internal consistency of the MIDAS score are high, as tested in a population-based sample of headache sufferers. MIDAS scores are substantially higher in migraine cases than in nonmigraine cases, supporting the validity of the measure.

Midas Questionnaire

Abstract Background. The Migraine Disability Assessment (MIDAS) questionnaire is widely used for determining headache-related disability. However, to the best of our knowledge, there is no validated Spanish version of the questionnaire. It is composed of seven items; the first five items constitute the main scale, while the sixth and seventh items refer respectively to the frequency and intensity of headache. The present study is aimed at analyzing the clinimetric properties of the Spanish version of the MIDAS questionnaire in a population of university students.Methods. We performed a cross-sectional study of validation of measuring instruments. One hundred fifty-three subjects participated in the study. We analyzed construct validity by factor analysis, test-retest reliability by the Intraclass Correlation Coeficient (ICC), internal consistency, and concurrent validity with respect to the 12-Item Short Form Health Survey (SF-12).Results. Factor analysis showed a two factors structure composed. The questionnaire presented good reliability for the MIDAS-main scale score ([ICC = 0.81; 95% CI: 0.63 – 0.90]), excellent reliability for headache frequency (ICC = 0.90; 95%; CI: [0.79 – 0.95]), and moderate reliability for headache intensity (ICC = 0.63; 95% CI: [0.34 – 0.80]). The analysis also showed good internal consistency results (α Cronbach = 0.797) and a moderate correlation between MIDAS-main scale and physical summary component of SF-12 (Rho = -0.326; p < 0.001).Conclusions. The Spanish version of the MIDAS questionnaire is a valid and reliable tool to measure headache-related disability in university subjects. The two additional items provide information that could help clinicians in making decisions.
