Validation of the Spanish version of the migraine disability assessment questionnaire (MIDAS) in university students with migraine

Abstract

Background: The Migraine Disability Assessment (MIDAS) questionnaire is widely used to determine the degree of migraine-related disability of subjects. So far, and to the best of our knowledge, no Spanish version of this tool has been validated. The questionnaire comprises seven items, with the first five constituting the main scale while the sixth and seventh items referring, respectively, to the frequency and intensity of headache. The present study aims to analyze 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 for this measuring instrument. A total of 153 subjects participated in the study. We analyzed construct validity using 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 revealed a two-factor structure. The questionnaire has good reliability for the MIDAS mainscale 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 moderately good reliability for headache intensity (ICC = 0.63; 95% CI: [0.34-0.80]). The analysis also yielded good internal consistency results (α Cronbach = 0.797) and a moderate correlation between MIDAS-main scale and the physical component summary 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 migrainerelated disability in university subjects. The two additional items provide information that could help clinicians in making decisions.

Thai-version Migraine Disability Assessment (MIDAS) questionnaire: concurrent validity, test–retest reliability, internal consistency, and factors predictive for migraine-related disability

“…There have been 9 non-English versions of the MIDAS questionnaire, with Italian [31], Japanese [32], Turkish [33,34], Taiwanese [35], Thai [27,28], Arabic [36], Greek [37], German [38], and Spanish [39] versions that have been previously reported ( Table 7). The development process for a non-English version from an original English version questionnaire included forward and backward translation.…”

“…"On a scale of 0 to 10, on average how painful were these headaches? (where 0 = no pain at all, and 10 = pain as bad as it can be)" undergraduate and graduate students diagnosed as having migraine [39]. For other versions with one translator for each process, or without mentioning the process, the Japanese version was tested for criterion validity with diary-based measures with a correlation coefficient of 0.36-0.66 for the 5 questions individual and of 0.66 for MIDAS total score and test-retest reliability with Spearman correlation coefficients of 0.59-0.80 for the 5 individual questions and of 0.83 for MIDAS total score in 99 people with headache, and just more than half of them (50.5%) were diagnosed with migraine at a neurological department and an affiliated clinic [32].…”

“…The other Thai version was assessed for test-retest reliability with correlation coefficients ranging from 0.36 to 0.94 and for internal consistency with an ICC of 0.95 [28]. Among all of the non-English versions, 6 versions were tested for validity, internal consistency, and test-retest reliability [33][34][35][36][37]39]. Only 2 Turkish versions [33,34], had moderateto-strong validity (Spearman correlation coefficients of 0.40-0.59 considered moderate, and 0.60-0.79 considered strong) and had strong-to-very strong test-retest reliability, but both were in between acceptable and unacceptable for internal consistency (Cronbach α across 0.8).…”

“…The sum of the score of the first five items provides the degree of headache-related disability while the sixth and seventh items indicate the frequency and intensity of migraine, respectively. This questionnaire presented excellent reliability values for the main scale (ICC = 0.81; 95% CI = 0.63-0.90; p < 0.001) and for headache frequency (ICC = 0.90; 95% CI = 0.79-0.95; p < 0.001), and good results for headache intensity (ICC = 0.63; 95% CI = 0.34-0.80; p < 0.001) as well as good internal consistency results (Cronbach's alpha = 0.797) [19].…”

“…The presence/absence of a migraine was determined through the medical diagnosis made at the beginning of the study. The degree of migraine-related disability as a way to estimate the personal impact of a migraine in terms of lost useful time as well as the frequency and intensity of a migraine, two of the most important criteria for a headache diagnosis, were estimated through the Spanish version of the Migraine Disability Assessment questionnaire [19]. Seven items compose this instrument: the first five items focus on three dimensions of daily life that can be affected by headaches while the other two items refer to the frequency and intensity of headaches.…”
