[Validation of the combined SF36/MSQOL test of evaluation of quality of life in migraine patients in France].

The impact of migraine on patients quality of life is great, even between attacks. The aim of this study was to assess the properties of a French language quality of life questionnaire, which associates the Medical Outcome Study Short Form (MOS SF 36) with the Migraine-Specific Quality of Life (MSQOL). Data were obtained from 110 consultant patients of neurology units located in three University hospitals in the center of France. The results indicated a good acceptability of the association of the two questionnaires with a 84p.cent response rate. The Principal Component Analysis showed no change in both SF-36 and MSQOL structures. It also suggested that the two questionnaires were complementary. The high values of the Cronbach alpha coefficients for each scale indicated a high level of internal consistency. The quality of life scores were correlated with external parameters such as frequency, intensity and length of migraine attacks, and social activity reduction due to these attacks. In conclusion, the association of the SF-36 with the MSQOL has the interest of associating generic and specific questionnaire, in a complementary way. This association has good psychometric properties, and can be used to evaluate migraineurs quality of life in French speaking countries.
