[Quality of life and migraine. Validation of the QVM questionnaire in hospital consultation and in general medicine].

The feasibility, the validity and reliability of the questionnaire "Qualité de Vie et Migraine" (QVM) were assessed during a study performed on 107 patients recruited either in neurological departments in hospitals (N = 58) or by G.P. (N = 49). The study was designed as a Test-Retest, the self-questionnaire being filled twice at an interval of one week. The filling-in time was an average 7 min in hospital and 11 min for G.P.'s patients. The missing values were quite rare, between 1% and 2%. The items were assessed "very interesting" or "interesting" by 94% of the patients, and "easy" or "fairly easy to understand" by 96%. The principal component analysis performed on the whole sample allowed the extraction of 4 meaningful factors which were in agreement with the pre-defined structure of the questionnaire QVM. The 1st axis was a factor of psychological repercussion, the 2nd axis was a factor of functional and somatic repercussion, the 3rd axis was a factor of social repercussion and the 4th one was a factor of disturbance generated by the treatment. The QVM questionnaire allowed the calculation of a global index of quality of life and indexes according to the multifactorial structure. The global index was significantly higher for the most severe patients recruited in hospital, which means that the repercussion of migraine on quality of life was greater than for G.P.'s patients.(ABSTRACT TRUNCATED AT 250 WORDS)
