ABSTRACT
INTRODUCTION:
The 15-item Myasthenia Gravis Quality Of Life (MG-QOL15) questionnaire is a valid and reliable instrument for evaluation of myasthenia gravis (MG) associated disability. Our study aim was to assess its validity and reliability in the Iranian population.METHODS:
We enrolled 75 consecutive patients with established MG at 2 neuromuscular clinics in Tehran, Iran. All 75 patients completed the Persian MG-QOL15 and SF-36 questionnaire initially, and 30 filled out the MG-QOL15 questionnaire from 2 to 4 weeks after the initial visit. Concurrent and construct validity, internal consistency, and test-retest repeatability of the questionnaire were evaluated.RESULTS:
The Persian MG-QOL15 showed satisfactory internal consistency (Cronbach alpha = 0.94) and test-retest reliability(r = 0.98; P < 0.001). It also demonstrated adequate concurrent and construct validity; moreover, the MG-QOL15 scores were higher in patients with more severe conditions.CONCLUSIONS:
The Persian MG-QOL15 is a valid and reliable questionnaire for determination of quality of life in Iranian MG patients. Muscle Nerve 54 65-70, 2016.Palavras-chave
