INTRODUCTION: Evaluation of quality of life (QOL) has become essential in healthcare. Currently no MG-specific QOL measure exists in French. The aim of this study was to translate, culturally adapt, and evaluate the psychometric properties of the French version of the 15-Item Myasthenia Gravis Quality of Life Scale (MG-QOL15) scale for French myasthenia patients.
METHODS: Translation and cross-cultural adaption of the MG-QOL15 was performed, followed by reliability and validity evaluations.
RESULTS: One hundred and twenty-five patients were included. Internal consistency was excellent (Cronbach α = 0.92) as was test-retest reliability (ICC = 0.92, 95% CI 0.86-0.96). Concurrent validity was good for both clinical scores (myasthenic muscle score: ρ = -0.52, P < 0.001; Myasthenia Gravis-Activities of Daily Living scale score: ρ = 0.62, P < 0.001). Correlations were strongest for overall QOL (ρ = 0.62, P < 0.001) and physical health (ρ = 0.67, P < 0.001) on the World Health Organization Quality of Life short score (WHO-QOL BREF).
CONCLUSION: The French version of the MG-QOL15 is valid and reliable and is now available for use with French-speaking patients. Muscle Nerve, 2016 Muscle Nerve 55: 639-645, 2017.
