Abstract
- <bold>Introduction: </bold>We sought to translate, cross-culturally adapt, and evaluate the internal consistency and validity of the Chinese version of the 15-Item Myasthenia Gravis Quality of Life (MG-QOL15).<bold>Methods: </bold>Translation and cross-cultural adaptation of the MG-QOL15 were performed. We used Cronbach's α to test internal consistency, one-way analysis of variance to test construct validity, and Pearson or Spearman correlations to test discriminant and concurrent validity.<bold>Results: </bold>We enrolled 168 outpatients. Internal consistency was excellent (Cronbach's α = 0.928). The MG-QOL15 discriminated MG severity as stratified by the MG Composite (MGC; P < 0.001) and Osserman class (P = 0.01). Concurrent validity was low to moderate with the subscales of the 36-item Short Form (-0.31 to ∼-0.59), MGC (r = 0.46), and Myasthenia Gravis Activities of Daily Living profile (r = 0.54).<bold>Discussion: </bold>The Chinese MG-QOL15 showed comparable construct, discriminant and concurrent validity, and internal consistency with to the original version.
