ABSTRACT Introduction We translated the myasthenia gravis (MG)‐specific activities of daily living (MG‐ADL) scale into Arabic (MG‐ADL‐A) and assessed its psychometric properties. Methods We assessed reliability using Cronbach's α, reproducibility using the intraclass correlation coefficient, and validity using Spearman's correlations with MG composite (MGC) score, MG‐specific manual muscle test (MG‐MMT), and MG quality‐of‐life revised Arabic version (MGQOL15R‐A). Differences in MG‐ADL‐A scores among patients with different disease severity were evaluated by using the Kruskal–Wallis test. Sensitivity to change was examined by using the Wilcoxon signed‐rank test. Results We recruited 87 patients. The mean MG‐ADL‐A score was 3.38 ± 3.38 (α = 0.77, ICC = 0.99). The correlation coefficients between the MG‐ADL‐A and MGQOL15R‐A, MGC, and MG‐MMT were 0.63, 0.74, and 0.61, respectively ( P < 0.001). The MG‐ADL‐A discriminated between different severity groups and was responsive to clinical improvement at follow‐up. Discussion The MG‐ADL‐A has rigorous psychometric properties and can be used with Arabic‐speaking patients with MG. Muscle Nerve 59:583–583, 2019
