The Myasthenia Gravis—Activities of Daily Living (MG‐ADL) profile scale is a simple‐to‐use instrument. We aimed to validate this scale in the Korean language and compare physician‐ and self‐assessed MG‐ADL scores (pMG‐ADL‐K and sMG‐ADL‐K). Methods pMG‐ADL‐K and sMG‐ADL‐K and MG Composite (MGC) scores were obtained from patients. The correlation between pMG‐ADL‐K and MGC and the relationship between the pMG‐ADL‐K and sMG‐ADL‐K were assessed using the Cronbach α and the Spearman coefficient. By intraclass correlation coefficient (ICC), the reliability of each sub‐item of pMG‐ADL‐K and sMG‐ADL‐K was evaluated. Results We included data from 40 patients. The pMG‐ADL‐K score showed a strong correlation with the MGC score (rho = 0.80, P < 0.01). The Cronbach α was 0.98 between pMG‐ADL‐K and sMG‐ADL‐K, and sub‐items showed good consistency (ICC 0.684–0.985, P < 0.001). Discussion The MG‐ADL‐K is a valid tool and the sMG‐ADL‐K shows excellent correlation with pMG‐ADL‐K. Both the pMG‐ADL‐K and sMG‐ADL‐K can be used to measure MG severity.
