Abstract
Introduction: 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.
