Abstract:
Objective:To translate Myasthenia Gravis-Activities of Daily Living Scale (MG-ADL) into Chinese and test its reliability and validity in patients with myasthenia gravis (MG) .Methods:According to the cross-cultural adaptation guidelines of the self-report scale, the Chinese version of the MG-ADL was completed through cross-cultural adaptation steps such as pre-translation, integration, back-translation, expert committee evaluation and pre-survey. A total of 150 MG patients hospitalized in Department of Neurology and Thoracic Surgery of Beijing Tongren Hospital Affiliated to Capital Medical University from November 2021 to August 2022 were selected as research objects by the convenient sampling method to test the reliability and validity of the Chinese version of MG-ADL. A total of 150 questionnaires were sent out in this study and 135 were effectively received, with the effective recovery of 90.00%.Results:The content validity index at the level of each item of the Chinese MG-ADL was 0.857-1.000, and the average content validity index at the level of the scale was 0.982. MG quantitative score scale was used as the criterion, and the criterion validity was 0.807 ( P<0.01) . The Cronbach's α coefficient of MG-ADL was 0.645. The retest reliability coefficient was 0.959. The evaluation time of MG-ADL was (4.69±1.79) min, and the minimum clinically significant difference was 1.82. Conclusions:The Chinese version of MG-ADL has good validity, reliability and operability, and it can be used as a specific assessment tool to evaluate the activity of daily living of MG patients.
