Abstract

Background: The 8-item myasthenia gravis activity of daily living (MG-ADL) questionnaire is a valid and reliable instrument for evaluating myasthenia gravis (MG)-associated disability. This study aims to assess its validity and reliability in the Iranian population. Methods: A total number of 58 patients with MG were qualified for the examination. All 58 patients completed the Persian translation of 15-item Myasthenia Gravis Quality of Life (MG-QOL15) and MG-ADL questionnaires initially, and 30 filled out the MG-ADL questionnaire 2 to 4 weeks after the initial visit. Pearson correlation coefficient of questionnaires, internal consistency using Cronbach's alpha (α), and test-retest repeatability of the questionnaire were evaluated. Results: The Pearson correlation coefficient of Persian versions of MG-QOL and MG-ADL was 0.93 (P < 0.01). The Persian MG-ADL showed satisfactory internal consistency (Cronbach's α = 0.89) and test-retest reliability (r = 0.99, P < 0.01). Conclusion: The Persian MG-ADL is a valid and reliable questionnaire for the determination of activities of daily life in Iranian patients with MG.

重症肌无力日常生活活动问卷的验证：波斯语版

背景：8项重症肌无力日常生活活动量表（MG-ADL）是评估重症肌无力（MG）相关残疾的有效和可靠的工具。本研究旨在评估其在伊朗人群中的有效性和可靠性。方法：对58例MG患者进行检查。所有58名患者最初完成了15项重症肌无力生活质量（MG-QOL15）和MG-ADL问卷的波斯语翻译，30名患者在首次就诊后2-4周填写了MG-ADL调查表。评估问卷的Pearson相关系数、使用Cronbachα（α）的内部一致性以及问卷的重测可重复性。结果：波斯版MG-QOL和MG-ADL的Pearson相关系数为0.93（P<0.01），波斯版MG-ADL具有良好的内部一致性（Cronbachα=0.89）和重测信度（r=0.99，P<0.01）。
