Methods The following steps were taken: (1) implementation of the translation protocol and transcultural adaptation, (2) validation of the adapted content, and (3) assessment of reliability. To check intra- and inter-observer reproducibility, each patient underwent two interviews with interviewer-A and one with B. The QMGS was compared to the Myasthenia Gravis Composite Scale and Myasthenia-specific Quality of Life Questionnaire. Results Our study group consisted of 30 patients, with a mean age of 47.6\u00b111.4 years and a mean duration of illness of 11.33\u00b18.49 years. Correlation between the QMGS and MGC was very strong (r = 0.928; p &lt; 0.001) and substantial between the QMGS and MG-QOL 15 (r = 0.737; p &lt; 0.001). Conclusion The Brazilian Portuguese translation, and validation of the QMGS was successfully performed.<\/jats:p>","DOI":"10.1590\/0004-282x20170075","type":"journal-article","created":{"date-parts":[[2017,7,19]],"date-time":"2017-07-19T18:19:10Z","timestamp":1500488350000},"page":"457-463","source":"Crossref","is-referenced-by-count":5,"title":["Quantitative
