ABSTRACT

ABSTRACT Objective To perform the translation, cultural adaptation and validation of the Myasthenia Gravis Composite (MGC) scale in Brazil. Methods The study was conducted at three neuromuscular disease research centers in accordance with the international ethical standards, following a multi-modal approach and was conducted in three steps consisting of translation, cultural adaptation, and validation according to international guidelines. The final version of the MGC was applied in a sample of 27 MG patients and the total score was compared to a Portuguese version of the MG-QOL-15. Results The internal consistency verified by Cohen’s Kappa test was excellent (0.766). The correlation between the MGC and MG-QOL-15 was strong (R = 0.777; p = 0.000). No significant differences were found between the responses of patients in the first and second applications of the MGC. Conclusion The MGC scale, validated into Brazilian Portuguese, has proven to be a reliable instrument that is easy to use, and is highly reproducible.


RESUMO Objetivo Realizar a tradução e a adaptação transcultural da escala composta de Miastenia Grave (ECMG) Myasthenia Gravis Composite (MGC) no Brasil. Métodos O estudo foi realizado em três centros de investigação em doenças neuromusculares, de acordo com as normas éticas internacionais, consistindo em tradução, adaptação cultural e validação de acordo com as diretrizes internacionais. A versão final do MGC ECMG foi aplicada em vinte e sete pacientes com MG e a pontuação total foi comparada ao questionário MG-QOL 15. Resultados A consistência interna verificada pelo teste Kappa de Cohen foi excelente (0,766) e a correlação entre o a ECMG MGC e MG-QOL 15 foi positiva (R = 0,777; p = 0,000). Não foram encontradas diferenças entre as respostas dos pacientes na primeira e segunda aplicação da MGC. Conclusão A ECMG escala MGC validada para o Português do Brasil provou ser um instrumento confiável, de fácil aplicação e altamente reprodutível.
