Brazilian-Portuguese translation, cross-cultural adaptation and validation of the Myasthenia Gravis Composite scale. A multicentric study

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.

Translation into Portuguese, adaptation, and validity assessment of the food safety climate self‐assessment tool

“…Kappa for the intensity of agreement and Pearson's correlations among the 28 items for the English and Portuguese versions according to the assessment of seven experts considering the high level of expertise of the translators, teachers, and experts in this field of research.The utilization of Cohen's kappa coefficients and Pearson's correlation demonstrated that the intensity of agreement was up to 80%, indicating a significant concordance between the two versions. These indices have been used widely in previous studies that developed versions of scales in different languages(de Vilhena, Duarte, & Lopes, 2016;Odunaiya, Louw, & Grimmer, 2017;Oliveira et al, 2016;Yilmaz, Gafuroglu, Ryall, & Yuksel, 2018). In the present study, satisfactory kappa scores were obtained (>0.70; p > .05).…”

Quantitative Myasthenia Gravis Score: a Brazilian multicenter study for translation, cultural adaptation and validation

“…The concurrent validity of the Brazilian Portuguese version of the QMGS was evaluated against the Portuguese version of the Myasthenia Gravis Composite Scale (MGC) 17 and the Portuguese version of the 15-item Myasthenia-specific Quality of Life Questionnaire (MG-QOL 15) 18 in a group of 30 patients with MG. The same evaluator applied the MGC and QMGS.…”

“…The authors developed this study searching papers in the Web of Science and Scopus. The artisanal fisheries, was the object of the investigation conducted by Oliveira et al, (2016) demonstrate the growth in this area, following the other areas previously mentioned. The researchers observed an interesting data, the brazilian authors they do not relate to researchers from the other countries, although they occupy the second place in number of publications in this field, where the USA leads the researches in quantity.…”

“…Studies in the field of food technology and nutrition, demonstrate that this is a field of science of growing interest by researchers (VAN RAAN; VAN LEEUWEN, 2002;ALFARAZ;CALVINO, 2004;PICCOLO et al, 2014;TAO et al, 2015), but the exponential growing is not observed in studies about food like in seafood quality. Seafood fisheries (OLIVEIRA et al, 2016) have linear growing, aquaculture too (NATALE et al, 2012;GUO et al, 2016), therefore, in addition to the fact that there are no bibliometric studies on seafood quality, this field is even more interesting because it presents exponential growth.…”
