Cross-cultural adaptation to Brazilian Portuguese of the Michigan Neuropathy Screening Instrument: MNSI-Brazil.

Since 1994, the University of Michigan Diabetes Research and Training Center proposed an instrument to measure neuropathies not yet adapted to use in Brazil. Then, this study aimed to adapt cross-culturally the Michigan Neuropathy Screening Instrument (MNSI) into Brazilian Portuguese, verifying its reliability. Thirty diabetic patients were initially evaluated with the adapted version after completed the essential steps to accomplish the cross-cultural adaptation. Twenty-two of them completed the procedures to repeat the measured scores after day 1 (trial 0). The repeated measurements were tested at days 2 or 3 (trial 1) by another rater (inter-rater reliability) and retested at day 20 (trial 2) by one of the attended raters (inter-test reliability). There were not great semantics, linguistics or cultural differences between two versions and excellent reliability was confirmed by intra-class correlation coefficient above 0.840. It was concluded that MNSI in the Brazilian version is reliable and it is ready to use.

RESUMO Desde 1994, o Centro de Treinamento e Pesquisa em Diabetes da Universidade de Michigan propôs um instrumento não ainda adaptado para uso no Brasil para mensurar neuropatias. O objetivo deste estudo foi adaptar transculturalmente o Michigan Neuropathy Screening Instrument (MNSI) para o Português brasileiro, verificando sua confiabilidade. Trinta pacientes diabéticos foram inicialmente avaliados pela versão adaptada depois de completados os passos essenciais para finalizar a adaptação transcultural. Vinte e dois deles completaram os procedimentos para repetir os escores medidos depois do dia 1 (ensaio 0). As medidas repetidas foram testadas nos dias 2 ou 3 (ensaio 1) por outro examinador (confiabilidade interexaminador) e retestadas no dia 20 (ensaio 2) por um dos examinadores participantes (confiabilidade interteste). Não existiam diferenças semânticas, linguísticas ou culturais entre as duas versões e excelente confiabilidade foi confirmada pelo coeficiente de correlação intra-classe acima de 0,840. Conclui-se que o MNSI na versão brasileira é confiável e está pronto para uso.
