ABSTRACT
OBJETIVO: Realizar a tradução e a adaptação cultural do questionário WORC (The Western Ontario Rotator Cuff Index) para a língua portuguesa para ulterior validação no Brasil. MÉTODOS: O protocolo aplicado consistiu em: 1) Preparação, 2) Tradução, 3) Tradução de volta à língua original (retro-tradução), 4) Interrogatório Cognitivo e 5) Relato de Informações. Ao serem concluídas as etapas de tradução e retro-tradução, as versões foram enviadas para os autores do WORC original, que as aprovaram para continuação do estudo. A versão em Português foi aplicada a 35 pacientes com disfunções do manguito rotador para verificar o nível de compreensão do instrumento. A idade média foi 57 anos (DP=13), 63 por cento eram do sexo feminino e 74 por cento tinham nível de escolaridade de primeiro grau incompleto. A versão brasileira final do WORC foi definida após se conseguir menos que 15 por cento de "não compreensão" em cada item. Para análise das variáveis, foi utilizada estatística descritiva. RESULTADOS: Realizaram-se mudanças e substituições de termos e expressões para obter equivalência cultural do WORC. Alteraram-se também os termos "não compreendidos" pelos pacientes de acordo com as sugestões feitas por eles. CONCLUSÃO: Após a tradução e adaptação cultural do questionário, foi concluída a versão em Português do WORC que está em processo de validação para ser utilizada no Brasil.
OBJECTIVE: To accomplish the translation of WORC (The Western Ontario Rotator Cuff Index) into Portuguese and its cultural adaptation, for future validation in Brazil. METHOD: The protocol applied consisted of: 1) Preparation; 2) Forward translation; 3) Back translation; 4) Cognitive Debriefing; and 5) Information report. After concluding the forward and back-translations, the versions were sent to the authors of the original questionnaire, who gave their approval for the study to be continued. The Portuguese version was applied to 35 patients with rotator cuff dysfunctions to verify the level of understanding of the instrument. The mean age of these patients was 57 years (SD = 13); 63 percent were female and 74 percent had not completed elementary school. The final Brazilian version of WORC was defined after achieving a "no comprehension" rate of less than 15 percent for each item. Descriptive statistics were used to analyze the variables. RESULTS: Some terms and expressions were changed or replaced to obtain cultural equivalence for WORC. The terms that were incomprehensible to the patients were changed in accordance with their own suggestions. CONCLUSION: After the translation and cultural adaptation of the questionnaire, the final Portuguese version of WORC was concluded and it is now undergoing validation for use in Brazil.

The objective of the present study was to translate the Kidney Disease Quality of Life - Short Form (KDQOL-SFÕ1.3) questionnaire into Portuguese to adapt it culturally and validate it for the Brazilian population. The KDQOL-SF was translated into Portuguese and back-translated twice into English. Patient difficulties in understanding the questionnaire were evaluated by a panel of experts and solved. Measurement properties such as reliability and validity were determined by applying the questionnaire to 94 end-stage renal disease patients on chronic dialysis. The Nottingham Health Profile Questionnaire, the Karnofsky Performance Scale and the Kidney Disease Questionnaire were administered to test validity. Some activities included in the original instrument were considered to be incompatible with the activities usually performed by the Brazilian population and were replaced. The mean scores for the 19 components of the KDQOL-SF questionnaire in Portuguese ranged from 22 to 91. The components "Social support" and "Dialysis staff encouragement" had the highest scores (86.7 and 90.8, respectively). The test-retest reliability and the inter-observer reliability of the instrument were evaluated by the intraclass correlation coefficient. The coefficients for both reliability tests were statistically significant for all scales of the KDQOL-SF (P < 0.001), ranging from 0.492 to 0.936 for test-retest reliability and from 0.337 to 0.994 for inter-observer reliability. The Cronbach's alpha coefficient was higher than 0.80 for most of components. The Portuguese version of the KDQOL-SF questionnaire proved to be valid and reliable for the evaluation of quality of life of Brazilian patients with end-stage renal disease on chronic dialysis.
