Abstract
Purpose: To translate and cross-culturally adapt the Thyroidectomy-Related Voice Questionnaire (TVQ) to Brazilian Portuguese. Methods: We divided the process of translation and cross-cultural adaptation into the following stages: two independent translations; synthesis of the translations; analysis by an expert committee; pretest; back-translation; final synthesis; and final version. We performed the pretest with 20 patients before or after thyroidectomy. We characterized the sample by means of descriptive analysis, and calculated the agreement between the experts by the Item Content Validity Index (I-CVI) and the Questionnaire Content Validity Index (Q-CVI). Results: Throughout the translation and cross-cultural adaptation, the instrument required operational, semantic, idiomatic, and syntactic/grammatical equivalences, especially after the analyses by the experts and the target population. The I-CVI and Q-CVI were mostly acceptable. The back-translation was equivalent to the original version. The comparison between the original, translated, and back-translated versions made possible the final version. Conclusion: We translated and adapte

Resumo
Objetivo: Traduzir e adaptar o questionário Thyroidectomy-Related Voice Questionaire (TVQ) para o português brasileiro. Método: o processo de tradução e adaptação transcultural foi dividido nas seguintes etapas: duas traduções independentes, síntese das traduções, análise por um comitê de especialistas, pré-teste, retradução, síntese final e versão final. O pré-teste foi realizado com 20 pacientes que se encontravam no período pré ou pós-operatório de tireoidectomia. A amostra foi caracterizada por meio de análise descritiva, e a concordância entre os especialistas foi calculada pelo Índice de Validade de Conteúdo por Item (IVC-I) e do questionário (IVC-Q). Resultados: ao longo das etapas do processo de tradução e adaptação, o instrumento necessitou de equivalências do tipo operacional, semântica, idiomática e sintática/gramatical, especialmente após avaliação dos especialistas e da população-alvo. Os IVC-I e IVC-Q foram, em sua maioria, aceitáveis. A retradução mostrouse equivalente à versão original. A comparação entre as versões original, traduzida e retraduzida possibilitou a elaboração da versão final. Conclusão: o TVQ foi traduzido e adaptado para o português brasileiro, sendo considerado apto para as próximas etapas do processo de validação.
