Abstract
in English, Portuguese

Objective: To translate the King's Brief Interstitial Lung Disease (K-BILD) questionnaire to Portuguese and culturally adapt it for use in Brazil. The K-BILD quantifies the health status of patients with ILD.

Methods: The process involved the following steps: authorization from the author of the original (English-language) questionnaire; translation of the questionnaire to Portuguese by three translators, working independently; merging of the translations by a committee of specialists; back-translation of the questionnaire to English; revision and readjustment of the back-translation by the committee of specialists; evaluation by the original author; revision of the back-translation; cognitive debriefing (verification of the clarity and acceptability of the Portuguese-language version in the target population-i.e., patients with ILD); and finalization of the Portuguese-language version.

Results: In the cognitive debriefing step, 20 patients with ILD were interviewed. After the interviews, the clarity and acceptability index of each question was ≥ 0.8, which is considered acceptable.

Conclusions: The Portuguese-language version of K-BILD appears to be easily administered to and understood by patients with ILD in Brazil. To our knowledge, this is the only instrument in Brazilian Portuguese that is designed to evaluate the impact that ILD has on the various aspects of the lives of those it affects.

Objetivo:: Traduzir e adaptar culturalmente o King’s Brief Interstitial Lung Disease (K-BILD) health status questionnaire, utilizado para mensurar o estado de saúde em pacientes com doença pulmonar intersticial (DPI), para a língua portuguesa falada no Brasil.

Métodos:: As seguintes etapas foram realizadas: autorização do autor do instrumento original; preparação; tradução do K-BILD da língua inglesa para a língua portuguesa falada no Brasil por três tradutores independentes; unificação das traduções por um comitê de especialistas; retradução do português para o inglês; revisão e readequação da retradução pelo comitê de especialistas; avaliação do autor do original; revisão da versão em inglês; desdobramento cognitivo (observação da clareza e aceitabilidade do questionário traduzido na população-alvo); e elaboração da versão final em português.

Resultados:: Na etapa de desdobramento cognitivo foram entrevistados 20 pacientes com DPI. Após todas as entrevistas, o índice de clareza e aceitabilidade das questões foi igual ou maior que 0,8, indicando um índice de clareza aceitável para todas as questões.

Conclusões:: A versão do K-BILD mostrou ser compreensível e de fácil aplicação. Até onde sabemos, esse é atualmente o único instrumento disponível em português falado no Brasil dirigido à avaliação do impacto da DPI em vários aspectos da vida desses pacientes.
