Functional Assessment of Cancer Therapy-Brain questionnaire: translation and linguistic adaptation to Brazilian Portuguese

Abstract

CONTEXT AND OBJECTIVE: Quality of life assessment among patients with brain tumors is important, given that new treatments have increased patient survival. The aim of this study was to translate the Functional Assessment of Cancer Therapy-Brain (FACT-Br) questionnaire (version 4) into Portuguese, carry out cross-cultural adaptation and assess its reproducibility. DESIGN AND SETTING: Cohort at the Universidade Federal de São Paulo (Unifesp). METHODS: Forty patients with a brain tumor seen at the neuro-oncology outpatient clinic participated in the study. The process of translation and back-translation was carried out, along with adaptation to the Portuguese language and Brazilian culture. The intraclass correlation coefficient (ICC) was used to test the reproducibility of the FACT-Br (version 4). RESULTS:The reproducibility of the questionnaire was excellent (ICC = 0.95; 95% confidence interval, CI: 0.89-0.97). The ICC with a mean interval of 15 days between applications of the questionnaire was very good in all domains (ICC = 0.87 to 0.95). The mean time taken to answer the questionnaire was 6.27 ± 2.26 minutes, ranging from 3 to 11 minutes. CONCLUSION: The translated version of the FACT-Br questionnaire (version 4) adapted to the Portuguese language and Brazilian culture proved to be easily understood and achieved very good reproducibility among patients with diagnoses of brain tumors. reSUMO CONTEXTO E OBJETIVOS:A avaliação da qualidade de vida dos pacientes com tumor cerebral é importante, considerando que novos tratamentos têm aumentado sua sobrevida. O objetivo deste trabalho foi traduzir o questionário Functional Assessment of Cancer Therapy-Brain (FACT-Br) (versão 4) para a língua portuguesa, realizar a adaptação cultural e avaliar sua reprodutibilidade. DESIGN E LOCAL: Estudo de coorte realizado na Universidade Federal de São Paulo (Unifesp). MÉTODO: Quarenta pacientes com tumor cerebral provenientes do Ambulatório de Neuro-oncologia participaram do estudo. O processo de tradução inicial e retrógrada foi realizado, além da adaptação cultural para a língua e cultura brasileira. O coeficiente de correlação intraclasse (CCI) foi utilizado para testar a reprodutibilidade do FACT-Br (versão 4). RESULTADOS: A reprodutibilidade do questionário foi excelente (CCI = 0,95; intervalo de confiança, IC 95% 0,89-0,97). O CCI com intervalo médio de 15 dias entre aplicações do questionário, em todos os domínios, foi muito bom (CCI = 0,87 a 0,95). O tempo médio de resposta ao questionário foi de 6,27 minutos ± 2,26 minutos, variando de 3 minutos a 11 minutos. CONCLUSÃO: A tradução e a adaptação à língua e à cultura brasileira do questionário FACT-Br (versão 4) mostrou-se de fácil entendimento e com muito boa reprodutibilidade em pacientes com diagnóstico de tumor cerebral.I PT, PhD.

Translation and cultural adaptation of the stroke impact scale 2.0 (SIS): a quality-of-life scale for stroke

“…So far, the translation process was similar to that used for the translation of the Saint George Questionnaire for Respiratory Diseases, 12 Airways Questionnaire (AQ 20) 13 and functional assessment of cancer therapy-brain (FACT-BR). 14 In the fourth stage, the group responsible for the research compared the version translated into English with the original version in order to detect any friction relating to culture, thus generating a Portuguese version that would be applied to a sample of patients.…”
