ABSTRACT

Objective: To translate the Knowledge of, Attitude towards, and Preventive Behavior towards Tuberculosis questionnaire into Brazilian Portuguese and adapt it for use in Brazil. Methods: This methodological study followed internationally recommended guidelines for translation and cross-cultural adaptation. After permission was obtained from the original authors, the process of translation and cross-cultural adaptation began, including translation into Brazilian Portuguese by bilingual translators, synthesis of the translations, back-translation for similarity analysis, revision, and preparation of the final version. A pretest was conducted on 68 medical students. Results: Most of the questionnaire items showed strong content similarity, with minor semantic differences. The content validity index for the questionnaire was 0.882, and Cronbach's alpha coefficients were 0.682, 0.809, and 0.613 for knowledge of tuberculosis, attitudes toward tuberculosis, and preventive behavior toward tuberculosis, respectively. Cronbach's alpha and omega coefficients were a = 0.717, ?1 = 0.673, ?2 = 0.673, and ?3 = 0.520. Conclusions: The process of translation and cross-cultural adaptation of the Knowledge of, Attitude towards, and Preventive Behavior towards Tuberculosis questionnaire was successful, making the Brazilian Portuguese version of the questionnaire reliable for reproducibility. It can be used in order to collect tuberculosis-related data and support changes in health education curricula.
