Translation and adaptation of the Auditory processing domains questionnaire into Brazilian portuguese

Purpose to translate and adapt the Auditory Processing Domains QuestionnairetoBrazilian Portuguese. Methods this descriptive, exploratory, multicenter study translated and adapted the questionnaire in six stages: 1) translation by two bilingual Brazilian speech-language-hearing pathologists; 2) back-translation by an American English teacher and another bilingual speech-language-hearing pathologist, neither involved in the previous stage; 3) review and reduction, in which the researchers compared the 52-item with the current 50-item questionnaire; 4) expert committee with professionals in the field; 5) non-expert committee with the children’s and adolescents’ parents/guardians; 6) pilot study with a small sample with the characteristics of the instrument’s target population. Results the questions were carefully translated into the target language, with minimal changes that did not affect their content. Back-translation confirmed the accuracy without disparities in relation to the original version. The questionnaire review excluded two questions and modified 21 questions. The expert committee (nine speech-language-hearing pathologists with doctoral degrees) and the non-expert committee (30 parents/guardians) agreed on the formulation and understandability of the 50 questions. The pilot study applied the questionnaire to 30 participants, divided into a control group, a human communication disorder group, and an attention-deficit/hyperactivity disorder group. Conclusion the translation ensured the cultural equivalence of the Auditory Processing Domains Questionnaire in Brazilian Portuguese.
