Tinnitus and hearing survey: cultural adaptation to Brazilian Portuguese

Abstract Introduction: Hearing loss is associated with several comorbidities and may be frequently associated with tinnitus. When patients complain of both tinnitus and hearing difficulties in audiology and otolaryngology clinics, there, is often great difficulty separating the two complaints. The tinnitus and hearing survey was specially developed for this purpose to identify the main complaint and help direct the choice of appropriate intervention. Objective: To translate and culturally adapt the tinnitus and hearing survey for the Brazilian-Portuguese. Methods: Seventy patients who had previously completed a battery of audiological diagnostic exams were invited to complete the tinnitus and hearing survey and were categorized into four groups: normal hearing without tinnitus, normal hearing with tinnitus, hearing loss without tinnitus, and hearing loss with tinnitus. Cultural adaptation of tinnitus and hearing survey followed the steps indicated by Guillemin et al. (1993), including assessment of inter-researchers’ reproducibility, internal consistency, and reliability of the instrument. Results: There were no substantial changes to the content of the tinnitus and hearing survey questions, although a few adaptations were made to two-item sound tolerance section to facilitate participants’ understanding. Internal consistency and reliability tested by Cronbach’s α was considered good for all domains. The reproducibility of the tinnitus and hearing survey was measured by the Kappa coefficient at two different moments and agreement between evaluators 1 and 2 was considered almost perfect, indicating good reproducibility. Conclusion: The tinnitus and hearing survey was culturally adapted to Brazilian Portuguese and analyzed for internal consistency, reliability, and reproducibility. Results support this questionnaire as a useful tool to help professionals differentiate the main complaint of the individual, allowing the choice of a more appropriate intervention.
