The Brazilian Portuguese version of THI is a valid and reproducible tool used to quantify how tinnitus impacts the life quality of those Brazilian patients who complain of this symptom.
Ti nnitus can greatly impact an individual's life qualityand it is very difficult quantify. Aim: To determine the reproducibility and validity of a Brazilian Portuguese version of the Tinnitus Handicap Inventory (THI), a self-applicable questionnaire which assesses tinnitus impact on patients' life quality. Materials and Methods: This was a prospective transversal study. The questionnaire was translated into Portuguese and cross-culturally adapted to the Brazilian environment according to internationally recommended methods. The Portuguese version of the THI was answered by 180 patients who complained of tinnitus. Reproducibility was assessed using the Cronbach's Alpha Calculation; and the validity was assessed by means of the Beck Depression Inventory (BDI), calculating the Pearson correlation coefficient. Results: The Portuguese version of the THI showed high internal validity, comparable to the original version. A high correlation was observed between the THI and the BDI. Conclusion: The Brazilian Portuguese version of THI is a valid and reproducible tool used to quantify how tinnitus impact the life quality of those Brazilian patients who complain of this symptom.
We did not see differences in the audiometry and in the incidence of complications when we compared the type of prosthesis used. We believe it is valid to continue teaching this procedure in medical residency training programs, regardless of the type of prosthesis.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
