Abstract
OBJECTIVE
In this study, the Tinnitus Primary Function Questionnaire was translated, culturally adapted and validated for Brazilian Portuguese.
METHODS
This study was carried out in two stages. First, a prospective study of translation and cultural adaptation was carried out with a group of 20 patients. The questionnaire was translated, revised and back-translated from Portuguese into English. Subsequently, a retrospective study was carried out with 1,095 patients, 18 months after the first stage. The validation and reliability of the Tinnitus Primary Function Questionnaire was verified by comparing its results with the results of the Tinnitus Handicap Inventory.
RESULTS
The interclass correlation coefficient of the behavioral aspects ranged from 0.82 to 0.90 and the total score was 0.93, while Cronbach's alpha was >0.94 for the total score during the test-retest application. To validate the questionnaire, a database was used, which consisted of 1,095 patients submitted to tinnitus assessment using the Tinnitus Primary Function Questionnaire and Tinnitus Handicap Inventory simultaneously. Patients were enrolled from 14 Brazilian states (46% female), with a mean age of 58 years. The reliability of the Tinnitus Primary Function Questionnaire was tested during validation for the four different evaluated behavioral aspects, and the results were significantly high for all aspects and the total score. To validate the Tinnitus Primary Function Questionnaire, the results of the total Tinnitus Primary Function Questionnaire and Tinnitus Handicap Inventory scores were compared using Pearson's product-moment correlation test. The results indicate a high correlation between the two questionnaires (r=0.84; p<0.001; 95% CI 0.82-0.85).
CONCLUSION
The data from the Tinnitus Primary Function Questionnaire showed a high correlation with those of the Tinnitus Handicap Inventory. This indicates that the Portuguese version of the Tinnitus Primary Function Questionnaire can be adopted as a valuable tool in the clinical evaluation of patients with tinnitus.
