Translation, cultural adaptation, and validation of the NOSE-Perf scale to Brazilian Portuguese
Objective
To perform the translation, cultural adaptation, and validation of the NOSE-Perf Scale to Brazilian Portuguese.
Methods
This study was divided into two stages. In the first stage, the questionnaire was submitted for translation and cultural adaptation, following the guidelines recommended by the ISPOR Task Force (International Society for Pharmacoeconomics and Outcomes Research). Then, the Brazilian Portuguese version of the NOSE-Perf scale was applied to a group with septal perforation and a control group. The group with perforation answered the questionnaire again after one month. Internal consistency, test-retest reliability, and discriminant validity were assessed.
Results
The Brazilian Portuguese version of the NOSE-Perf scale was applied to 32 participants, 16 from the group with septal perforations and 16 controls. The instrument obtained high internal consistency, with Cronbach's alpha scores of 0.986. High reliability was also obtained, with Spearman's correlation coefficient of 0.996 (p < 0.001) and the intraclass correlation coefficient of 0.965 with a 95% Confidence Interval (95% CI) of 0.886‒0.988. The NSP group obtained a mean total score of 13.8 ± 12.6 and the control group a score of 2.3 ± 1.8, with a statistical difference between the groups (p < 0.001), demonstrating good discriminant validity.
Conclusion
The Brazilian Portuguese version of the NOSE-Perf scale is a reliable and valid instrument for measuring symptoms in patients with nasal septum perforations.

期刊介绍：
Brazilian Journal of Otorhinolaryngology publishes original contributions in otolaryngology and the associated areas (cranio-maxillo-facial surgery and phoniatrics). The aim of this journal is the national and international divulgation of the scientific production interesting to the otolaryngology, as well as the discussion, in editorials, of subjects of scientific, academic and professional relevance.
The Brazilian Journal of Otorhinolaryngology is born from the Revista Brasileira de Otorrinolaringologia, of which it is the English version, created and indexed by MEDLINE in 2005. It is the official scientific publication of the Brazilian Association of Otolaryngology and Cervicofacial Surgery. Its abbreviated title is Braz J Otorhinolaryngol., which should be used in bibliographies, footnotes and bibliographical references and strips.
