NOSE-Perf scale quantifies symptoms resulting from nasal septal perforation.
•The Portuguese version of the NOSE-perf scale showed internal consistency.
•The NOSE-Perf scale translation showed good reliability parameters.
•The proposed instrument is valid for measuring nasal septal perforation symptoms.
AbstractObjectiveTo perform the translation, cultural adaptation, and validation of the NOSE-Perf Scale to Brazilian Portuguese.
MethodsThis 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.
ResultsThe 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.
ConclusionThe Brazilian Portuguese version of the NOSE-Perf scale is a reliable and valid instrument for measuring symptoms in patients with nasal septum perforations.
