Adaptation and Validation of the Hebrew Version of the Nasal Obstruction Symptom Evaluation (NOSE) Scale

Background: Nasal obstruction is one of the most common complaints in the practice of rhinology.Objective: To adapt the Nasal Obstruction Scale Evaluation (NOSE) questionnaire to Hebrew (H-NOSE) and to assess its sensitivity and specificity.Methods: Candidates for surgical intervention due to isolated nasal obstruction and healthy volunteers (controls) were included in the validation. The English NOSE questionnaire was translated into Hebrew and re-translated for translation validity. Patients completed the H-NOSE questionnaire before and after surgery for nasal obstruction. The same questionnaire was completed by the controls. Test-retest reliability was performed within 2 weeks. Psychometric properties (reliability, reproducibility, validity, and responsiveness) were assessed by a test-retest procedure, internal consistency, correlation to the Hebrew Sino-Nasal Outcome Tool 22 (He-SNOT-22), and response sensitivity.Results: In total, 179 patients with nasal obstruction and 74 controls completed the questionnaire. Cronbach's alpha score was 0.93 for internal consistency. The receiver operating characteristic curve demonstrated high sensitivity and specificity (< 90%) and area under the curve was 0.97. We found no significant difference in test-retest reliability. The difference between the pre and postoperative questionnaire scores was highly significant (13.9 & PLUSMN; 4.0 vs. 3.2 & PLUSMN; 4.1, respectively, P < 0.001).Conclusions: The H-NOSE questionnaire demonstrated reliable internal consistency, sensitivity, specificity, and reliability. The Hebrew version differentiated between patients and heathy controls and was easy to administer. This instrument is useful for Hebrew speaking patients who undergo surgery for nasal obstruction.IMAJ 2023; 25: 564-567
