Objectives/Hypothesis Validation and cross‐cultural adaptation of the Nasal Obstruction Symptom Evaluation (NOSE) scale into the Arabic language with studying of its psychometric properties. Study Design Prospective instrument‐validation study. Methods Guidelines for the cross‐cultural adaptation process from the original English language scale into the Arabic language version were followed. We assessed the psychometric properties of the Arabic version of the NOSE scale (A‐NOSE) (feasibility, reproducibility, internal consistency, reliability, discriminatory validity, responsiveness to change) in 101 consecutive patients who underwent septal surgery (preoperatively and 3 months postoperatively) and 102 asymptomatic controls. Results The Mann‐Whitney test showed a statistically significant difference for the mean score between the patients and the control group denoting good clinical validity. The Cronbach's α coefficient value for the A‐NOSE scale for 101 cases was 0.995, demonstrating good internal consistency. The Wilcoxon signed rank test showed a marked improvement in the patients score 3 months postoperatively. Correlation and level of agreement of the mean score of the A‐NOSE scale for each question were studied using Spearman's rank correlation for each question, and Pearson's correlation for the total score showed statistically significant results. Conclusions The A‐NOSE scale is a valid instrument for evaluating the subjective severity of nasal obstruction and is recommended to be used in rhinology research and daily practice.
