INTRODUCTION: Chronic rhinosinusitis (CRS) is a significant health problem whose incidence and prevalence is rising. It calls into attention consensus about diagnosing, assessing symptoms and treatment of patients with CRS. Therefore, a validated Danish measure of health-related quality of life in sinonasal disease is needed. MATERIAL AND METHODS: The Sino-Nasal Outcome Test 22 (SNOT-22) was translated into Danish and its reproducibility was evaluated by test-retesting 40 patients with CRS. The statistical analyses used were Pearson's correlation coefficient, Cronbach's alpha, kappa and Bland-Altman's plot. Reproducibility was also tested for SNOT-22 subscales. RESULTS: The results show good internal correlation with a Cronbach's alpha of 0.83 in the initial test and one of 0.92 in the retest. Pearson's correlation coefficient was 0.70 (p < 0.001), revealing good correlation between the initial scores and the retests scores. Kappa was calculated for each item with a mean value of 0.61 showing substantial agreement. The paired t-test revealed no significant difference between the subscales. CONCLUSION: The Danish version of SNOT-22 is recommended for Danish clinicians and researchers as a patient-reported measure of outcome in sinonasal disorders such as rhinosinusitis and nasal polyposis.
