VALDES P., Constanza et al. Validation of the SNOT-22 quality of life survey in Chilean population. Rev. Otorrinolaringol. Cir. Cabeza Cuello []. 2020, 80, 4, pp.425-433. ISSN 0718-4816.  http://dx.doi.org/10.4067/S0718-48162020000400425.

Introduction:

Chronic rhinosinusitis has a high impact on the patient's quality of life. The recommendation of the EPOS guidelines is to use the Sino-Nasal-Outcome-Test sur- vey of 22 indicators (SNOT-22), which is not validated in the Chilean population.

Objective:

translation and validation of SNOT-22 in Chilean population consulting for CRS in the ENT department of the Hospital del Salvador.

Material and Method:

translation of SNOT-22. Recruitment of patients with and without CRS. Application of translated version two times two weeks apart. Evaluation of discriminant validity and construct validity.

Results:

34 patients without CRS and 16 with CRS were evaluated. The average total SNOT-22 score was 19.62 and 43.1 points, respectively, with significant differences between both groups. Regarding validation analysis, Cronbach's alpha coefficient observed was > 0.95, intraclass correlation coefficient was 0.986, Pearson's correlation coefficient was 0.84 and the area under the ROC curve was 0.861.

Conclusion:

The translation and transcultural adaptation of this version of SNOT-22 is valid and reliable. This version of SNOT-22 is a good instrument to assess the impact of CSR, and its intervention, on the quality of life of Chilean adult patients.
