Adaptación y validación de la versión española del cuestionario NOSE-Perf para perforaciones septales

Abstract

Background and objective

Septal perforation (SP) cause heterogeneous symptoms depending on the anatomical location, highlighting scabs, nasal obstruction and/or epistaxis. The use of questionnaires to determine the quality of life in different pathologies is increasing in sinonasal pathologies and in patients with SP the NOSE-Perf questionnaire was constructed, currently validated in English. The aim of this study is the translation, cross-cultural adaptation, and validation of the NOSE-Perf questionnaire into Spanish.

Material and methods

Prospective single-center study of 81 patients (38 with SP and 43 controls), visited in the Rhinology section of a tertiary hospital. Adaptation and translation NOSE-Perf into Spanish and validation using the NOSE and NOSE-Perf questionnaire in Spanish.

Results

Significant differences were found in the mean NOSE-Perf score and in the mean NOSE score (95%CI: 21.2-26.9; P<.001 and 95%CI: 53.8-70.5; P<.001) between PS group and control group. Pearson's correlation between the two questionnaires NOSE-Perf and NOSE in the SP group was 0.74 (95%CI: 0.56-0.86; P<.001). In the control group it was r = 0.85 (95%CI: 0.73-0.91; P<.001). Cronbach's alpha coefficient of the NOSE-Perf was 0,95 (95%CI: 0,93-0.96) for internal consistency. The reliability evaluation was carried out by test-retest, and a strong Pearson correlation was obtained between the questionnaires r = 0.94 (95%CI: 0.85-0.97; P<.001) and r = 0.89 (95%CI: 0.77-0.95; P<.001).

Conclusions

The Spanish version of the NOSE-Perf is as reliable and valid as the English version, which makes it possible to assess the impact on quality of life that it causes in patients with perforations in the Spanish-speaking population.
