Cross-cultural adaptation and validation of a quality of life questionnaire: the Nasal Obstruction Symptom Evaluation questionnaire

Abstract

BACKGROUND: The Nasal Obstruction Symptom Evaluation (NOSE) instrument is a disease-specific questionnaire for assessing the outcome of an intervention in nasal obstruction in trials. This instrument is only available in the English language and cross-culturally valid questionnaires are very important for all research, including nasal obstruction. The aim of the current study was to reproduce the cross-cultural adaptation process for the NOSE questionnaire in the Portuguese language (NOSE-p). METHODOLOGY/PRINCIPAL: Cross-cultural adaptation and validation of the instrument were divided into two stages. Stage 1 involved four bilingual professionals, an expert committee and the author of the original instrument. In Stage 2, the NOSE-p was tested on 33 patients undergoing septoplasty for internal consistency, test-retest reliability, construct validity, discriminant validity, criterion validity, and response sensitivity. RESULTS: The cross-cultural adaptation process was completed and the NOSE-p was demonstrated to be a valid instrument with satisfactory construct validity. It showed an adequate internal consistency reliability and adequate test-retest reliability. It could discriminate between patients with and without nasal obstruction and it has a high response sensitivity to change. CONCLUSIONS: The cross-cultural adaptation and validation process demonstrated to be valid and the NOSE-p proved to be applicable in Brazil.

Application of FACE-Q and NOSE in Nasal Reconstruction with Paramedian Frontal Flap after Skin Cancer Resection

“…Thus, the NOSE questionnaire was adopted to assess respiratory obstruction. 12,13 The 44% proportion of responses to the questionnaires was considered high. Compared to a similar study, in which FACE-Q assessed patients' psychological stress undergoing surgical treatment for facial skin cancer, the percentage of response in this present study was higher (44.0% versus 34.2 %).…”

“…PRS Global Open • 2021 also adapted and validated for application in other languages. 12,13 Because of the relevance of NMSC in the nose and the complexity of reconstruction with a PFF, the evaluation of objective factors that affect the reconstruction outcome is essential to allow the treatment improvement. Thus, this study evaluates the result of nasal reconstruction with PFF for NMSC treatment using the FACE-Q and NOSE questionnaires in a cancer center.…”

Assessing Demographic Factors and Respiratory Disorders Related to Rhinoplasty among Syrian Private University Students

“…[27] In our study, nasal obstruction symptoms were assessed using the NOSE scale, which is a brief, reliable and rapid qualitative tool used to assess the outcome of postoperative nasal obstruction. [28,29] Where the average NOSE score for students who have had rhinoplasty before was 32.8. This is similar to the results of assessing nasal obstruction after rhinoplasty in a study conducted in Turkey where the average NOSE score was 32.5.…”

Arabic translation and validation of the Nasal Obstruction Symptom Evaluation (NOSE) scale

“…The NOSE scale was translated into several languages [3][4][5][6]. In this work, we translated the NOSE questionnaire into the Arabic language to make it available for the Arabic-speaking patients and then tested its validity, reliability, and responsiveness using standard statistical procedures [13].…”
