Clinical Evaluation of a Polish Translation and Cross-Cultural Adaptation of the Nasal Obstruction Symptom Evaluation (NOSE) Scale

Translation and Validation of the Thai Version of the Nasal Obstruction Symptom Evaluation (NOSE) Scale

Objective

The Nasal Obstruction Symptom Evaluation (NOSE) was developed to evaluate subjective outcomes of patients with deviated nasal septum and symptomatic nasal obstruction. Considering the differences in individuals' cultural, cross-cultural translation, adaptation, and validation of the instrument are necessary. The current study aimed to translate and validate the Thai version of the NOSE Questionnaire for patients with nasal septum deviation.

Study Design

A single-center prospective instrument validation study.

Setting

Thai tertiary referral center.

Methods

The study was conducted to translate and adapt the original English version of the NOSE to Thai. After translating, psychometric testing was conducted. The primary outcomes were validity (content, construct, and discriminant), reproducibility (test-retest procedure), and internal consistency (reliability). A total of 105 participants, of which 46 were patients with nasal airway obstruction and 59 were healthy asymptomatic volunteers, were enrolled in this study.

Results

The Thai-NOSE was found to be adequate for all tested psychometric properties with high internal consistency (Cronbach's α = .942), and to discriminate accurately between patients and healthy controls. The interitem and item-total correlations indicated a related construct among all items. A high level of reproducibility of the questionnaire was obtained in the test-retest procedure for each item (γ = 0.898). The initial test and retest scores indicated adequate reproducibility.

Conclusion

The Thai-NOSE questionnaire is a reliable instrument with appropriate psychometric properties for assessing the severity and impact of nasal airway obstruction in patients with nasal septum deviation.

Cross-cultural adaptation of the Hebrew Nasal Obstruction Symptom Evaluation (NOSE) scale

Objective

Nasal obstruction is a common complaint. The Nasal Obstruction Symptom Evaluation scale (NOSE) is a reliable validated tool used to assess the quality of life of patients with nasal obstruction. The purpose of this study is to validate the Hebrew version of the NOSE scale (He-NOSE).

Methods

A prospective instrument validation was conducted. The NOSE scale was translated primarily from English to Hebrew and then back from Hebrew to English according to the accepted guidelines of the cross-cultural adaptation process. The study group included surgery candidates suffering from nasal obstruction due to a deviated nasal septum and/or inferior turbinate hypertrophy. The study group completed the validated He-NOSE questionnaire twice prior to the surgery and once again, a month post-surgery. A control group of individuals with no history of nasal complaints or surgeries was asked to complete the questionnaire once. Reliability, internal consistency, validity, and responsiveness to change of the He-NOSE were evaluated.

Results

Fifty-three patients and 100 controls were included in this study. The scale showed excellent ability to discriminate between the study and the control group, exhibiting significantly lower scores in the control group (73.8 and 7 average scores respectively, p < .001). Good internal consistency (Cronbach's alpha .71 and .76) and test-retest reliability (Spearman rank correlation r = .752, p < .0001) were measured. Moreover, the scale revealed remarkable responsiveness to change (p < .00001).

Conclusion

The translated and adapted He-NOSE scale can be a useful tool to be applied in both clinical and research fields when assessing nasal obstruction.

Validation of the Nasal Obstruction Symptom Evaluation Scale in Mexican Adults

BACKGROUND

Nasal obstruction is a feeling of impaired airflow through the nose, caused by diverse factors with high prevalence. There are numerous methods to study it, being the most important subjective instrument the Nasal Obstruction Symptom Evaluation score, NOSE, with good structural validity and internal consistency. It has been translated and validated in several languages, including European Spanish, but hasn't been validated in Mexico.

AIM

Adapt and validate the NOSE scale to the Spanish language for a Mexican adult population.

METHODS

This study was conducted from May-August 2015. The scale was translated from English to Spanish and assessed by two experts to confirm its acceptability, being retranslated later. Adult subjects with native Mexican Spanish were recruited from the outpatient clinic, with chronic rhinopathy and without evidence of respiratory pathology. Both groups filled the scale, and anthropometric data were collected. A subgroup completed the instrument again after one month. STATA 15.1 was used for analysis.

RESULTS

The sample were 261 subjects. Cronbach alpha was 0.89, intraclass correlation coefficient 0.84, agreement limits -9.62 to 16.29. There was a statistically significant difference in score between groups. The area under the ROC curve was 0.855, with 83% sensibility and 76% specificity for a 20 total score. Moderate to strong item-total association was found with Spearman. The response model showed moderate item discrimination. In the factorial analysis, one factor was found, with an Eigenvalue of 3.21.

CONCLUSION

The adaptation of the NOSE scale is reliable and valid for its application in Mexican adult population.

Quality of Life in Patients with Nasal Obstruction after Septoplasty: A Single Institution Prospective Observational Study

Introduction  Nasal obstruction is a common symptom in otorhinolaryngological practice. It can impact significantly on the quality of life of the individual. Objective  The primary goal of the present study was to evaluate quality of life after septoplasty in adults with nasal obstruction. A secondary goal was to assess the effectiveness of septoplasty. Methods  This was a single institution prospective observational study. Patients had experienced septal deviation and symptomatic nasal obstruction with no benefit from medical treatment. There were 51 patients who completed the Nasal Obstruction Symptom Evaluation (NOSE-POL) scale as well as theVisual Analogue Scale (VAS) before undergoing septoplasty, 3 months later, and finally 7 months after surgery. Patients evaluated changes in their nasal obstruction and changes in their quality of life using the Clinical Global Impression Scale (CGI-S). Results  There was a significant improvement in nasal obstruction after septoplasty. Before septoplasty, the mean score on NOSE was 60.3 ± 20.4; 3 months after surgery, it was 32.9 ± 16.8; and 7 months after surgery it was 39.6 ± 33.2. The VAS results also proved a significant enhancement in nasal obstruction after septoplasty. Patients reported an improvement in nasal obstruction as well as a positive change in quality of life, confirming the effectiveness of septoplasty. Conclusions  In patients with deformed septum, septoplasty contributes to high satisfaction of the patient and a compelling improvement in disease-specific quality of life. The NOSE-POL questionnaire is a useful tool for measuring the outcomes of this procedure.

Predictors of Long-Term Nasal Obstruction Symptom Evaluation Score Stability Following Septoplasty With Inferior Turbinate Reduction

OBJECTIVES/HYPOTHESIS

Determine the postoperative Nasal Obstruction Symptom Evaluation (NOSE) score stability between 1 and ≥6 months after septoplasty with inferior turbinate reduction (ITR). Education level and occupation were evaluated to determine their effects on NOSE score stability during the postoperative period.

STUDY DESIGN

Retrospective case series.

METHODS

This was a retrospective case series. Patients were included if they underwent septoplasty with ITR for nasal obstruction due to septal deviation and inferior turbinate hypertrophy. NOSE scores were collected preoperatively, and at 1 and ≥6 months postoperatively. Education level and occupation were collected postoperatively via telephone survey. Changes in NOSE scores were compared between the different time points. Education level and occupation were analyzed to determine if they affected NOSE scores.

RESULTS

There were 98 patients included, and 56 were male (57.1%). Mean NOSE scores preoperatively and at 1 and ≥6 months postoperatively were 72.1, 17.1, and 12.0, respectively. Patients demonstrated a statistically and clinically significant reduction in NOSE score at 1 month (-54.9, P < .001) and at ≥6 months postoperatively (-60.0, P < .001). The mean 6.2-point decrease in NOSE score from 1 to ≥6 months was statistically, but not clinically significant. There were no significant differences in NOSE score changes based on educational level and occupation.

CONCLUSIONS

Patients achieved statistically and clinically significant reductions in NOSE scores at 1 months, with no clinically significant differences in NOSE scores at ≥6 months, suggesting NOSE score stability between these postoperative time points. Neither education level nor occupation influenced NOSE scores.

Cross-cultural adaptation and validation of Lithuanian-NOSE scale

PURPOSE

To evaluate validity and reliability of Lithuanian version of Nasal Obstruction Symptom Evaluation Scale (L-NOSE), designed for the assessment of nasal obstruction.

METHODS

Cross-cultural adaptation of L-NOSE was accomplished according to generally accepted methodology. L- NOSE was tested for its reliability, validity, and responsiveness in the group of 50 septoplasty patients and 100 healthy volunteers' controls.

RESULTS

L- NOSE showed good internal consistency (Cronbach's alpha coefficient 0.796 for test, 0.791 for retest, 0.792 for post-operative group, and 0.817 for control group) scores and high test-retest reliability (r = 0.94, p < 0.01) scores. In patients' group, positive moderate correlations between L-NOSE scores and Sino-nasal Outcome Test-22 logically similar domain scores were found, thus indicating good convergent construct validity. L-NOSE scores for control subjects were generally lower than for patients with nasal obstruction (p < 0.001), thereby indicating good discriminant validity of questionnaire. The exploratory factor analysis confirmed one-factor structure of questionnaire. The component matrix of L-NOSE ranged from 0.667 to 0.781 (KMO = 0.754, p < 0.0001). The mean L-NOSE score improved from 58.4 ± 18.2 points to 11.1 ± 9.5 points after septoplasty (p < 0.0001), indicating good responsiveness of questionnaire.

CONCLUSION

The L-NOSE questionnaire is a valid instrument with satisfactory reliability, validity, and responsiveness.
