Abstract

Background and Objectives
The 10-item Standardized Cosmesis and Health Nasal Outcomes Survey (SCHNOS) is a recently developed questionnaire for assessing both nasal obstruction and nasal cosmetic satisfaction. It is widely used in rhinoplasty clinics based on its high level of reliability and efficacy in Western countries. In this study we evaluated the validity of the Korean version of the SCHNOS (K-SCHNOS).
Subjects and Method
The SCHNOS was translated into easily-understandable Korean following the guideline of the developers. Twenty-seven patients undergoing rhinoplasty and a control group of 29 non-rhinoplasty patients completed K-SCHNOS twice at intervals of 2 weeks regardless of pre- or postoperative state. The K-SCHNOS was evaluated for internal consistency, test-retest reliability, and validity.
Results
Of the 56 study participants, 39 (69.6%) were male and 17 (30.4%) were female, with the mean (standard deviation) age of 33.5 (12.9) years. Both obstructive domain and cosmetic domains showed high internal consistency with their respective Cronbach’α values being 0.92 and 0.91. The correlations in the test-retest analysis for each item were acceptable, ranging from 0.6-0.82. The association between the obstructive domain and cosmetic domain was 0.48 (95% confidence interval, 0.32-0.61), indicating a very weak correlation.
Conclusion
The K-SCHNOS has proven to be a reliable and valid questionnaire to be used by Korean-speaking patients undergoing functional or cosmetic rhinoplasty.
