Abstract

INTRODUCTION: The Standardized Cosmesis and Health Nasal Outcomes Survey (SCHNOS) questionnaire is a tool developed to evaluate functional and aesthetic components of rhinoplasty. It is a reliable patient-reported outcome measure, not available in the European Portuguese language.OBJECTIVE: our goal was to translate and culturally adapt the SCHNOS questionnaire to the European Portuguese language.METHODS: The questionnaire was forward and backward translated and culturally adapted to the European Portuguese language following international guidelines. The authors evaluated internal consistency, correlation, and reproducibility to determine the validity of the questionnaire.RESULTS: The final European Portuguese version of the SCHNOS was administered to 58 native European Portuguese speakers. Both the SCHNOS-O (obstructive) and SCHNOS-C (cosmetic) showed high internal consistency with Cronbach's alpha of 0.93 and 0.95, respectively. Also, for the entire SCHNOS, Cronbach's alpha was 0.96. All the items demonstrated good item-test and item-rest correlations with the differences between pre-and post-estimates being non-significant.CONCLUSIONS: The translation, adaption, and validation of the SCHNOS into European Portuguese were successfully performed. This provides another tool to help evaluate the functional and aesthetic outcomes of rhinoplasty patients.
