[Development of the Sino-Nasal Outcome Test-20 Chinese version (SNOT-20 CV)]

Area of Science:

• Otolaryngology
• Health Outcomes Research
• Psychometrics

Background:

• Chronic rhinosinusitis significantly impacts patient quality of life.
• Validated instruments are crucial for assessing treatment outcomes in rhinosinusitis.
• The Sino-Nasal Outcome Test-20 (SNOT-20) is a widely used measure, but a validated Chinese version was needed.

Purpose of the Study:

• To develop and validate the Sino-Nasal Outcome Test-20 Chinese Version (SNOT-20 CV).
• To assess the psychometric properties of the SNOT-20 CV for use in a Chinese population.

Main Methods:

• Translation, adaptation, and pretesting of the original SNOT-20.
• Clinical testing in 60 chronic rhinosinusitis patients and comparison with the original edition.
• Evaluation of feasibility, reliability (split-half, Cronbach's alpha, ICC), content and construct validity, and sensitivity.

Main Results:

• The SNOT-20 CV demonstrated satisfactory feasibility and acceptance.
• High reliability was confirmed (split-half=0.95, Cronbach's alpha=0.88, ICC=0.98).
• The scale showed good validity, sensitivity to change, and comparable properties to the original SNOT-20.

Conclusions:

• The SNOT-20 CV successfully passed psychometric and clinimetric evaluations.
• The SNOT-20 CV is a reliable and valid tool for measuring rhinosinusitis-specific quality of life in China.
• This validated instrument will aid in clinical practice and research for Chinese rhinosinusitis patients.
