SNOT-22 validation in greek patients

Area of Science:

• Otolaryngology
• Health Outcomes Research

Background:

• Chronic rhinosinusitis (CRS) is a prevalent condition impacting patient health.
• The Sinonasal Outcome Test (SNOT-22) is a key health status instrument for CRS.
• A Greek translation of SNOT-22 is crucial for local patient assessment and quality of life evaluation.

Purpose of the Study:

• To validate the Greek translation of the SNOT-22 questionnaire.
• To assess the reliability and validity of the Greek SNOT-22 in patients with CRS.

Main Methods:

• A study involving 40 patients with CRS without nasal polyps and 40 healthy controls.
• Comprehensive ENT examinations and nasal endoscopy were performed.
• Test-retest reliability, internal consistency (Cronbach's alpha), and validity were evaluated by comparing patient and control group results.

Main Results:

• The Greek SNOT-22 demonstrated high internal consistency (Cronbach's alpha: 0.934 test, 0.856 retest).
• Excellent test-retest reliability was observed (average kappa value: 0.94).
• Statistically significant differences (p < 0.05) were found between patient and control groups.

Conclusions:

• The study confirms a valid and reproducible Greek version of the SNOT-22.
• This Greek SNOT-22 facilitates symptom assessment and quality of life evaluation for Greek-speaking patients.
• The questionnaire is highly recommended for Greek clinicians managing CRS.
