Background
Chronic rhinosinusitis (CRS) is a relatively common disease, which significantly affects the patient's quality of life (QoL). Sino‐Nasal Outcome Test–22 (SNOT‐22) is a QoL questionnaire, which allows quantifying patients' complaints. Our aim was to translate and validated the SNOT‐22 into the Russian language.
Methods
Translation and validation of SNOT‐22 questionnaire was performed through forward‐backward translation technique. After proper translation, the translated questionnaire was completed by CRS patients before and after endoscopic sinus surgery (ESS) and by healthy individuals as controls.
Results
Thirty‐four native Russian‐speaking CRS patients completed the Russian version of the SNOT‐22 questionnaire before and after ESS. The internal consistency for reliability assessment was very good (mean Cronbach's alpha = 0.816 for CRS patients). Mean scores for the preoperative, postoperative and control groups were 67.6, 18.1 and 9.2, respectively (P < .001), showing validity and responsiveness of the questionnaire.
Conclusion
The Russian version of the SNOT‐22 questionnaire is a valid outcome measure for patients with CRS.
