Abstract :
Background: The quality of life (QOL) is an important indicator for disease-severity classification and outcome measurement in obtaining
treatment sinonasal diseases. The sinonasal outcome test 22 (SNOT 22) questionnaire has been introduced as the best specific sinonasal
instrument for QOL measurement. Objectives: To prepare a valid and reliable Persian language version of SNOT 22 questionnaire. Patients and Methods: After forward and backward translation of the original version of SNOT 22 questionnaire from English to Persian, a
group of patients with nasal septal deviation who need septal surgery and another group of healthy volunteers answered the Persian version
of the questionnaire. The responsiveness rate, validity (Pearson correlations and differential validity) and reliability (internal consistency and
test-retest reliability) of the 22 items of the questionnaire was calculated. P value < 0.05 was considered significant. Results: Thirty adults with nasal septal deviation need surgical correction and 30 healthy volunteers were included (mean age 30.4 ± 7.1 vs.
33 ± 6.7, P value = 0.148). The questionnaire was introduced to subjects two times with a two-week-period gap. Total responsiveness rate for 22
items was more than 97%. The total Cronbach's Alfa coefficient was 0.898 (ranging 0.890-0.903). The Pearson correlations were 0.85 and 0.96
for patients and healthy volunteers, respectively. The mean total score were 25.6 ± 13.3 (range 6-52) and 7.6 ± 9.1 (range 0-45) in patients and
healthy volunteers, respectively (P < 0.0001). The subscales scores were also significantly different between two groups. Conclusions: The Persian version of SNOT 22 questionnaire is a valid and reliable instrument for accessing sinonasal diseases in Persianspeaking
people.
