Data assessing the reliability and validity of the Sino-Nasal Outcome Test (SNOT-22) Questionnaire

This dataset contains a single excel file presenting results of the SNOT-22 questionnaire from 50 Chronic rhinosinusitis (CRS) patients and 30 healthy volunteers.<br>CT scan, Visual Analog Scale (VAS) and SF-36 questionnaire results are also recorded as the basis of validity and reliability tests of the SNOT-22 method in the associated publication.<br>Background:Chronic rhinosinusitis (CRS) is a common health condition that affects the patient's health-related quality of life. This dataset contains results of a Thai-version of Sino-Nasal Outcome Test 22 in chronic rhinosinusitis, translated into English.<br>A total of 80 subjects were recruited into the study and divided into two groups comprising of 50 patients with chronic rhinosinusitis and 30 healthy volunteers. Cronbach's α and Intraclass correlation coefficient were evaluated for its reliability. Validity test was evaluated against VAS score, SF-36 (Thai version) questionnaire and CT scan (based on Lund-Mackay score). Responsiveness was assessed between pre-operative and postoperative scores in 34 patients.<br>All subjects were over 18 year-old and could read and write Thai. Diagnosis of CRS was based on diagnostic criteria of European Position Paper on Rhinosinusitis and Nasal Polyps 2012. The Questionnaire was completed in 3 visits: The first both in CRS and normal group at the first day of enrolment. The second and third visit questionnaire were completed only in the CRS group. The second visit was completed at 2 weeks after first visit. The third vist, which completed only in CRS patients who underwent sinus surgery, 12 weeks after the operation. <br>Pre-operative CT scan of paranasal sinuses and Lund-Mackay scores were recorded in every operated case. Visual analog scale (VAS) of sinonasal symptoms and SF-36 score (Thai version) were recorded in all subjects.
