Objective: To translate the Sino-Nasal Outcome Test (SNOT) 22 into Filipino, and establish the validity and reliability of the Filipino version of the Sino-Nasal Outcome Test (SNOT) 22.
Methods:
Design: Prospective Cohort
Setting: Tertiary Government Training Hospital
Participants: Twenty one (21) patients with rhinosinusitis with or without nasal polyposis were administered the Filipino SNOT 22 to determine reliability. Sixty three (63) patients with rhinosinusitis with or without nasal polyps and forty eight (48) controls were recruited for the validity study.
Results: The Filipino SNOT 22 had a Pearson correlation of 0.618 significant at the 0.01 level and a Cronbach’s alpha of 0.76. The calculated Z-Score was 7.21 with p-value < .00001 significant at p < .05. The value of U was 300 with a critical U value at 1512.
Conclusion: The self administered Filipino SNOT 22 is a reliable and valid tool for measuring QOL among Filipino patients with rhinosinusitis.
Keywords: sinusitis, reliability and validity, quality of life, sino-nasal outcome test 22
