Summary:According to the European Position Paper on Rhinosinusitis and Nasal Polyps (EPOS) 2020, the clinical definition of adult rhinosinusitis and paediatric rhinosinusitis are the same except for smell disturbances, i.e. loss or reduction of smell, which can be present or absent in an adult but not as a criterion in children. P; 3:1, meaning that three subjects per item. Since the SNOT-22 study has 22 items, thus the sample size required is 66 subjects (22 x 3 subjects per item). The sample size of test-retest reliability was also calculated using STATA 11.0 software using alpha at 0.05 and the power of the study at 0.80, the estimated intraclass correlation coefficient (ICC) was at 0.80. [...]the calculated sample size for test-retest reliability is 46 subjects. In this study, floor effects or ceiling effects are considered to be present when it is 30% or more. [...]when bmSNOT-22 is evaluated as a single construct, floor effects are observed in the Bahasa Malaysia translated items of 'sad' (Q19) and 'embarrassed' (Q20), but there were no ceiling effects seen.
