The SNOT-22 factorial structure in European patients with chronic rhinosinusitis: new clinical insights

ConclusionsPrincipal component analysis performed for SNOT-22 questionnaires completed by European CRS patients indicated a different item-domain-assignment than previously reported. Confirmatory factor analysis suggested acceptable and clinically plausible psychometric properties for the resulting factorial structure. Significant correlations between the “nasal symptoms” and the “emotional symptoms” domains were observed with objective CRS parameters. The resulting factorial structure with different item-domain assignments may thus be more suitable for European CRS patients.
