Factor analysis of the questionnaire of olfactory disorders in patients with chronic rhinosinusitis.

ABSTRACT:

Background

Olfactory-specific quality of life (QOL) can be measured using the Questionnaire of Olfactory Disorders-Negative Statements (QOD-NS), which examines various aspects of olfactory dysfunction. It is unknown if certain factors of the QOD-NS differentially impact QOL.

Methods

Patients with chronic rhinosinusitis (CRS) completed the QOD-NS, 22-item Sino-Nasal Outcome Test (SNOT-22), Medical Outcomes Study Short Form 6-D (SF-6D) health utility measure, and Patient Health Questionnaire-2 (PHQ-2) depression screen. Exploratory factor analysis of the QOD-NS was performed. Associations between QOD-NS factors and other QOL metrics were analyzed before and after endoscopic sinus surgery (ESS).

Results

Outcomes were examined on 132 patients. The QOD-NS contains 4 distin
