Abstract
Chronic rhinosinusitis (CRS) affects quality-of-life (QoL) in people with cystic fibrosis (PwCF), despite the reduction in symptoms and symptom severity associated with cystic fibrosis transmembrane conductance regulator (CFTR) modulators [1]. To precisely assess sinus symptoms and treatment needs in the post-modulator period, patient-related QOL instruments should be revisited. The 22-item SinoNasal Outcome Test (SNOT-22) measures CRS burden and QoL. Abbreviated surveys can lessen respondent fatigue. Item response theory (IRT) can help refine surveys by identifying the most informative survey items while maintaining reliability [2–4]. IRT assesses item discrimination (ɑ), the ability to differentiate trait levels, and difficulty (β), which defines thresholds for response categories [2–4].
