Our aim was to determine whether distinct smell and taste items in the SNOT\u201022 would improve psychometric performance.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>One hundred and eighty\u2010one CRS patients were recruited and completed the SNOT\u201022. Additional items querying problems with the senses of \u201csmell\u201d and \u201ctaste,\u201d using the same response scale and recall period were given to study participants. Item response theory (IRT) was used to determine IRT parameters, including item discrimination, difficulty, and information provided by each SNOT\u201022 item.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Confirming previous studies, the chemosensory item of the SNOT\u201022 (reflecting \u201ctaste\/smell\u201d) had poor psychometric performance. Use of a distinct smell or taste item instead of the combined \u201ctaste\/smell\u201d item did not improve psychometric performance. However, a dedicated smell question resulted in a left shift of threshold parameters, showing that the dedicated smell item better captures moderate CRS disease burden than the original taste\/smell item of the SNOT\u201022, which by virtue of near\u2010identical IRT parameters appears to more greatly reflect problems with taste.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>A dedicated smell\u2010 or taste\u2010specific item, rather than the combined \u201ctaste\/smell\u201d item currently in the SNOT\u201022 does not provide significantly greater psychometric performance. However, a dedicated smell item may better capture moderate CRS disease burden compared with the current chemosensory item on the SNOT\u201022. <jats:italic>Laryngoscope<\/jats:italic>,
