Improving olfactory assessment: an item response theory analysis of the American English version of the Sniffin’ sticks identification subtest
These findings support the use of IRT to identify poorly performing items, enabling the refinement of the SSET, to enhance its precision and reliability across populations. Future research should explore item revisions and extend psychometric evaluations to other subtests and samples.
