Abstract:This dataset accompanies the article "Sniffin' Sticks Smell Identification Test: Exploring Measurement Properties in an Adult Brazilian Healthcare Professionals Sample." The provided data encompass the responses from 144 highly educated Brazilian healthcare professionals who completed the 16-item Sniffin' Sticks identification test (SS-16). The dataset includes individual item responses in binary form. The primary goal of the associated research was to explore psychometric properties of the culturally adapted Brazilian Portuguese version of the SS-16. Specifically, it evaluated internal structure validity through Rasch analysis. Methodological Highlights: Rasch analysis confirmed the unidimensionality of the SS-16. Identification of item difficulty hierarchy: easiest odors included peppermint, cinnamon, and fish; most difficult were apple, turpentine, and liquorice. Intended Usage: The dataset is intended for researchers interested in olfactory psychophysics, item-response theory (IRT), cross-cultural adaptation of sensory tests, and demographic influences on sensory perception. The provided data support replication studies, secondary analyses, or comparative research in olfactory function assessments.
