We are looking to a good sniffin' test to evaluate smell discrimination and detection. It will be a sample of 40 participants.
There are several options on the market, but a few things to consider before making the choice.
If you are conducting a single measurement, I would suggest using a test with published normative values from the same target population (Italian). This is not as important if you are conducting repeated measures on the same participants.
Just to clarify - by detection, do you mean detection threshold?
Possible tests:
- SMT
(Reden, J., Draf, C., Frank, R. A. & Hummel, T. Comparison of clinical tests of olfactory function. Eur Arch Otorhinolaryngoy 273, 927–931 (2015).)
- Sniffin' Sticks
(Hummel, T., Kobal, G., Gudziol, H. & Mackay-Sim, A. Normative data for the ‘Sniffin’ Sticks’ including tests of odor identification, odor discrimination, and olfactory thresholds: an upgrade based on a group of more than 3,000 subjects. Eur Arch Otorhinolaryngol 264, 237–243 (2006).)
- SMELL-S / SMELL-R
(Hsieh, J. W., Keller, A., Wong, M., Jiang, R.-S. & Vosshall, L. B. SMELL-S and SMELL-R: Olfactory tests not influenced by odor-specific insensitivity or prior olfactory experience. Proceedings of the National Academy of Sciences 114, 11275–11284 (2017).)
Thank you so much for your answer. Yes, I meant "detection threshold".
Finally, we will use Sniffin' Sticks, it seems very complete (with the 3 different measures), and because we are in a really exploratory stage I think is best option.
But I really found interesting the SMT, so thank you again to let me know about it.
