Abstract

OBJECTIVES
Odors used in an odor identification test should be familiar to the subject, but there are some unfamiliar distracters in Korean version of Sniffin' stick (KVSS) II identification test. In this study, we used the results of the original version of KVSS II identification to modify the KVSS II identification test.
METHODS
Eighty-three participants took an original version of KVSS II identification test and a visual analogue scale of subjective odor function. KVSS II identification which has 16 items was performed to choose one out of four odors items. And visual analogue scale was checked from 0 to 10 points of their subjective olfactory function. Two weeks later they took the modified version of KVSS II identification test. Hyposmic or anosmic patients were excluded.
RESULTS
The mean score of the original version of KVSS II identification and modified version of KVSS II identification were 11.3 and 12.5, respectively (P<0.05). The KVSS II identification test and subjective olfactory function were positively correlated (r=0.247, P<0.05), as were the modified KVSS II identification test and subjective olfactory function (r=0.329, P<0.05).
CONCLUSION
After modification of distracters, KVSS II identification test appears to be suited for assessment of olfactory function.
