Evaluation of Clinical Validity of Cross-Cultural Smell Identification Test (CC-SIT) in Korean / 대한이비인후과학회지

ABSTRACT

BACKGROUND AND OBJECTIVES: The development of a l2-item Cross-Cultural Smell Identification Test (CC-SIT) was based upon items from the University of Pennsylvania Smell Identification Test (UPSIT), The selected CC-SIT items were familiar to most persons from American, European, and Asian cultures. Since there were no reports about its clinical validity for Koreans, we evaluated its identifiability in this study. MATERIALS AND METHODS: The CC-SIT were administered to 30 normal subjects and 32 patients with decreased sense of smell, and compared with those of the Korean K-SIT and buthanol threshold test (BTT), items of which many Koreans are familiar with. RESULTS: In the normal group, the mean percent-correct scores of CC- SIT and K-SIT were 87.5+/-7.8% and 90.5+/-9.7%, respectively. In the patient group, the scores were 48.2+/-14.1 and 49.6+/-10.2%, respectively. The results of CC-SIT showed a high correlation with the K-SIT (gamma=0.822, p < 0.001). CONCLUSION: The CC- SIT can be used as an olfactory identification test for Koreans.
