THE USE OF THE TRADITIONAL CHINESE VERSION OF THE UNIVERSITY OF PENNSYLVANIA SMELL IDENTIFICATION TEST AND THE SMELL THRESHOLD TEST FOR HEALTHY YOUNG AND OLD ADULTS IN TAIWAN.

This study investigated the use of the traditional Chinese version of the University of Pennsylvania Smell Identification Test and the Smell Threshold Test to assess olfactory function for healthy young and old adults in Taiwan. One hundred young adults (50 men; M = 24.34 yr., SD = 2.63; 50 women; M = 24.50 yr., SD = 2.96) and 49 old adults (20 men; M = 60.85 yr., SD = 4.21; 29 women; M = 59.93 yr., SD = 3.97) with normal olfaction completed the traditional Chinese versions of the University of Pennsylvania Smell Identification Test. Of these individuals, 40 young adults and 40 old adults also completed the Smell Threshold Test. The mean of the traditional Chinese versions of the University of Pennsylvania Smell Identification Test scores and Smell Threshold Test thresholds were significantly different between young and old adults. The threshold value for the Smell Threshold Test was lower in both young and old adults as compared to previously established American norms. Both tests require further modifications for clinical use in Taiwan.
