ABSTRACT

Dichotic digit test is a high validity clinical test for providing information on the hemispheric and interhemispheric lesions and is widely used for screening and diagnosing central auditory processing disorders (CAPD). The purpose of this study was to develop Korean dichotic digit test and provide normative values for children and adults. Prior to the development of the test, errors were analyzed in 90 pairs of 1-digit and 180 pairs of 2-digit to rule out phonemic similarities of Korean numbers 1 through 10 in the manner of dichotic listening by testing 20 young adults with normal hearing. The final test developed in this study was composed of 1-3 digit lists with 20 items for each list, excluding the number 2 in which showed the most number of errors. To prepare for the age norms, the developed dichotic digit test was performed on 272 subjects from the age of 7-12 years old and 95 college students in 20s. 1 and 2 digit tests were applied to all age groups while 3 digit test examined only for the adult group. The results for 7 to 20 years showed that the performance significantly increased as age increased, and decreased as the number of digits increased. The response showed as 95.3-99.5% in right ear, 89.2-98.7% in left ear for 1 digit test and 66.9-92.3% in right ear, and 59.8-89.9% in left ear for 2 digit test. There were significant REAs for the age of 8-9 years in the 2 digit pair conditions and performance approached the adult level for the age of 12 years. The dichotic digit test showed significantly high test-retest reliability and validity, which in validity showed significant correlation with speech recognition test. The normative values of Korean dichotic digit test with 1-3 digits were presented and the results indicate that 2 digit test is the most appropriate for CAPD diagnosis.
