ABSTRACT
The aim of this study was to demonstrate the test-retest reliability of sentence recognition score (SRS) using Korean standard sentence lists for adults (KS-SL-A). Subjects consisted of 156 adults aged between 18 and 25 years with normal hearing sensitivity. Eight lists of KS-SL-A were presented to each subject using a compact disc. SRS was calculated by the percentage of correct responses of 40 target words within 10 sentences. After one or two weeks, retest was performed and correlation, paired t-test, 95% confidence interval (CI) and prediction interval (PI) were calculated for the test-retest reliability. Results showed that the correlation coefficient of SRS was 0.72 and the difference between test and retest SRSs was not statistically significant (paired t-test, p > .05). Results also demonstrated narrow 95% CI and relatively wide 95% PIs. These results indicate that SRS test using the recorded voice of KS-SL-A is fairly reliable. Therefore, 95% PIs for each SRS rather than the PI for the whole range of SRS are strongly recommended in clinical situations when evaluating each individual's retest SRS.
