This study was performed to measure the reliability of the recomposed Korean Hearing Handicap Inventory for the Elderly (KHHIE). T he inventory comprised of two subscales : 12- item subscale explores social and situational hearing impairment ; 13- item subscale explores emotional effect of hearing impairment (see Appendix 1). The result s of the study can be summarized as follows : (1) Correlation relation between PTA and KHHIE was 0.67 which indicates that as the hearing impairment get s wor se the point s for hearing inventory increase. (2) The reliability of the KHHIE was evaluated by assessing it s internal con sistency through the computation of Chronbach s coefficient alpha. Alpha value ranged from 0.91 to 0.97 for the entire inventory which shows high internal consistency . (3) T he standard error (SE) of measurement and the standard error of the difference between two administrations of the KHHIE (2√2 SE) were calculated. T he SE associated with the FF and PP administration of the KHHIE were 5.35 and 5.07, respectively, suggesting that test - retest scores would have to differ by at least 15.13 and 14.34 point s (95 % confidence interval for a true charge) in order for rehabilitation effect s to be con sidered effective. (4) The test - retest reliability as sociated with the FF and PP administration s of the KHHIE was computed using Pear son correlation. The test - retest correlation was quite high, 0.94 to 0.96, for all scales suggesting that the score on two administration s of the KHHIE are related in the test - retest situation. (5) T he result s for analy sis of comparison between KHHIE and KHHIE- S was all above 0.90 showing that KHHIE- S can feasibly be used as screening tests.
