The test-retest reliability of the Hearing Handicap Inventory for Adults (HHIA) was assessed on a sample of 28 hearing-impaired adults. Reliability estimates were obtained to set the stage for using the HHIA as an outcome measure in aural rehabilitation. The test-retest reliability was quite high (r = 0.97) and the standard error of measurement was low for the HHIA and its screening version (HHIA-S). In light of the psychometric adequacy, the HHIA and HHIA-S have potential as indices of hearing aid benefit in hearing-impaired adults.
