Hearing specific and generic measures of the psychosocial impact of hearing aids.

Hearing-specific and generic measures of hearing aid outcome were examined in order (a) to determine their relative sensitivity to hearing aid use and (b) to examine the relationship between pre-hearing aid use expectations and post-use outcomes. Ninety-two hearing-impaired individuals completed some combination of the Abbreviated Profile of Hearing Aid Benefit, Expected Consequences of Hearing Aid Ownership (ECHO), Satisfaction with Amplification in Daily Life (SADL), and Psychosocial Impact of Assistive Devices Scale, and provided reports of their daily and lifetime hearing aid use. In general, (a) the longer individuals wear hearing aids, the more positive the reported outcome, and (b) ECHO scores of non-hearing aid users are higher than SADL scores of new hearing aid users (six weeks to one year of use) but are similar to those obtained from experienced users (greater than one year of use). Between-questionnaire comparisons showed the generic measure to be as sensitive as the hearing aid specific measures. We suggest that generic measures have some advantages over hearing specific measures but that each has a place in the clinic.
