Expected Consequences of Hearing Aid Ownership (ECHO)
Description:The ECHO survey has been designed to measure prefit expectations of hearing aid use. It was developed as a companion instrument to the SADL questionnaire. As with the SADL, it produces a global score and four subscales: Positive Effect, Service & Cost, Negative Features, and Personal Image. These scale scores can then be compared with the range of scores representing realistic expectations for hearing aid use.
The ECHO could be used to examine unrealistic expectations a potential hearing aid user may have, in order to direct counseling to address these areas before the hearing aid is issued. This may prevent unnecessary disappointment with the experience of hearing aid use.
You can download and print a copy of the ECHO questionnaire and the manual scoring documents from this page. Also you can purchase the ECHO software. The ECHO software provides a way for patients or hearing aid professionals to enter responses directly into an electronic record that can be saved for future use. Responses are scored automatically and can easily be compared to included norms.
