Auditory disabilities, individual fitting targets, and the compensation power of hearing aids

AVAB, COSIResumé
There is lack of a systematic approach how to select an adequate hearing aid and how to evaluate its efficacy towards the personal needs of rehabilitation. The goal of this study was to examine the applicability and added value of two widely used self-reporting questionnaires (COSI and AVAB) in relation to the evaluation of hearing aid fitting. We analysed responses from 740 subjects who filled in the questionnaires pre and post hearing aid fitting. Results show a moderate to strong correspondence between COSI scores for overall degree of change and final ability. Most COSI responses are at or near the maximum possible score and show slight differences in overall scores considering the effect of hearing aid experience or hearing loss. AVAB results reveal a more refined evaluation of the hearing aid fitting. Combining the advantages of both methods results in a profound evaluation of hearing aid rehabilitation. Our results suggest that both methods should be used complementary, rather than separately.
