Self-efficacy-based Auditory Rehabilitation to Optimize Real-world Outcomes With Over-the-Counter Hearing Aids: A Pilot Study

The proposed study will use a single-arm pre-post intervention research design to achieve both the aims. Participants will complete two appointments. Assessments in the first appointment will serve as the baseline (unaided). This will be followed by a week of OTC HA use and SEBAR implementation in their natural listening situations and the outcome measures will be completed again in appointment 2 (aided) to reflect the impact of wearing OTC HAs. Scores on the outcome measures will be compared between the unaided and the aided conditions to answer both the aims. Both the appointments in the proposed study will be completed in the shared and dedicated research spaces in the Department of Audiology and Speech Pathology, College of Health Professions at the University of Arkansas for Medical Sciences. The research proposal will be submitted for the university's Institutional Review Board's approval Upon arrival participants will complete the consent process in which the PI will describe in detail all study procedures, risks and benefits of the study, and the lack of negative consequences should the participant choose to withdraw from the study or cease participation during data collection. Once the consent form has been signed, the participant will complete two appointments.

Appointment 1: For each interested participant, a standard audiometric procedure will be completed to confirm their eligibility. Once the eligible participants consent, preliminary measures will be completed. Participants will then complete the unaided baseline outcome measures of hearing aid self-efficacy, willingness to adopt HAs, expected HA satisfaction, current emotional state, and quality of life. At this time, OTC HAs will be fitted to the participants and they will receive the SEBAR. Participants will be instructed to use the HAs for at least 4 hours every day for the next week. Finally, the EMA app will be installed on their phone and its use at home will be demonstrated by the researcher.

Appointment 2: At this appointment, data from the EMA app during the one-week field trial will be stored. HAs will be tested using the Verifit 2 to verify if they are providing the required amount of amplification at the participants' preferred settings. All the outcome measures conducted will be repeated to reflect the outcomes after using the OTC HAs for a week.
