Abstract

Objectives
To investigate factors that influence hearing aid use according to the Theoretical Domains Framework (TDF). The TDF is a behavioral science framework that aids understanding of factors that influence behavior.

Design
Systematic review.

Setting and Participants
People living in the community with dementia and age-related hearing loss who have air conduction hearing aids.

Methods
Systematic literature review following PRISMA guidelines. We searched for studies in 9 databases, including Ovid MEDLINE, Scopus, and OpenGrey. We undertook an interpretive data synthesis by mapping findings onto the TDF. We assessed confidence in the findings according to the GRADE-CERQual approach.

Results
Twelve studies (6 quantitative, 3 qualitative, and 3 mixed methods) were included in the review. The majority of these were rated low-moderate quality. We identified 27 component constructs (facilitators, barriers, or noncorrelates of hearing aid use) nested within the 14 domains of the TDF framework. Our GRADE-CERQual confidence rating was high for 5 findings. These suggest that hearing aid use for people living in the community with dementia and hearing loss is influenced by (1) degree of hearing aid handling proficiency, (2) positive experiential consequences, (3) degree of hearing aid comfort or fit, (4) person-environment interactions, and (5) social reinforcement.

Conclusions and Implications
Hearing aid interventions should adopt a multifaceted approach that optimizes the capabilities of people with dementia to handle and use hearing aids; addresses or capitalizes on their motivation; and ensures their primary support network is supportive and encouraging of hearing aid use. The findings also emphasize the need for further high-quality research that investigates optimal hearing aid use, influencing factors, and interventions that support hearing aid use.
