Measure
Audiologist-Based
In this group, the audiologist-based fitting will be used to provide hearing aids. Audiologist-based fitting: Hearing aids will be fitted by audiologists using established procedures.
Service-Only
In this group, hearing aids that have minimum amplification will be fitted by audiologists. Service-only Fitting: This intervention group is designed to explore the contribution of amplification devices in hearing aid intervention, which consists of devices and services. In this intervention group, audiological services plus hearing aids that provide minimum amplification will be provided. Specifically, patient participants in this group will receive audiological services (e.g., counselling and education), except that the hearing aids will be set to provide no amplification other than what is needed to overcome any sounds that are dampened by the earpieces.
Device-Only
In this group, hearing aids will be provided with minimum services from audiologists. Device-only fitting: This intervention group is designed to explore the contribution of amplification devices in hearing aid intervention, which consists of devices and services. The patient participants in this intervention group will have minimum services regarding the pre-fitting, selection, and orientation of the hearing aids. The participants will have a hearing evaluation, including pure-tone audiometry. The audiologist will select the amplification characteristics and non-custom ear piece based on the audiogram. The audiologist will then briefly orient the participant on how to use the hearing aids and counsel on how to optimize their performance.

The IADL was developed to assess independent living skills, such as feeding, dressing, and food preparation. The score ranges from 0 (low function) to 8 (high function). Participants complete this measure pre-intervention and at 6 weeks post-intervention. The change in scores between pre- and post-intervention are reported, with score changes ranging from +8 (indicating a benefit from hearing aids) to -8 (indicating a detrimental effect of hearing aids).

Caregiver burden will be measured using the ZBI, which is a 22-item questionnaire. The ZBI measures self-reported burden in terms of the degree (from 'never' to 'almost always') to which the caregiver experiences physical, psychological, emotional, social and financial problems as a result of their care-giving role. The score ranges from 0 (little or no burden) to 88 (severe burden). This measure is completed pre-intervention and at 6 weeks post-intervention. The change in scores between pre- and post-intervention are reported, with score changes ranging from -88 (indicating a benefit from hearing aids) to +88 (indicating a detrimental effect of hearing aids).

The HHIE and HHIA are questionnaires designed to measure perceived hearing handicap. For subjects order and younger 65 years old, the HHIE and HHIA will be used, respectively. The score ranges from 0 (no handicap) to 100 (more handicap) (i.e., lower scores mean less handicap). Participants will complete this questionnaire pre-intervention and at 6 weeks post-intervention. The change in scores between pre- and post-intervention are reported, with score changes ranging from -100 (indicating a benefit from hearing aids) to +100 (indicating a detrimental effect of hearing aids).

The ADRQL was developed to assess health related quality of life in people with Alzheimer's disease using assessments from family caregivers or professional staff. The score ranges from 0 (worst situation) to 100 (best situation). Participants complete this measure pre-intervention and at 6 weeks post-intervention. The change in scores between pre- and post-intervention are reported, with score changes ranging from +100 (indicating a benefit from hearing aids) to -100 (indicating a detrimental effect of hearing aids).
