Description of intervention(s) / exposure
This trial is a 2x2 factorial design trial. Groups and descriptions are outlined below.

Hearing Amplification (Group 1 arm 1)
Participants who meet eligibility criteria for the study will be gifted and fitted (at baseline) with personal sound amplification devices which have been approved by both the National Disability Insurance Scheme (NDIS) and Australian Hearing Services Program-Assistive Listening Devices category. The devices will be fitted by a member of the research team or audiologist and will take around 15 minutes. A follow-up appointment will be set for 2 weeks to program the devices based on user experiences. The follow up fitting appointment will also take 15 minutes. During this time participants will also complete baseline (BL) assessments through a self-administered questionnaire with the following assessments:

Patient Health Questionnaire (PHQ-9)
Generalised Anxiety Index (GAI)
Hearing Handicap Inventory for Elderly (HHIE)
Luben Social Network
Loneliness Scale
Function comorbidity
Instrumental Activities of Daily Living (IADL)
Frailty assessment (Fried)
Medical History
Demographics

Total appointment time for participants will be 90 minutes. Follow up assessments including a hearing assessment to monitor adherence will occur at 12 & 26 weeks from baseline.

Behavioural Activation (Group 2 arm 2)
This program will utilise trained research BA therapists who will work directly with participants to promote goal setting and the implementation of action plans designed to reinforce the practice of healthy and rewarding activities. We will adapt our previously developed 8-step behavioural BA program to treat and prevent depression in later life with an emphasis on increasing cognitive, physical and social activity. The 8 one-on-one BA sessions will follow a validated structured program that has been shown to deliver benefits to older adults in the community. These sessions will address:
Recognition of the symptoms of hearing and cognitive loss on activities,
Recognising symptoms of depression & low mood
The value of keeping a diary
Types of activities
Breaking jobs down
The benefits of activities,
Finding ways to be active,
Spotting symptoms of depression
Action plan

The BA therapist will use these principles to encourage participants to enhance their daily routine activities, reduce avoidant behaviours and increase pleasurable behaviours. Activities will be tailored to meet the needs of participants and their living environment. Action plans will be written and include clear step-by step sequences to compensate for cognitive and hearing deficits. The program will be delivered once per week for a total period of up to 12 weeks with each session lasting up to 60 minutes. (whilst there are 8 stages an additional 4 weeks have been provided to account for sickness and other absences).
The BA therapist will work through a self-help workbook with participants supporting them in identifying activities that are meaningful and add value. The workbook provides examples related to breaking activities down and adding them to their daily life to engage them in valued activities and set goals. Each participant will attend a BA appointment with the therapist either face to face or video chat once a week last up to 60 minutes. These sessions will be documented on a fidelity document that will be completed by the BA therapist and reviewed in the next session.
Participants will complete the self-administered questionnaire which includes the assessments outlined in group 1 arm 1 at weeks 12 and 26.

HA & BA (Group 3 arm 3)
Those randomised to both HA & BA will have the personal sound amplification device fitted first and receive the BA workbook at the 2-week fitting check-up appointment. (after completing baseline assessments) Appointments will be made with participants to commence BA within 7 days of completing BL. Follow up hearing and self-administered questionnaire assessments will also take place at 12 and 26 weeks.

Control
Participants will complete a hearing and self-administered questionnaire assessment at baseline, 12 and 26 weeks.
