Evaluation of Self-management Education in First Time Hearing Aid Users

Study Overview
=================
Brief Summary
-----------------
The study will assess the impact of a hearing aid self-management intervention in first time hearing aid users compared to standard hearing aid self-management. Namely, the C2Hear multimedia videos, or Reusable Learning Objects (RLOs) will be used as the self-management intervention. A departmental hearing aid booklet (standard clinical care) will be used as the control intervention. The study will determine the role of these RLOs in self-efficacy for hearing aid(s), hearing aid knowledge and readiness for action compared with standard hearing aid self-management education (hearing aid booklet) in groups of first time hearing aid users. Both groups will receive the education at the earliest audiology appointment (hearing assessment), helping to distinguish any impact of earlier education delivery.

Detailed Description
-----------------
Research question: To assess the role of interactive hearing aid self-management education on self-efficacy for hearing aid(s), readiness for action and hearing aid knowledge in first time hearing aid users. Objectives: Primary research question: - Does the early delivery of interactive hearing aid self-management education improve self-efficacy for hearing aid(s) compared with standard care in first-time hearing aid users? Secondary research questions: i. Does the early delivery of interactive hearing aid self-management education improve readiness for hearing aids (their chosen intervention) compared with standard care in first-time hearing aid users? ii. Does the early delivery of interactive hearing aid education improve hearing aid knowledge compared with standard care in first-time hearing aid users? Study design: A single centre, prospective study with two randomised arms; intervention group (access to RLOs in DVD/ or online format, patients' preference) and control (standard hearing aid education booklet). Prospective first-time hearing aid users will be invited to take part in the study at hearing assessment, where they will be randomised to either the control or intervention group. Following 6-8 weeks of independent use prior to receiving hearing aids, study investigators will assess the impact of each education type on individuals self-efficacy for hearing aids, readiness for action and hearing aid knowledge. Comparisons will be made to previous evaluation of the RLOs to allow exploration of the impact of earlier hearing aid self-management education on self-report measures.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: C2Hear RLOs<br>C2Hear RLOs (https://www.youtube.com/C2HearOnline): nine (custom earmould) or eight (open fit hearing aid) multi-media learning clips covering practical and psychosocial components of owning a hearing aid, alongside user testimonials (n= 7). Participants asked to watch all relevant to their prospective hearing aid coupling (custom earmould or open fit), with no limit on number of views. A paper diary documented usage during the study duration. | Behavioral: C2Hear RLOs<br>* Freely available online RLOs<br>|
| Placebo Comparator: Printed hearing aid booklet<br>A 32-page printed A5 colour booklet, designed and written by local Audiology staff, supplied to all prospective hearing aid owners at the study centre as standard care. Same booklet supplied irrespective of hearing aid style (custom/open fit). All content conveyed via text and supporting pictures only. Participants assigned to the placebo comparator were asked to read the booklet once. A paper diary documented usage during the study duration. | Behavioral: Printed hearing aid booklet<br>* Departmental printed hearing aid booklet (standard care)<br>|

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Measure of Audiologic Rehabilitation Self-efficacy for Hearing Aids score (West and Smith, 2007) | Self-reported self-efficacy for hearing aid(s) measured across four-subscales (Basic/advanced handling, adjustment to hearing aids and aided listening). Participants rank confidence in the tasks/behaviours described using an 11-point scale (0%=cannot do this, to 100%=certain I can do this). | Change from Baseline self-efficacy for hearing aids up to 8 weeks | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Hearing aid self-efficacy using Ida Motivational Line Tools (Ida Institute, 2013) | Self-report hearing aid self-efficacy (Ida Line Tool Question 2) determines participants perceived confidence in their ability to use hearing aid(s) using an 11-point visual analogue scale (0 = not at all confident, to 10= very much confident). | Change from Baseline self-efficacy for hearing aids up to 8 weeks | 
| Hearing Aid and Communication Knowledge (HACK: Ferguson et al., 2015) | A 20-item open-ended questionnaire that measures free recall of hearing aid knowledge relevant to practical (n = 12) and psychosocial (n = 8) issues on hearing aids and communication. One point is allocated to each correct response, resulting in a percentage correct for each score. Maximum correct scores are 54; 32 points for practical subscale and 22 points for psychosocial subscale. Higher percentage values represent better knowledge. | Up to 8 weeks | 
| Readiness for hearing rehabilitation (action); Ida Motivational Line Tools Question 1 (Ida Institute, 2013) | Self-report readiness for hearing rehabilitation (action) (Ida Line Tool Question 1) determines participants readiness to use hearing aid(s) using an 11-point visual analogue (0 = not at all important, to 10= very much important). | Change from Baseline readiness up to 8 weeks |
