Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
HearChoice: an online, modular, patient decision-support intervention for adults with hearing loss. Participants will independently access HearChoice via their smartphone, tablet, or computer web browser by following a link. HearChoice is designed to provide a step-by-step guide to decision-making about hearing healthcare, including background information about hearing loss, the importance of management, and guidance about options. HearChoice is presented using written text, images, interactive quizzes, and videos. HearChoice is designed so that participants can work through it at their own pace, and they may spend as little or long as they choose using HearChoice. Time spent on HearChoice will be monitored using website analytics. HearChoice will be made available to the participants for 3 months after they consent to participate, as we anticipate participants may wish to access the intervention more than once.
Intervention code [1] 328786 0
Behaviour
Comparator / control treatment
Hearing Loss Option Grid: hearing technology options. Participants will independently access the option grid via their smartphone, tablet, or computer web browser by following a link. The option grid is designed to provide a framework for decision-making about technology-based hearing management options, presented using written text. Participants will be allowed to review the option grid at their own pace, and they may spend as little or long as they choose using the option grid. Time spent on the option grid will be monitored using website analytics. The option grid will be made available to the participants for 3 months after they consent to participate, in line with what we plan to do for the HearChoice intervention.

Efficacy
Statistical methods / analysis
Demographic and hearing characteristics of the intervention and control groups will be described at baseline.

Differences between groups will be evaluated at each timepoint using independent samples t-tests. The primary analysis will evaluate whether there is a difference between the intervention and control groups up to 5 days post intervention.

Analysis of variance will be used to compare change over time on each outcome measure between the intervention and control groups.

Additional analyses will be performed to explore the impact of demographic and hearing characteristics on each outcome over time between groups.
