Developing a prototype web-based decision aid for adults with hearing loss

Area of Science:

• Audiology
• Health Informatics
• Human-Computer Interaction

Background:

• Adults with hearing loss require accessible resources for making informed health decisions.
• Existing decision support tools may not adequately address the specific needs of individuals with hearing loss.

Purpose of the Study:

• To develop a prototype of a web-based decision aid for adults with hearing loss.
• To ensure the decision aid aligns with the International Patient Decision Aid Standards (IPDAS).

Main Methods:

• A survey involving 153 participants (adults with hearing loss, family members, professionals) identified priority content.
• A think-aloud process with 12 participants evaluated an initial version of the decision aid.
• Iterative development based on user feedback regarding content, usability, and design.

Main Results:

• 26 out of 38 potential items were prioritized for inclusion in the initial decision aid.
• User feedback highlighted the need for improved graphics and enhanced ease of use.
• A prototype web-based decision aid was developed incorporating participant recommendations.

Conclusions:

• The developed methodologies are suitable for creating decision aids for adults with acquired hearing loss.
• User-centered design is crucial for effective decision support tools in audiology.
• Further development should focus on incorporating visual elements and optimizing user experience.
