Summary
Traditional usability questionnaires exclude people with low digital literacy. A new visual tool, co-produced with dementia patients and students, aims to improve digital health technology evaluations for all users.
Area of Science:
- Human-Computer Interaction
- Digital Health
- Health Literacy
Background:
- Traditional usability questionnaires use complex language, excluding individuals with limited digital or health literacy.
- This underrepresentation leads to digital health technologies (DHTs) that may not meet the needs of all users.
- Inaccessible DHTs hinder equitable access and effective use in home settings.
Purpose of the Study:
- To address the gap in evaluating DHTs for individuals with low digital health literacy.
- To co-produce a visually enhanced usability questionnaire suitable for diverse user groups.
- To improve the inclusivity and representativeness of DHT evaluations.
Main Methods:
- A visually enhanced usability questionnaire was developed through co-production.
- Participants included individuals with dementia and students.
- The tool is designed as a card-deck to facilitate conversational evaluation.
Main Results:
- A novel, visually enhanced usability questionnaire was created.
- The card-deck format aims to support engagement and feedback.
- The tool is intended for evaluating DHTs with users of varying digital literacy.
Conclusions:
- The visually enhanced questionnaire may improve representation of users with lower digital health literacy.
- This tool has the potential to contribute to more equitable DHT assessments.
- Further research is required to validate the effectiveness of this visual tool in practice.

451
Assessing the gastrointestinal (GI) system is a complex process that begins with collecting subjective data. This data, collected through patient interviews, provides crucial insights into the patient's health history, perception patterns, and lifestyle habits, all contributing significantly to GI health.
Health Perception Patterns
Health perception patterns offer valuable insights into a patient's lifestyle habits and how they may impact their GI health. These patterns include:
