Designing electronic Personal Health Records (ePHR) with a strong emphasis on ease of use, clear visual elements, and efficient information retrieval significantly increases adoption intentions among elderly users. This user-centred design research insight is drawn from a 2026 study published in Digital Health. Using Quantitative survey and structural equation modeling with 420 participants, researchers explored how this design variable affects real-world outcomes. The key design takeaway: Designers should prioritize intuitive navigation, large and clear fonts, high-contrast color schemes, and straightforward operational flows when developing ePHR systems for older adults, as these elements directly impact perceived ease of use and adoption.

Key Findings
- 01Perceived ease of use (PEOU) was the strongest predictor of behavioral intention (BI) to adopt ePHR.
- 02Platform features, font clarity, color/icon design, operational cognition, and feedback perception significantly influenced PEOU, PU, and BI.
- 03Information retrieval features had a lesser impact on BI compared to other UI elements.
Application
Design takeaway
Designers should prioritize intuitive navigation, large and clear fonts, high-contrast color schemes, and straightforward operational flows when developing ePHR systems for older adults, as these elements directly impact perceived ease of use and adoption.
How to apply
When designing any digital interface for an aging demographic, conduct user testing specifically focused on ease of navigation, readability of text, and clarity of interactive elements. Iterate designs based on feedback related to these aspects.
Project actions
- 01When researching user needs, specifically ask about difficulties with current digital tools.
- 02Test prototypes with older users and observe their interactions to identify usability issues.
Method & Evidence
Variables
Strengths & Limitations
Strengths
- +Utilizes an established theoretical framework (UTAUT) extended with relevant UI factors.
- +Employs a robust statistical method (SEM) for data analysis.
- +Investigates a critical and growing area of digital health.
Limitations
The sample size might be limited in its diversity of older adults (e.g., varying levels of tech literacy, different health conditions). The study's focus on a specific country may limit broader applicability.
Reliability & validity
The use of SEM suggests a rigorous statistical approach, contributing to the study's internal validity. The broad range of UI factors and user perceptions examined enhances the construct validity. Reliability would depend on the consistency of measures used in the questionnaire.
Think critically
How might the cultural context of China, as studied, influence the specific UI elements that are most effective for older adults, and how could these findings be adapted for a different cultural setting?
Design Principles
"For digital health interfaces targeting older adults, prioritize perceived ease of use through clear visual hierarchy, legible typography, and intuitive interaction patterns."
As the global population ages, creating accessible and user-friendly digital health solutions is paramount. This research demonstrates that thoughtful UI design is not merely an aesthetic consideration but a critical driver of technology adoption, particularly for demographics who may face unique challenges with new digital tools.
What This Means for Your Design
Making health record apps easy to use and understand, with clear text and simple buttons, makes older people more likely to use them.
How to use in your project
- 1.Use the findings to justify design decisions related to interface elements like font size, button placement, and navigation flow in your design project.
- 2.Reference the study when discussing the importance of user-centred design principles for specific user groups.

Paragraph starter
This design project acknowledges the critical role of user interface design in technology adoption, particularly for demographic groups such as the elderly. Research by Zhang et al. (2026) highlights that perceived ease of use, influenced by factors like font clarity and intuitive operation, is a primary driver for the acceptance of electronic health records among older adults. Therefore, design decisions for this project will prioritize clear visual hierarchy, legible typography, and straightforward navigation to ensure accessibility and encourage user engagement.
