Weight Management Apps Exhibit Significant Accessibility Gaps for Users with Disabilities

Top-rated weight management mobile applications demonstrate substantial accessibility barriers, particularly for individuals with visual and dexterity impairments.

International Journal of Environmental Research and Public Health · 2021

01

Key Findings

  • 01Users with visual impairments reported the lowest accessibility ratings and encountered the most significant challenges.
  • 02Users with dexterity impairments experienced considerable accessibility-related difficulties.
  • 03Users with cognitive impairments reported milder difficulties and a higher tolerance for issues.
02

Application

Design takeaway

Incorporate robust accessibility features, such as screen reader compatibility, adjustable font sizes, and alternative input methods, from the initial design stages of mHealth applications.

How to apply

When designing or evaluating mHealth apps, conduct user testing with individuals representing diverse abilities to identify and rectify accessibility barriers.

Project actions

  • 01When choosing an app to analyze, consider its target audience and potential accessibility challenges.
  • 02When testing an app, think about how different users might interact with it differently.
03

Method & Evidence

AimTo systematically evaluate the accessibility of popular mHealth apps for individuals with vision, dexterity, and cognitive impairments.
MethodUser testing with assessment instruments
ProcedureThree top-rated weight management apps were evaluated by nine participants representing three disability groups (vision, dexterity, cognitive impairment) using established assessment tools.
Sample9 participants
ContextMobile health (mHealth) applications for weight management

Variables

IVType of disability (vision, dexterity, cognitive impairment)
DVApp accessibility ratings, reported challenges, tolerance for issues
CVSpecific weight management apps tested, assessment instruments used
04

Strengths & Limitations

Strengths

  • +Systematic approach to evaluation.
  • +Inclusion of multiple disability groups.

Limitations

It can be challenging to recruit a diverse range of participants for user testing.

Reliability & validity

The use of established assessment instruments contributes to validity, while the pilot nature and small sample size may limit generalizability and thus reliability across different contexts.

Think critically

How might the design choices in these weight management apps inadvertently create barriers for specific user groups, and what are the ethical implications of releasing products with such limitations?

05

Design Principles

"Universal design principles should be applied to ensure digital health tools are usable by the widest possible range of users, regardless of ability."

As digital health solutions become increasingly central to wellness, overlooking accessibility for diverse user groups can exclude a significant portion of the population. Designers must proactively integrate universal design principles to ensure equitable access and usability for all potential users.

06

What This Means for Your Design

Popular health apps are hard for some people to use, especially if they can't see well or have trouble with fine motor skills.

How to use in your project

  • 1.You can use this research to justify why testing with users with disabilities is crucial for your design project's success.
