Key Findings

  • 01The app achieved an excellent System Usability Scale (SUS) score of 83.4 (percentile rank 90-95).
  • 02Median MARS responses for functionality were high.
  • 03The Net Promoter Score (NPS) of 30 indicated a high likelihood of recommendation.
  • 04Semi-structured interviews revealed the app was perceived as easy to use and helpful, with suggestions for minor improvements in feedback, wording, visuals, and notification timing.

Application

Design takeaway

Design digital tools for specialized user groups with a strong emphasis on intuitive interfaces, clear feedback mechanisms, and opportunities for user-driven iteration.

How to apply

When designing mobile applications for user groups with specific needs, conduct thorough usability testing using established metrics (like SUS and MARS) and gather qualitative feedback for iterative refinement.

Project actions

  • 01When designing an app, think about who will use it and make sure it's simple and straightforward.
  • 02Use surveys like SUS or MARS to measure how easy your design is to use.

Method & Evidence

AimTo assess the usability and acceptability of the TOGETHERCare smartphone application among informal caregivers of cancer patients.
MethodMixed-methods usability study
ProcedureFifty-four informal caregivers were enrolled, with 50 using the TOGETHERCare app for approximately 28 days. Usability and acceptability were evaluated using the Mobile App Rating Scale (MARS), System Usability Scale (SUS), Net Promoter Score (NPS), and semi-structured interviews.
Sample50 participants
ContextHealthcare, mobile health (mHealth), informal caregiving

Variables

IVUsability features of the TOGETHERCare app
DVUsability scores (SUS, MARS), Net Promoter Score (NPS), qualitative feedback themes
CVParticipant demographics (age, gender, ethnicity), duration of app use, type of cancer patient being cared for
04

Strengths & Limitations

Strengths

  • +Employed multiple established usability assessment tools (SUS, MARS, NPS).
  • +Included qualitative data from semi-structured interviews to provide rich context and specific design suggestions.

Limitations

The sample size might be considered moderate for generalizability, and the study was conducted within a specific healthcare context, which could influence user expectations and app usage.

Reliability & validity

The use of standardized scales like SUS and MARS enhances the reliability and validity of the quantitative findings. The qualitative data from interviews adds depth and context, contributing to the overall validity of the study's conclusions.

Think critically

How might the specific context of cancer caregiving (e.g., emotional stress, time constraints) have influenced the caregivers' perception of the app's usability and their willingness to provide feedback?

05

Design Principles

"Prioritize intuitive navigation and clear feedback loops in digital product design to maximize user adoption and satisfaction."

This research highlights the critical need to design digital tools that are not only functional but also intuitive and supportive for often-overlooked user groups like informal caregivers. By prioritizing user-centered design principles, developers can create solutions that genuinely alleviate burdens and improve the quality of care.

06

What This Means for Your Design

This study shows that a new app designed to help people caring for cancer patients was very easy to use and helpful, scoring high marks in tests for usability.

How to use in your project

  • 1.Reference this study when justifying the importance of usability testing for your own design project, especially if it targets a specific user group or addresses a complex need.
