# Applying user-centered design to enhance the usability and acceptability of an mHealth supervision tool for community health workers delivering an evidence-based intervention in rural Sierra Leone

## TL;DR

A user-centered design approach was used to improve an mHealth tool for community health workers in rural Sierra Leone, making it more usable and acceptable despite challenges like connectivity.

## Contribution

The study demonstrates how user-centered design can enhance mHealth tool usability in low-resource settings by incorporating feedback from health workers and supervisors.

## Key findings

- The mHealth supervision tool was generally perceived as easy to use by community health workers and supervisors.
- Challenges included connectivity issues, phone charging difficulties, and the need for more comprehensive training and support.
- User-centered design improved the tool's usability and acceptability in a low-resource context.

## Abstract

Mobile health (mHealth) platforms have the potential to increase access to evidence-based interventions in low-resource settings. This study applied a user-centered design (UCD) approach to develop and evaluate an mHealth supervision tool for community health workers (CHWs) delivering an early childhood development intervention in rural Sierra Leone. We engaged CHWs (N=8) and supervisors (N=4) in focus group discussions, user testing sessions and exit interviews to gather feedback on the mHealth supervision tool’s usability and acceptability. Mixed methods findings indicated that the tool was generally well-received and perceived as easy to use, but there were also challenges related to connectivity, phone charging and the need for more comprehensive training and support. Overall, this study suggests that a UCD approach can promote the usability of mHealth tools to support CHWs in delivering evidence-based interventions in low-resource settings, highlighting the importance of addressing contextual challenges and providing adequate training and support to ensure the effectiveness and sustainability of such tools.
