Participatory Mobile App Development with Chorus


Participatory Mobile App Development with Chorus



The Chorus participatory mobile health framework is an innovative, user-friendly web application to enable a broad array of stakeholders (non-techy people, community partners, developers, and content experts) to rapidly and collaboratively create, in as little as a few minutes, a broad range of automated text messaging (SMS), interactive voice (IVR), and mobile web applications using a simple and accessible visual interface. It lowers the financial, technical and time constraints of traditional mobile application development and the accessible visual interface enables direct engagement of end users in the development process. This direct engagement enables a participatory approach to mobile intervention development- an approach that is iterative, agile, and results in apps tailored to individual user or community needs.

Potential use cases are broad, including research data collection, educational games, health status monitoring, and others. Additionally, rapid and low cost development allows for new types of application to be created. For example, 'just-in-time' applications can be created to respond to specific, time-sensitive needs such as public health emergencies, disasters, or other events where customized interventions need to be created and deployed in a critical time period.

We have used it through the Center for Health Services and Society at UCLA in a range of projects including 1) engaging community partners in co-creating a resiliency-based text messaging app; 2) participatory development with parents, teachers and students within LA Unified School District of a mobile app to address coping with trauma; and 3) supporting patient-centered care through patient and provider co-created mobile apps to support treatment in the psychiatry partial hospitalization programs.

In this session we will review the Chorus participatory mobile framework, key principles in ‘participatory mobile intervention development’ and case examples from ongoing projects.
