The developmental process for this application will begin with modification of existing technology, which will be followed by conducting focus groups with the intended target population as well as with physicians, primary care staff, and health administrators, respectively, in order to enhance the adoptability of the intervention by including application functions and interface design that is sensitive to the needs of all stakeholders. Small scale testing with members of the target population will be used to further refine the application and produce a beta version for use in a pilot randomized controlled trial.
