Primary outcomePrimary: Number of Participants Completing 4-week Study Period — 10; 11 Participants
Summary
The purpose of this 4 week pilot study is to test the use of a mobile application (also commonly referred to as an app) designed to help increase self-management strategies among youth that have asthma and obesity. The data obtained from this study will facilitate refinement of the app and interventional approaches for a future larger scale study to increase youth self-management of their clinical conditions, symptom management, and health maintenance as they transition to adulthood.
