Who can join

Ages 12 to 17 · All sexes

Inclusion Criteria:

* At least 12 and less than 18 years at enrollment
* Established mild, moderate, or severe persistent asthma with a diagnosis verified by clinic physicians
* Speak English
* Not planning on moving out of the Tampa Bay area during the trial period
* Must have a suitable iPhone or Android device available to use with the app

Exclusion Criteria:

* Having mental or other development disorder that may make self-management of a chronic condition difficult

* Having participated in the app development phase of the funded project

About the study

The primary goal of this project is to determine the feasibility, acceptability, and adherence of a smartphone application for improving asthma self-management in a pilot randomized controlled trial (RCT). The app is specifically designed to appeal to adolescents. Adolescents with persistent asthma will be randomized to receive: 1) standard-of-care or 2) the self-management app in addition to standard-of-care. Feasibility will be assessed by the ability to recruit and retain subjects, technical barriers to implementation, and the appropriateness of the intervention among adolescents and providers. The acceptability of the intervention will be determined by appraising perceived usefulness, entertainment, and ease of use of the app. Adherence to usage of the app over a 6-month period will be assessed by examining the frequency of app usage and the features that were used, and the extent of data regarding self-management that was entered. A secondary objective is to obtain preliminary estimates of effectiveness of the app on clinical outcomes (ACT score, spirometry, CHSA-C, exacerbations, and medication adherence) relative to standard-of-care. It is hypothesized that the app will result in a high level of adherence and will be a feasible and acceptable intervention to improve self-management among adolescents with persistent asthma.
