Promoting Risk Reduction Among Young Adults With Asthma During Wildfire Smoke Events (TRAK)

Smoke Sense is a smartphone application (app). Smoke Sense participants will be asked to establish a profile which includes demographics, baseline health information and current beliefs about smoke and air pollution. In the Symptoms \& Smoke Observations tab, participants are asked to report their weekly observations of smoke, health symptoms, and exposure reduction behaviors. In the Fire \& Smoke Near Me tab, participants review the most recent AQ data measured at an AQ monitoring sites. Participants are asked to complete the AQ 101 module which test knowledge of AQ facts and provides correct answers. Badges are awarded for accomplishments within the app to promote certain desired behaviors: completing a user profile, launching the app weekly to check local AQ, reporting smoke and symptom observations, expanding AQ knowledge with AQ lessons, and exploring the map. Finally, participants can engage with other users by viewing cumulative statistics of symptoms and smoke observations.

Participants randomized to the Smoke Sense Plus intervention will be asked to do everything that the Smoke Sense intervention group does on a weekly basis, as well as: 1) Receive weekly push notifications that remind them to, for example, review their asthma action plan, refill any expired medications, take their daily controller medication, identify a clean air space in their home and community, 2) Monitor their lung function weekly via mobile spirometry, and 3) Subscribe to a social network to share strategies to minimize exposure.
