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

This research will contribute to fundamental knowledge about how young adults with asthma perceive their personal health risks to wildfire smoke, minimize their risk, and improve their health. The investigators will compare young adults who use 'Smoke Sense,' an EPA-developed smart phone application (app), with young adults who use the app plus engage in preventive activities, with young adults who do not use the app. Study aims are to: 1. Establish the feasibility (recruitment, enrollment, retention rates), acceptability (intervention engagement, fidelity, usability, attitude) and barriers and facilitators of adopting the technology of the Smoke Sense interventions and use of portable devices in young adults with asthma; 2. Explore the preliminary impact of the Smoke Sense interventions on lung function and asthma control. These primary outcomes will be assessed using objective measures (spirometry) and validated, self-report tools. Secondary outcomes will be anxiety, exposure reduction behaviors (e.g. stayed indoors, wore a mask), and symptom mitigating behaviors (use of medication, unscheduled health care appointments), measured via self-report and a Global Positioning System device. Outcome by group will be summarized. Preliminary evidence of treatment effect and its variance will be examined for a future clinical trial; 3. Explore potential mediators (medication adherence, self-management skills, stress) and moderators (asthma severity/control) of the interventions to asthma outcomes. The long-term goal is to minimize asthma exacerbations from exposure to wildfire smoke. The long-term goal of the study is to minimize asthma exacerbations from exposure to wildfire smoke.
