Adolescents often struggle with asthma medication adherence. The ReACT mobile system was developed using teen feedback to improve self-regulation and problem-solving for better inhaled corticosteroid (ICS) use.
Area of Science:
- Digital Health Interventions
- Adolescent Health
- Asthma Management
Background:
- Adolescents with persistent asthma frequently underuse inhaled corticosteroids (ICS), increasing morbidity risk.
- Developing self-regulation and problem-solving skills are crucial for adolescent asthma self-management.
- Mobile health systems can support adherence during developmental transitions in disease management responsibility.
Purpose of the Study:
- Describe the user-centered, evidence-based design process for the Responsive Asthma Care for Teens (ReACT) mobile health system.
- Detail the methods used to incorporate adolescent and caregiver feedback into intervention content development.
- Explain how ReACT aims to enhance self-regulation and problem-solving for improved ICS adherence.
Main Methods:
- User-centered design incorporating individual interviews (n=20) with adolescents (13-17 years) and caregivers.
- National crowdsourcing feedback (n=257) on intervention content.
- Advisory board (n=4) review and refinement of ReACT content and components.
- Iterative development process involving a total of 280 adolescents and caregivers.
Main Results:
- Adolescents identified intrapersonal (e.g., forgetfulness) and external (e.g., routine changes) barriers to ICS adherence.
- 93% of ReACT intervention messages received favorable feedback during crowdsourcing.
- An advisory board refined content and suggested improvements for videos and message flow.
Conclusions:
- Stakeholder engagement through qualitative methods and crowdsourcing was integral to ReACT's development.
- Participant feedback validated ReACT's focus on adaptive, personalized content for self-regulation and problem-solving.
- The iterative process successfully incorporated user recommendations, refining the intervention content.

Asthma: Pathogenesis and Management
Asthma is classified as allergic and non-allergic. Allergens such as dust mites, pollen, and pet dander trigger allergic asthma, while factors like cold air, intense emotions, or exercise can induce non-allergic asthma.
Asthma-II: Pathophysiology and Classification
Additionally, environmental and genetic factors play crucial roles in determining an individual's susceptibility to asthma and the severity of their condition.
Critical processes in asthma pathophysiology include:
