Technology-Assisted Stepped-Care to Promote Adherence in Adolescents with Asthma: A Pilot Study

To examine the feasibility, acceptability, and preliminary efficacy of a technology-assisted stepped-care behavioral intervention to improve adherence in adolescents with asthma. Thirty adolescents (M_age = 14.66, 53% male) with moderate to severe-persistent asthma completed daily adherence monitoring and medication reminders via a mobile app (Step 1). Participants with < 68% adherence during Step 1 received a telehealth behavioral intervention (Step 2). Twenty-six of 30 participants (87%) completed Step 1. Step 2 was indicated for 18 participants and was completed by 17. Participants favorably rated their experience in the study. Improvements in adherence (40-58%, p = .048) and decreases in asthma composite severity scores (CASI 6.08-5.08, p = .023) were observed for the full sample. Technology-assisted stepped-care is feasible and acceptable. Participants demonstrated improved adherence and asthma composite severity scores once they received the appropriate step of the intervention. Future studies should include a control group, a longer time-frame and an intermediate intervention step.
