A Mixed-Methods Evaluation of a Novel, Augmented Reality Educational App for Asthma

Background: Asthma education is an important component of asthma management and control. Technology-based approaches via mobile health applications have been studied in many different diseases, including asthma. Innovative educational approaches, such as augmented reality (AR) serious games, may be effective and appealing to caregivers of children with asthma, with the goal of improving asthma control. Objectives: The purpose of this mixed-methods study was to assess the usage, acceptability, and feasibility of an AR component to the CHANGE-Asthma (Clinic, Home, and On-the-Go Education for Asthma) app, an educational bundle using serious games to support self-directed learning. Methods: This was an explanatory, sequential mixed-methods study. Quantitative data consisted of usage time within the app. Qualitative data consisted of semi-structured interviews evaluated via thematic analysis to identify recurring themes related to their experiences. Results: Time spent within the app decreased after the first week. The mean total time spent within the app was 8.6 min over an average of 14 weeks (range 9–19 weeks). Themes identified from thematic analysis included perceptions of the app as helpful to both participants and others with AR supporting asthma management skills. Some users reported technological challenges with using AR. Conclusions: Despite low usage of the CHANGE-Asthma app, caregivers held an overall positive view of the app and its educational features. AR was well received as a tool for deliberate practice but limited by difficulty with utilizing the AR feature on their personal devices.
