The effective management of chronic asthma requires long-term adherence to both pharmacotherapy and optimal self-management practices. The use of mobile applications (apps) offer a promising and cost-effective platform to support the self-management of asthma. However, students as consumers may not always be sufficiently knowledgeable to select the best app to link with the management of their condition. If school psychologists become familiar with apps, they may be better positioned to provide guidance to students about app selection and how to identify apps that include appropriate behaviour change techniques (BCT). Accordingly, the overall aim of this study was to present a method by which school psychologists could identify quality apps for the purpose of supporting students who need to self-manage chronic asthma. A directed content analysis was used to evaluate asthma apps, based on behaviour change content and app quality. A systematic selection process yielded a total of 36 apps (26 from iTunes, 12 from Google Play) that were evaluated using two published rating measures. Overall, apps contained limited BCTs and a low level of quality health information. Conversely, apps with higher quality health information utilised a larger range of BCTs than lower quality apps. It was concluded that while apps designed to support the management of asthma appear to be a potentially valuable addition to traditional interventions, the technology is still in its infancy, and school psychologists should be aware of the limited behaviour change content, age appropriateness of apps, and whether the health information provided is evidence-based.
