Mobile apps are touted as helpful tools to track and treat mental health difficulties. Growth in this area is particularly relevant for youth and young adults given the pervasive integration of technology into daily life among younger generations. However, there is limited empirical evidence supporting the usability and/or efficacy of mental health apps for youth and young adults with anxiety disorders. This article offers a review of studies that contained qualitative or quantitative data pertaining to a mobile application for the assessment, prevention, or treatment of anxiety in youth. Apps with a broader scope were included if their findings specifically addressed a reduction in anxiety, as were ecological momentary assessment apps that tracked anxiety. In total, 22 articles met full eligibility criteria, providing data on 14 smartphone apps studied with individuals ages 5-28. This review details each of these apps and associated studies, including their features, efficacy data, and app usability. Results indicated that treatment apps have received moderate to high marks in terms of ease of use, acceptability, and overall satisfaction. Assessment apps were rated as easy to use and had moderate to high satisfaction ratings; however, user engagement declined over time. Passive sensing technology provides the potential for smartphone apps to learn user patterns and identify behavioral indicators that map onto changes in mood. Studies reviewed here provide preliminary support for the use of apps as helpful and accessible tools in the assessment and treatment of anxiety in youth. Future directions and apps to watch are discussed.
Public Significance StatementThis article reviews the evidence base supporting mobile apps for the assessment and treatment of anxiety in youth and young adults. It provides an early guide for psychologists looking for safe, reliable, and effective mobile tools available to supplement existing treatments.
