The COVID-19 pandemic has rapidly accelerated the use of online and remote mental healthcare provision. The immediate need to transform services has not allowed for thorough examination of the literature supporting remote delivery of psychiatric care. In this article we review the history of telepsychiatry, the rationale for continuing to offer services remotely and the limitations of psychiatry without in-person care. Focusing on randomised controlled trials we find that evidence for the efficacy of remotely delivered psychiatric care compared with in-person treatment is of low quality and limited scope but does not demonstrate clear superiority of one care delivery method over the other.
Depression and anxiety are common in adolescents, but most affected will not get any formal help. Digital mental health technologies (i.e. resources and interventions to support and improve mental health) are a potential way to extend the reach and increase adolescents' access to therapies, at a relatively low cost. Many young people can access the internet and mobile technologies, including in low- and middle-income countries. There has been increased interest in integrating technologies in a range of settings, especially because of the effect of the COVID-19 pandemic on adolescent mental health, at a time when services are under pressure. This clinical review gives an overview of digital technologies to support the prevention and management of depression and anxiety in adolescence. The technologies are presented in relation to their technological approaches, underlying psychological or other theories, setting, development, evaluations to date and how they might be accessed. There is also a discussion of the potential benefits, challenges and future developments in this field.
