Numbered citations link to the originals at the end. [1][2][3][4][5] Global health agencies estimate that roughly 1 billion people were living with a mental disorder before the COVID-19 pandemic, and that more than 70% of people with mental health conditions in low- and middle-income countries receive no care at all. [1][2] Against that gap, structured digital health software — mood trackers, symptom-monitoring platforms, guided self-help apps and prescription digital therapeutics — is being scaled by ministries of health, clinicians and researchers as a way to expand measurement-based, preventative mental-health support. [1][3][6] ## What 'digital care tools' actually cover The WHO defines digital health broadly as the use of digital technologies for health, including mobile health (mHealth), health information systems and telemedicine, and its Global Strategy on Digital Health 2020–2025 calls on member states to integrate these tools into national health systems. [1] For mental health specifically, the WHO now curates a portfolio of scalable digital interventions — including the self-help programme Step-by-Step for depression and the youth stress-management tool Doing What Matters in Times of Stress — that have been trialled in multiple countries. [2][7] In parallel, regulators have begun clearing 'prescription digital therapeutics' (PDTs): software that delivers evidence-based psychological interventions and is authorised as a medical device. The U.S. FDA has authorised software such as reSET and reSET-O for substance use disorders and Somryst for chronic insomnia, and has published guidance on clinical decision support and software as a medical device (SaMD) to clarify how these products are reviewed. [3][8] ## Why measurement-based care is the anchor 'Measurement-based care' — routinely using validated scales such as the PHQ-9 for depression or GAD-7 for anxiety to guide treatment — has been endorsed by the American Psychiatric Association and multiple systematic reviews as improving outcomes compared with usual care. [4][9] Digital tools make this practical at scale: patients can complete brief questionnaires between visits on a phone, clinicians can see trends over time, and health systems can benchmark quality. [4][6][9] A 2023 review in The Lancet Digital Health of app-based interventions for depression and anxiety found small-to-moderate effect sizes across dozens of randomised trials, with the strongest signals for programmes that combined self-monitoring, cognitive-behavioural content and some human support. [5] Reviews in JAMA Psychiatry have reached similar conclusions for guided internet-delivered cognitive behavioural therapy (iCBT). [10] - **~1B** — people living with a mental disorder pre-pandemic (WHO) [1] - **>70%** — untreated in low- and middle-income countries (WHO) [2] - **25%** — rise in anxiety and depression in year 1 of COVID-19 (WHO) [11] ## Where digital tools are being deployed ### 1. Population-level self-help and prevention WHO's Step-by-Step programme, an e-mental-health intervention for depression, has been evaluated in randomised trials in Lebanon and among Syrian refugees, showing reductions in depressive symptoms compared with enhanced care as usual. [7] Programmes like Doing What Matters in Times of Stress are distributed as free illustrated guides and companion apps and have been recommended by WHO as low-intensity, non-stigmatising entry points to care. [2] ### 2. Health-system measurement-based care Large health systems in the United States, United Kingdom and elsewhere now embed PHQ-9 and GAD-7 questionnaires into patient portals and electronic health records, so that scores are captured at every visit and tracked over time. [4][9] The U.S. Department of Veterans Affairs, for example, has used measurement-based care as a national quality indicator for its mental-health services. [12] ### 3. Prescription digital therapeutics FDA-authorised PDTs such as Somryst (chronic insomnia) and reSET / reSET-O (substance use disorders) deliver structured cognitive-behavioural interventions through a smartphone, with clinician oversight and outcome monitoring built in. [3][8] These products are prescribed like medications and evaluated under the FDA's SaMD framework. [8] > **Not every wellness app is a medical device** _(note)_ > > Most consumer 'mental wellness' apps are not regulated as medical devices and have not been evaluated in controlled trials. WHO and FDA both distinguish between general wellness tools and clinically validated digital therapeutics, and recommend that people with moderate-to-severe symptoms seek professional care rather than rely on an app alone. [1][3] ## The evidence base — and its limits Meta-analyses in The Lancet Digital Health and JAMA Psychiatry consistently show that guided digital interventions can reduce symptoms of depression, anxiety and insomnia, particularly when they include structured cognitive-behavioural content and some form of human support. [5][10] Effects tend to be smaller for fully self-guided apps, and dropout rates in real-world use are typically higher than in trials. [5][10] WHO and NIMH both note that digital tools should complement — not replace — human clinicians, and that equity, data protection and clinical governance must be built in from the start, especially in low-resource settings where connectivity, language and privacy protections vary widely. [1][6] > Digital technologies can strengthen health systems, but their benefits will only be fully realised if they are grounded in ethical principles, human rights and equity. > > — World Health Organization, Global Strategy on Digital Health 2020–2025 [1] ## What good digital care tools have in common - They use validated measures (e.g. PHQ-9, GAD-7) rather than ad-hoc mood scales. [4][9] - They provide feedback loops so clinicians and patients can act on the data, not just collect it. [4][6] - They protect health information under a clear privacy and data-governance framework (GDPR, HIPAA or equivalent). [1][3] - They are transparent about what they are — a self-help tool, a decision-support aid or a regulated digital therapeutic. [1][3][8] - They are evaluated in independent clinical studies, not only in vendor-run pilots.
