Mental health apps, VR and AI chatbots promise much, but weak evidence and low engagement hold them back

Study title: The evolving field of digital mental health: current evidence and implementation issues for smartphone apps, generative artificial intelligence, and virtual reality

As of May 2025, this review in World Psychiatry examined how smartphone apps, virtual reality, and generative AI including large language models are being applied to mental health, evaluating evidence across well-being, depression, anxiety, schizophrenia, eating disorders and substance use, and outlining advances in digital phenotyping and generative outputs.

Read the study abstract

The expanding domain of digital mental health is transitioning beyond traditional telehealth to incorporate smartphone apps, virtual reality, and generative artificial intelligence, including large language models. While industry setbacks and methodological critiques have highlighted gaps in evidence and challenges in scaling these technologies, emerging solutions rooted in co-design, rigorous evaluation, and implementation science offer promising pathways forward. This paper underscores the dual necessity of ad…

In brief

The synthesis matters because it links potential clinical benefit to persistent implementation hurdles; it argues positive impact is possible only with correct deployment, while noting that engagement failures, evidence gaps, and equity concerns remain unresolved and require more rigorous placebo-controlled and real-world studies.

Main points

  1. Paper reviews technological advances in digital phenotyping, virtual reality, and generative AI designed to create new outputs such as conversations and images.
  2. Evaluates smartphone app evidence across well-being, depression, anxiety, schizophrenia, eating disorders, and substance use disorders.
  3. Proposes solutions to engagement challenges including human support, digital navigators, just-in-time adaptive interventions, and personalized approaches.
  4. Analyzes implementation issues around clinician engagement, service integration, scalable delivery, and bridging disparities for marginalized populations and low- and middle-income countries.

The problem

Digital mental health tools have run into low user engagement, industry setbacks, gaps in evidence and trouble scaling up, which limit their real-world use and leave equity concerns unresolved.

The rundown

The paper frames digital mental health as moving beyond telehealth to include smartphone apps, virtual reality, and generative AI, with advances in digital phenotyping and models that create conversations and images.

It surveys app evidence across multiple conditions and then details cross-cutting barriers: low engagement, need for clinician engagement and service integration, and equity gaps for historically marginalized groups and low- and middle-income countries, proposing co-design, rigorous evaluation, and implementation science as pathways.
