Digital therapeutics in depression and anxiety: advances and challenges: a literature review

<ns3:p>Background: Depression and anxiety are among the most prevalent mental health disorders globally; however, access to traditional therapy remains limited due to barriers such as cost, geographic constraints, and stigma. Digital mental health interventions (DMHIs), including internet-based cognitive behavioral therapy (iCBT), mobile applications, chatbots, and virtual reality (VR), have emerged as promising alternatives or complements to conventional care.Aim of the study: This review aims to evaluate the effectiveness, advantages, limitations, and future prospects of various digital interventions for depression and anxiety, as well as to discuss their integration into healthcare systems.Material and methods: A comprehensive literature review was conducted, focusing on randomized controlled trials, meta-analyses, and systematic reviews addressing digital interventions for depression and anxiety. The analysis included the efficacy of iCBT, mobile health applications, AI-based chatbots, and VR-based therapies, along with challenges such as adherence, data quality, and personalization.Results: iCBT consistently demonstrates clinical outcomes comparable to those of traditional face-to-face therapy, particularly when guided by a clinician. Mobile applications and chatbots show potential for short-term symptom reduction, especially among younger populations; however, they suffer from variable quality and high dropout rates. VR interventions are effective in exposure therapy, particularly for anxiety disorders, but face barriers including cost and limited accessibility. Hybrid models combining digital tools with professional support enhance adherence and treatment outcomes. Key challenges include user engagement, privacy concerns, and the need for standardization and cultural adaptation.Conclusions: Digital mental health interventions represent valuable complementary tools to traditional therapy, offering increased accessibility and flexibility. Future efforts should focus on improving personalization, regulatory oversight, and integration within healthcare systems to optimize their clinical impact.</ns3:p>
