Interventions
The intervention is offering a free subscription to a mental health app that combines self-guided digital tools with AI-powered support. The app features functions such as an emotional diary and structured courses on topics including managing anxiety and stress regulation. A personalized chatbot, powered by large language models (LLMs) and trained on content grounded in cognitive behavioral therapy, delivers evidence-based strategies such as cognitive restructuring, behavioral activation, and emotion regulation. The chatbot also guides users through these resources using natural, supportive conversations. Participants were randomly assigned to one of two groups: A treatment group offered free access to the app for three months, or A control group, which will receive free access to the app for one month at the end of the study
