University students have high anxiety/depression rates, but existing digital mental health tools lack personalization. This pilot study developed GenAI-DBT, a GenAI-based platform for personalized DBT mindfulness training via conversational scenarios. A one-month feasibility study with 45 randomized university students (three groups) will assess engagement, usability, and mindfulness skills. Expected outcomes show GenAI-DBT group has higher engagement and better mindfulness improvements, providing initial evidence for GenAI-based mental health interventions for young adults.
