Abstract

Support, a multimodal LLM-driven application, offers psychological help to undergraduate students facing stress and relationship issues. Unlike tools that only deliver basic or superficial responses, Support incorporates four therapeutic orientations—Cognitive Behavioral Therapy, Solution-Focused Brief Therapy, Person-Centered Therapy, and Marriage and Family Therapy. It achieves this by fine-tuning MentaLLaMA-chat-7B with specialized psychological datasets, creating a unique AI companion capable of engaging through both text and voice. The system features four counseling dialogue styles within an integrated framework that evaluates depression and suicide risk, also incorporating safety measures and privacy protections. Guided by design science and responsible AI principles, Support connects innovation to human well-being as an information-systems artifact. The metrics and evaluations verify distinct therapeutic styles but also identify areas for improvement. Support demonstrates the potential of digital innovation to enhance youth emotional well-being, emphasizing responsibility and safety in human-AI interactions.
