Exploring The Potential of Large Language Models for Assisting with Mental Health Diagnostic Assessments
This research evaluates the potential of Large Language Models (LLMs) to enhance mental health diagnostic assessments. By analyzing their ability to mimic standard clinical procedures for Major Depressive Disorder (MDD) and Generalized Anxiety Disorder (GAD) using tools like PHQ-9 and GAD-7, the study explores both prompting and fine-tuning strategies. Findings demonstrate that LLMs can achieve high agreement with expert-validated diagnoses, offering a promising path to alleviate provider workload and improve access to mental healthcare.

The study meticulously examines two primary methodologies for leveraging LLMs in mental health diagnostics: prompting and fine-tuning. Prompting involves guiding LLMs with specific instructions and examples, utilizing models like GPT-3.5, GPT-40, llama-3.1-8b, and mixtral-8x7b. Fine-tuning, on the other hand, adapts models like Mentalllama and DiagnosticLlama to deeply embed diagnostic procedures, aiming for greater adherence to clinical standards.
Performance was evaluated using hits@k ranking and standard classification metrics (accuracy, precision, recall, F1-score) against expert-validated ground truth. While LLMs initially struggle in zero-shot settings, their performance significantly improves with few-shot prompting and fine-tuning, nearly matching expert clinicians. The introduction of specialized models like DiagnosticLlama demonstrates a pathway to highly accurate, process-adherent AI assistance in mental healthcare.
