referenceThe PRIMATE dataset, introduced at the ACL Clinical Psychology workshop, is designed to assess a language model's ability to consistently estimate an individual's level of depression and provide yes/no responses to PHQ-9 questions.
claimThe T5-XL LLM, when designed to handle questions related to the Patient Health Questionnaire-9 (PHQ-9), produces consistent outcomes regardless of how users phrase their queries because it incorporates clinical assessment methods. In contrast, the FlanT5 LLM produced inadequate responses because its training involved over 1800 datasets, which constrained its capacity for fine-tuning compared to T5.
referenceClinicalT5-large is a generative Language Model with 38 billion parameters, and UExM is a version of ClinicalT5-large enhanced with a PHQ-9-grounded evaluator, which allows for the assessment of how well the model's attention aligns with specific clinical questions.
imageFigure 4 illustrates a task where a generative Language Model takes user input and provides an assessment in natural language within the PHQ-9 context, as referenced in Dalal et al. (2023).
measurementIn a performance comparison on the PRIMATE dataset, the knowledge-powered CREST framework showed an improvement of 6% in PHQ-9 answerability and 21% in BLEURT scores compared to GPT-3.5.
claimClinical practice guidelines, such as the PHQ-9 for depression and GAD-7 for anxiety, can serve as grounded instruction rules for AI models in the mental health field.
claimProcess Knowledge refers to guidelines or instructions created by domain experts, such as the PHQ-9 depression screening tool (Kroenke, Spitzer, and Williams 2001), NIDA’s Attention Deficiency Hyperactivity Disorder Test, and the World Health Organization’s Wellness Indices (Topp et al. 2015).

procedureA study of 500 individuals with varying levels of medical debt used quantitative survey methods to assess correlations between debt size, mental health outcomes (measured by PHQ-9 and GAD-7 scores), and moderating demographic factors including age, income, and education.
