AI Behavioral Health Project
Due to the subtle behavioral changes that manifest in patients with depression and anxiety, in visual, auditory, and linguistic domains, the problem of depression and anxiety diagnosis lends itself well to a digital, artificial intelligence--based approach. Spanning natural language processing, computer vision, and machine learning for audio analysis, AI-based approaches may be leveraged to detect these nuanced behavioral changes. As a result, the central question of this research is: Can AI methods detect the presence and severity of depression and anxiety?
To explore this question, we collected a novel dataset at the Stanford Family Medicine Clinic. This dataset consists of audio recordings, video recordings, and text transcriptions of casual conversations, like those occurring during intake and rooming at the beginning of a clinic visit. We estimated the presence and severity of depression and anxiety using unimodal and multimodal deep learning models that take as input these audio, video, and text data. We then used saliency analysis to determine the most significant visual and textual features, to illuminate behavioral and digital markers of depression and anxiety that our models use.
We proposed methods of integrating these novel screening tools into clinical care pathways to expand screening for common mental health disorders. This research introduced new AI models for automated mental health screening, generated meaningful clinical insights on behavioral markers of depression and anxiety within our dataset, and charted a path toward AI-enabled, widespread, accessible mental health screening.
