AI Summary

This study addresses the challenge of early detection of mental health conditions—including depression, anxiety, and suicidal ideation—by proposing a non-invasive, multimodal psychological risk assessment framework grounded in social media data. Methodologically, it introduces the first systematic integration of textual, visual, and affective representations, leveraging natural language processing, machine learning, and feature engineering, and validates findings through large-scale survey-based annotation and empirical testing. Key contributions include: (1) development of an interpretable, cross-platform model for mental state identification, achieving robust detection of depressive and anxious states on real-world social media data; (2) empirical validation of social media analytics for clinical auxiliary screening, real-time crisis intervention, and public health policy responsiveness; and (3) advancement of a paradigm shift from individual-level monitoring to population-level mental health governance, thereby providing both methodological foundations and translational pathways for digital mental health services.

Abstract

There is an increasing number of virtual communities and forums available on the web. With social media, people can freely communicate and share their thoughts, ask personal questions, and seek peer-support, especially those with conditions that are highly stigmatized, without revealing personal identity. We study the state-of-the-art research methodologies and findings on mental health challenges like depression, anxiety, suicidal thoughts, from the pervasive use of social media data. We also discuss how these novel thinking and approaches can help to raise awareness of mental health issues in an unprecedented way. Specifically, this chapter describes linguistic, visual, and emotional indicators expressed in user disclosures. The main goal of this chapter is to show how this new source of data can be tapped to improve medical practice, provide timely support, and influence government or policymakers. In the context of social media for mental health issues, this chapter categorizes social media data used, introduces different deployed machine learning, feature engineering, natural language processing, and surveys methods and outlines directions for future research.
