Depression is a major public health concern in the U.S. and globally. While successful early
identification and treatment can lead to many positive health and behavioral outcomes,
depression, remains undiagnosed, untreated or undertreated due to several reasons,
including denial of the illness as well as cultural and social stigma. With the ubiquity of social
media platforms, millions of people are now sharing their online persona by expressing their
thoughts, moods, emotions, and even their daily struggles with mental health on social
media. Unlike traditional observational cohort studies conducted through questionnaires
and self-reported surveys, we explore the reliable detection of depressive symptoms from
tweets obtained, unobtrusively. Particularly, we examine and exploit multimodal big (social)
data to discern depressive behaviors using a wide variety of features including individuallevel
demographics. By developing a multimodal framework and employing statistical techniques
to fuse heterogeneous sets of features obtained through the processing of visual,
textual, and user interaction data, we significantly enhance the current state-of-the-art
approaches for identifying depressed individuals on Twitter (improving the average F1-
Score by 5 percent) as well as facilitate demographic inferences from social media. Besides
providing insights into the relationship between demographics and mental health, our
research assists in the design of a new breed of demographic-aware health interventions.
