Summary:

Severe psychological distress and mental illness are widespread, affecting over a billion people globally, with extremely diverse presentations. One factor with a strong influence on these presentations is the identity of the individual in distress. Expressions of distress, and how they are perceived by the community, are key to the resources that an individual is able to access. As a result, identity has a strong influence on the pathway that an individual takes from experiencing distress to searching for care. Technology-mediated mental health support (TMMHS) systems, such as helplines or personalized search engine results, have become one such means to find and receive care.

In my doctoral research, I study how engagements with TMMHS systems influence how individuals in distress come to understand their experiences and engage with care, particularly given the impact of identity-based oppression. Identity, particularly marginalized identity, has a strong influence on both experiences of mental illness and on engagements with algorithmic systems. In my work, I thus turn a specific eye to how the personalized design of TMMHS systems might be helpful (such as through matching individuals in need to relevant resources) and how personalization might be harmful (through segregating people away from diverse forms of support or community connection). I leverage mixed methods in these analyses, analyzing biases in TMMHS systems from a technical lens and from the lens of lived experiences of those who use TMMHS systems.

In my completed work, I have used qualitative interviews and computational data (social media posts and online searches) to study the role of identity in how people engage with TMMHS systems. I have found that identity-bound expressions of distress have a strong influence on how people come to understand their illness experience. In my proposed work, I will study gender and racial biases in predictive algorithms for mental health, and conduct algorithm audits of differences (based on identity) in search engine results for mental health resources.

My work is informed by culturally valid frameworks centered around the role of oppression, conflict, and colonialism in how mental health care has been provided throughout history. Through my doctoral work, done in partnership with several mental health advocacy organizations, I contribute an understanding of where identity-based personalization may be helpful in TMMHS systems, and where it may inadvertently deny people care.
