Anonymity, Verbal Person-Centeredness, and Indentity in Online Recovery and Social Support

Advised by Lana Yarosh

Social support research has investigated reciprocal self-disclosure and when it occurs in practice, but little is known about the effects of reciprocal self-disclosure on support seekers. Inspired by prior work investigating the effects of verbal person centeredness (VPC), we explore the interaction effects of VPC and identity in 12-step recovery, a context that promotes anonymity.

Classifying Verbal Person-Centerdness in Online Health Communities Through Transfer Learning Models

Advised by Lana Yarosh and Andrew High

30 years of research has shown the diverse and impactful effects of verbal person centeredness (VPC) on social support outcomes. Manual classification of VPC has traditionally been tedious and attempts to automate this process have proved not to generalize. We combine multiple datasets from prior work and use modern NLP approaches to classify VPC and evaluate generalizability on an online health community.

Validation of a Classification Model for Naturalistic Expressive Writing

Haiwei Ma | Advised by Lana Yarosh

Expressive writing has been shown to have beneficial health effects. We build on the baselines from prior ML approaches in this space and validate multiple methods for classifying expressive writing beyond accuracy measures using test validity, test-retest reliability, and evaluations of generalizability.

Technology Mediated Disclosure: HIV, Stigma, and Sensitive Self-Disclosure

Fernando Maestre | Advised by Lana Yarosh

Sensitive self-disclosure can be challenging, especially when it involves highly stigmatizing identities. Using a low-fidelity prototype derived from a prior workshop with people living with HIV, we probe participants on using technology to facilitate sensitive self-disclosure in both remote and in-person scenarios.
