Longitudinal Analysis of Self-Stigma: A Cognitive-Affective-Behavioral Characterization of Reddit User Timelines

This ongoing research contributes to a longitudinal analysis of internalized self-stigma among people who use drugs on Reddit. The study involves benchmarking 7 large language models to select the optimal classifier (F1 = 0.856), engineering prompts for 10 stigma indicators, and performing backward evaluation by human-labeling misclassified cases to refine decision boundaries (macro-avg F1 = 0.864). The work also includes participating in open coding for codebook development.

This research is conducted in collaboration with Prof. Rezvaneh “Shadi” Rezapour at Drexel University.
