The cognitive, affective, and behavioral expression of self-stigma among people who use drugs in online substance use communities

A study analyzing Reddit posts by people who use drugs found that self-stigma is a complex phenomenon with behavioral indicators often preceding internalized ones, and identified a four-persona typology among those expressing self-stigma.

The study, which analyzed 72,115 thread-initiating posts from 1,660 English-language users, found that 5.3% of posts from 1,228 users (74.0%) contained self-stigma^[1]. A ten-indicator codebook was developed to identify self-stigma across cognitive, affective, and behavioral domains. Self-labeling and despair/hopelessness were the most common indicators of self-stigma, with 56.0% and 48.5% prevalence, respectively. The study also found that behavioral indicators rarely appeared without internalized ones and often preceded them. A separate analysis using Latent Profile Analysis (LPA) on indicator-level features from 1,174 self-stigma expressors on Reddit yielded a four-persona typology^[2]. Researchers then used sequential Bayesian and recurrent neural classifiers to recover these personas from limited posting histories, and found that persona-matched responses achieved targeted behavioral shifts. However, raters preferred the generic empathy of a persona-neutral baseline. The study's findings suggest that self-stigma is an integrated phenomenon that remains relatively stable over time, but with increasing pessimism about change.
