Identifying Stigma Phenotypes in Social Media Narratives of Substance Use: Observational Study.

ABSTRACT:

Background

Individuals with substance use problems experience stigma in different contexts. Identifying characteristic situations in which stigma occurs or manifests-stigma phenotypes-can serve as important leverage points for future intervention.

Objective

This paper aims to (1) identify stigma phenotypes expressed in social media narratives related to substance use stigma and (2) explore the similarities and differences between the stigma phenotypes from a social ecological perspective.

Methods

We collected Reddit posts pertaining to 3 substances-alcohol, cannabis, and opioids. We performed feature engineering using a combination of content analysis, machine learning, and keyword-based methods to predict variables at different levels of the social ecological framewo
