Online gambling forums as a potential target for harm reduction: an exploratory natural language processing analysis of a reddit.com forum.
Article in Harm reduction journal, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
objectivesGlobally, there has been a rapid increase in the availability of online gambling. As online gambling has increased in popularity, there has been a corresponding increase in online communities that discuss gambling. The movement of gambling and communities interested in gambling to online spaces presents new challenges to harm reduction. The current study analyses a forum from a popular online forum hosting website (reddit.com) to determine its suitability as a source for data to inform gambling harm reduction in online spaces.
methodsThe current study provides an exploratory analysis of 1,141 unique posts and 11,668 comments collected from the online forum r/onlinegambling. The dataset covers posts and comments from August 5, 2015, to October 30, 2023. Natural language processing (NLP) techniques were used to identify common terms and phrases, identify topics with high rates of participant engagement and perform a sentiment analysis of posts and comments.
resultsSentiment analysis results showed that the majority of posts and comments were positive, but there were substantial numbers of negative and neutral content. Positive content was often congratulatory and focused on winning, neutral posts more commonly focused on practical advice, and negative posts were more commonly concerned with avoiding operators perceived as illegitimate by forum participants.
conclusionsResults from this study show that there is a varied and robust discussion of different aspects of gambling on r/onlinegambling. Our exploratory analyses suggest that this reddit forum provides important information on how users communicate motivations to gamble, interpretations of gambling experiences, and define potential harms related to gambling online as well as how to avoid or remedy those harms. Reddit forums discussing gambling have great potential for future research interested in more specific aspects of harm reduction and prevention related to online gambling, particularly when using NLP techniques.
