Negative Sentiment and Mental Health Discourse in Reddit Communities on Dating Apps

This study examines how emotional tone and mental-health discourse influence participation in Reddit communities focused on dating apps. We analyzed more than 378,000 posts, collected between July 2022 and June 2025, from five major subreddits dedicated to dating apps, including r/Tinder, r/Bumble, r/hingeapp, r/OkCupid, and r/onlinedating. Posts were processed with transformer-based sentiment analysis and through a BERT-based classifier (PsychBERT) that allocated content into mental health categories such as anxiety, depression, social anxiety, loneliness, and mental illness. Three key patterns emerge. First, the overall tone of discussion is persistently negative and becomes increasingly so over time, suggesting a gradual deterioration in the emotional climate of these communities. Second, mental-health framing is widespread but uneven: social anxiety is especially prevalent, while explicit references to depression or mental illness appear less frequently and decline relative to neutral content. Third, community responses show a selective amplification of vulnerable disclosures. Posts that explicitly reference loneliness, depression, or anxiety receive markedly higher community support, and emotional intensity itself predicts greater visibility through Reddit’s scoring system. These findings demonstrate how dating-related online forums do more than host individual narratives: they actively shape the collective emotional environment by rewarding certain kinds of disclosures. The results highlight an interplay between platform design, community norms, and patterns of self-expression that can validate distress but also reinforce negative affect at scale.
