(new paper) 📑 A large-scale study of Premenstrual Dysphoric Disorder in online settings: looking at reported symptoms, treatments, and comorbidities on Reddit. Collaboration with @sreblet.bsky.social , @petrakn.bsky.social and Julie Riddell 🔗 www.nature.com/articles/s41... #PMDD #MentalHealth

👀 I’ll be presenting this work this week at @ic2s2.bsky.social (Thu, 11:00 AM · Social Media & Networks). If you’re there & interested, let’s connect! #IC2S2 N/N

💡 The perception of mental health disorders is continually shaped by digital spaces. They should not be taken as mere anecdotes but an essential part of the larger picture into understanding psychopathology. 7/N

🚨 Neither diagnostic criteria nor online health communities give a holistic view of psychopathology. But together they offer complementary perspectives: • one shaped by clinical expertise & tradition • the other by lived experience & modern challenges 6/N

📊 Reddit vs Diagnostic Criteria Only 6% of links are present in both networks, yet broader clusters partly align. Some results echo dimensional frameworks like HiTOP: 🌀 Internalizing cluster: depression, anxiety & OCD 🌀 Thought disorders cluster: psychosis, trauma & personality disorders 5/N

We also observe (with some caveats) that addiction recovery communities (alcohol, opioids, impulse-control) show negative ties 🚫 to much of the network, which may reflect symptom-focused isolation & (self‑)stigmatization despite known comorbidities. 🟥 See here: tinyurl.com/reddit-psych... 4/N

🧠 Trauma, dissociation & avoidance emerge as central transdiagnostic hubs. 🛡️ Entire ICD‑10 categories: psychotic (F2), mood (F3) and personality disorders (F60) have fuzzy boundaries, linking more across than within categories. 🌐 Network of positive associations: tinyurl.com/reddit-psych... 3/N
