Research Fellow | University of Oxford | Magdalen College. Head of Oxford EDGE Lab | @edgelab.bsky.social. Clinical Psychologist | Public Health | Statistics | Dynamic Modelling. I study how people transition into and recover from mental disorders.

One of the best parts of academia is mentoring students & witnessing their growth: intellectually, professionally & personally. This privilege also makes the job bittersweet when students complete training. It's been an absolute joy to supervise this wonderful group of students at Oxford EDGE Lab.

A very insightful talk by Vikram Patel on reimagining healthcare for 1.5 billion people last night, followed by a thoughtful conversation with Alan Stein on the challenges and implementation steps required to move toward universal health care coverage in India.

Very excited for this symposium with friends and the opportunity to present some updated analyses on symptom-level timing of improvement during citalopram treatment. Come say hi at #APS26BCN

1: Data-Driven and Computational Approaches for Improving the Characterisation and Treatment of Mental Disorders 👥 With @shirleybwang.bsky.social, @dpmoriarity.bsky.social, @maddyfrumkin.bsky.social, & @marilynpicciri1.bsky.social 📍 Friday 29th of May, 5:30-6:50pm, Room 124, P1 Level

First DPhil paper just published in NMH! ✨ In this Perspective, we examine how social digital environments (e.g., social media) interact with key processes that maintain social anxiety (e.g., self-focused attention, social comparison). 📱🔄🫣 See summary below 🧵

Looking forward to connecting at APS in Barcelona next week! #APS26BCN I'll be presenting & contributing to discussions on (a) Data-driven & computational approaches in assessing & treating MH disorders; (b) Advances in predictive modelling of MH using EMA; & (c) measurement challenges in the field

One of the most challenging issues in studying mental health during COVID-19 was separating the impact of containment policies (lockdowns) from pandemic severity (societal infection rates), as both can contribute to mental distress. In this extensive international effort, we aimed to address this 🧵

I learnt a heck of a lot working on this piece, now out in American Psychologist. Big thanks to all collaborators particularly the mentorship of @omidvebrahimi.bsky.social and @ludvigdb.bsky.social. And of course the amazing resource that is the UKHLS @usociety.bsky.social

Our new article on socioeconomic disadvantage, mental distress & functional impairment is out #OpenAccess in American Psychologist. Led by the brilliant @emkbridger.bsky.social, with J. Maltby, @eikofried.bsky.social, co-supervised by me & @ludvigdb.bsky.social. 🧵 psycnet.apa.org/fulltext/202...

Can LLMs infer depression severity from clinical notes? Here, we evaluate GPT-5.2 on outpatient psychiatry notes to infer depression severity. Results show moderate agreement with PHQ-9 and stronger agreement with clinician chart review (see comments). www.medrxiv.org/content/10.6...

Multi-Criteria Validation of LLM-Inferred Depression Severity from Outpatient Psychiatry Notes

Background Longitudinal measurement of depression severity in outpatient psychiatric care is limited by infrequent standardized assessments. Although psychiatric clinical notes capture illness burden ...

The distinction between grassroots activism and automated influence is collapsing. We typically worry about "bot farms" or "troll factories." But a distinct, more complex threat is emerging. We call it "Cyborg Propaganda."

The Matrix of Coordinated Influence. Traditional frameworks for analyzing online influence focus on the distinction between human and automated actors (Identity Axis) or between spontaneous and coordinated behavior (Articulation Axis). Bot Nets (top-left) rely on synthetic identities and automated scripts. Troll Farms (bottom-left) use human operators to manage fake personas. Grassroots Action (bottom-right) involves verified citizens sharing self-authored views. Cyborg Propaganda (top-right) represents a new paradigm: verified human users disseminating centrally generated, algorithmically generated narratives, effectively ‘hybridizing’ the authenticity of the grassroots with the scale of the botnet.

Bluesky is the new science Twitter, new study by @whysharksmatter.bsky.social and Julia Wester concludes! "Results show that for every reported professional benefit that scientists once gained from Twitter, scientists can now gain that benefit more effectively on Bluesky than on Twitter."

Scientists no Longer Find Twitter Professionally Useful, and have Switched to Bluesky

Synopsis. Social media has become widely used by the scientific community for a variety of professional uses, including networking and public outreach. For

So sad to be missing this! If any of you are lucky enough not to have other commitments late June and are interested in psychological networks, I would highly recommend the summer school (below) organised by @omidvebrahimi.bsky.social (who has the amazing skill of making complex topics accessible!)

An essential take amid article inflation & overburdened reviewers Editors aren't supposed to excessively return manuscripts & outsource decisions to reviewers Many psych journals can learn a lot here from medicine & epi, where these decisions are equally robust, but far more efficient (eg. Lancet)

Chris MacQuarrie @cmacquar.bsky.social · 7mo ago

Peer Review is broken because a generation of Editors were trained that peer review is sacrosanct. Thus we have Editors who are clerks, sending and re-sending manuscripts to reviewers until they are happy. That's not the job. Be an Editor, not a clerk. Use your skill and judgement. Make decisions.
