New paper from our team: Can ML identify which adolescents benefit most from school-based mindfulness? In 8,376 students (MYRIAD trial), models detected statistically significant but clinically negligible differential effects (d ≈ .07–.08). Precision prevention is hard...

I am thrilled to share my new first author pub in JAD! 🥳 We found minority stress was associated with concurrent and future experiences of defeat, and defeat was associated with prospective minority stress in sexual minority college students reporting SI. authors.elsevier.com/a/1meFzbXYj0...

⚠️ Despite all the hype, chatbots still make terrible doctors. Out today is the largest user study of language models for medical self-diagnosis. We found that chatbots provide inaccurate and inconsistent answers, and that people are better off using online searches or their own judgment.

We should no longer trust data collected on MTurk link.springer.com/article/10.3... My guess is that other online data is going to drop in quality due to LLMs. This is going to be an existential crisis for the behavioral sciences.

It’s grad school application season, and I wanted to give some public advice. Caveats: -*-*-*-*

delighted to see this published 🙌 using EMA, we (with @roryoc.bsky.social) investigated suicidal ideation in daily life. we found that it arises from an interaction of within-person increases in loneliness and an individual’s level of personality functioning psycnet.apa.org/fulltext/202...

This paper is 🔥🔥🔥🔥 Very compelling evidence that the extensive covariance of diverse psychopathology is not an artifact of cross-sectional factor analysis. They show extensive "co-morbidity" across generations and within-person, over time. doi.org/10.1037/abn0...

Thrilled to share a new paper in @jamapsychiatry.com on path asymmetry in complex dynamic systems of psychopathology! jamanetwork.com/journals/jam... With amazing collaborators @tfblanken.bsky.social, Han van der Maas, & Denny Borsboom 🥳

New paper in JAMA Psych, from Alex Moussa-Tooks, myself, Leah Gilbertson, and Sarah Kopelovich at @uwspiritlab.bsky.social. Inside, we talk about the important role of clinical psychology in inpatient psychiatric care and the need for more research in this area. jamanetwork.com/journals/jam...

A new take on the limitations of "psychometric networks" now out in Nature Human Behavior. You don't want to put too much confidence in individual edges. Something we cautioned against in 2017. 1/2 www.nature.com/articles/s41...

Out today in Molecular Psychiatry our paper on multiverse computational factor modeling (i.e. a lotta lotta factor analyses). Thread below for the full rundown. Last PhD paper from @celinef.bsky.social YOU'RE FREE!! www.nature.com/articles/s41...

Great study! A general implication is that when we infer effects of retrospectively measure variables on outcomes, we’re largely just seeing the effects of how people are currently feeling.

New LIB is good, finally! denver really brought the heterosexuality and the cringe. PERFECT

I just googled the title of a paper of mine that hasn't even been published yet (as a lazy way to find the preprint) and Gemini popped out an AI summary of it. So I guess preprints on PsyArXiv are being used in AI training sets? 🤔

Thanks everyone for retweeting this! We've gotten all the speakers we need so far. Looking forward to sharing more with yall in a few months :)

New paper in Nature Mental Health where we show that macroeconomic income inequality is associated with brain structure and function over and above individual-level SES and other state-level factors. These alterations may serve as pathways to mental health problems. www.nature.com/articles/s44...

We already know that lagged effects in CLPMs are likely to be upwardly biased, but just how easy is it to find significant effects? Way too easy. I tested CLPMS in 100 randomly selected pairs of correlated variables and found significant effects in 98 of them. New preprint: osf.io/preprints/ps...

This was a fantastic collaboration with lots of people including @hilarycmartin.bsky.social @jakobgrove.bsky.social, Experts by Experience, and several others who I can't seem to find on this app. Article: www.nature.com/articles/s41...

Hi bluesky friends! I plan to submit a symposium with @craiganthonyrs.bsky.social for APS 2026 on contextual psychopathology research from ECRs (students welcome!) Content area and methods are wide open. If you are interested or know someone who may be, message me and we'll chat further. 1/2

My website is official 🙌 Excited to share that I am interested in reviewing applications for Harvard’s Clinical Science PhD program this fall as I look for the first student to join my lab! I appreciate it if you can share with your network :) psychology.fas.harvard.edu/people/mark-...

That’s two reported ChatGPT suicides in one week, plus the grandpa who died trying to meet Meta’s chatbot which had arranged an in-person meeting All going really well

I will be interviewing for a clinical psychology PhD student in the Precision Psychopathology + Dynamic Immunopsychiatry Lab this interview cycle. Please see our website for more info about what we do + share with applicants you think might be a good fit. share.google/uJRyS3NY9Kdo...

The National Institutes of Health has removed gender identity variables from the ongoing Adolescent Brain Cognitive Development (ABCD) Study, @thetransmitter.bsky.social has learned. By @callimcflurry.bsky.social #neuroskyence www.thetransmitter.org/gender/abcd-...

I cannot emphasize this enough: Please do not use AI tools as therapy. Not only is it not a good replacement for actual therapy, but your chat logs could be shared with the government, and I don't think you need a reminder that especially right now in the US, that could put you in danger.

MASSIVE RCT of app-based CBT skill delivery showing all active conditions (isolating behavioral activation, cognitive restructuring, problem solving, + assertion training) beat 3 different control conditions h/t to team led by @toshi-frkw.bsky.social #PsychSciSky www.nature.com/articles/s41...

New Viewpoint in the Journal of Psychopathology and Clinical Science on the use of the term “normal” in the DSM over time. It’s increasing, and it’s an unclear term. I found the discussion of this fascinating. Check it out. psycnet.apa.org/record/2026-...

I was wondering if anyone who got a clinical psych PhD in the US and/or got licensed in the US has experience applying for predoctoral internships in Canada. I would love to hear more about what this process looked like from folks who have experience navigating it.

No. Next question.

Post-bacc RA job posting is now live! Great fit for applicants interested in graduate degrees clinical psychology and/or precision medicine. Please repost + share with potentially interested candidates. So excited to find a new team member to work closely with wd1.myworkdaysite.com/en-US/recrui...

Some personal news: This fall, I’ll be joining Stony Brook’s Clinical Psychology faculty as Assistant Professor! So excited to start my lab, and hope to accept PhD students next cycle. Looking forward to working with prosp. students interested in computational clinical psychology / personalization.

My annual psych internship rant, now with even more 🔥. The pre-PhD internship is an outdated model that devalues the expertise psych students bring. Now, we may be requiring students to move to unsafe cities and unstable positions, during a stage when healthcare and reproductive rights are critical.

Though we're in a new version of the world where lies are truth, i do have to correct the record and say I won 10-1.

Exciting news! We’re thrilled to announce that tapir Yuna gave birth to a rare and endangered Malayan tapir calf Sunday night. The newborn, covered in distinctive white spots and stripes resembling a fuzzy walking watermelon, is only the second tapir born in our 120-year history.

I am an immunopsychiatric researcher and I approve this message. The importance of the immune system as an input/output of so many systems is why it is a critical area of work. But that is also why we need slow, thoughtful science to avoid harm. academic.oup.com/brain/advanc...

💫💫💫 Extremely excited about our new pre-print leveraging the strengths of hierarchical dimensional models of psychopathology to identify distinct behavior profiles from smartphone sensor data! Check out @aidangcw.bsky.social 's awesome thread on our findings!

Wanted to share news of the publication of this research paper with @auerbachlab.bsky.social and others. Using the EARS mobile sensing platform, we found that being homebound more than usual was associated with increased risk for suicidal behaviors in high-risk adolescents.

I am hiring a full time study coordinator for our EBI-BD study which uses EEG, cognitive testing, EMA, and wearables to study emotion-based impulsivity in bipolar disorder. Excellent position for someone who is interested in grad school! careers.umich.edu/job_detail/2...
