Due to challenges with the current funding climate I won’t be reviewing clinical psych PhD applications this cycle. Sorry to miss out on the chance to mentor more amazing ECRs but hopefully things improve in the coming years.

Excited this measurement manuscript is out. 6+year effort to address what we saw as limitations in how we use the PHQ-9. Work by @dawsonhaddox.bsky.social in collabo w my partner in (measurement) crime @eikofried.bsky.social. If you use PHQ for weekly assessment or symptom-level analyses, read this!
🚨 New preprint! Across six studies (N=2,467), we evaluated three modular adaptations to the PHQ depression measures: separating double-barreled items, adding irritability and low-libido items, and supporting past-week assessment. 🧵1/7 osf.io/preprints/ps...

Excited to share a new Annual Review paper with @eriknook.bsky.social : "Large Language Models in Mental Health Research and Treatment." Here lay out what LLMs actually are and aren't, then take a census of how mental health research has used them so far, where it's heading 🧵1/n
Really proud of this work that came together as a pet peeve project of a few NSMD PhD candidates, and now ended up in New Ideas in Psychology. What are symptoms? www.sciencedirect.com/science/arti...

The term symptom pervades mental health research, yet its meaning remains ambiguous. In this paper, we argue that the lack of clarity and consensus on…

@lluaces.bsky.social with another banger! Thoughtful research design plus amazing writing equals another paper that will go on my lab’s required reading list.

Those of us who were trained at CTSA by Edna Foa will be very familiar with this. I love Exposure and Response Prevention (ERP)! I've licked the bottom of my shoe many times when working with OCD (and still do it 2x per year when I teach my undergrad and graduate courses on CBT). And much more...
Just grabbed the doorknob and licked the palm of my hand for the benefit of a therapy client. That's what you call dedication!
Eiko is the best! If I didn’t have a family I’d quit my job and move to the Netherlands to work with him. Highly recommend these positions to any who might be interested!
In addition to a hiring PhD in ~October & hopefully some PhDs and postdocs ~February, if anyone would like to work with me as part of eg a Marie-Curie or something similar, please do get in touch. Topics include depression, classification, measurement, systems, time-series, & theory building.
What to do when #AI meets #OpenScience? @stokel.bsky.social spoke to me & other colleagues about this pressing issue for this @nature.com article. @drandreahoward.bsky.social @katiecorker.bsky.social @miriforbes.bsky.social @debruine.bsky.social
My latest for @nature.com looks at the challenge researchers are facing thanks to bots scraping their data uploaded alongside their research - and what they think ought to be done about it www.nature.com/articles/d41...
I had a great time giving my first conference talks, sharing my work on depression assessment and digital phenotyping at #APS26BCN! Grateful to my mentor (@depressionlab.bsky.social), my collaborators (Drs. Fried, Allen, Craske, Sachdeva, and many others), and everyone I met and learned from there.
Fantastic work by @cherilev.bsky.social and her team - truly a joy getting to collaborate with all of them to integrate/adapt their work on treating eating disorders into our digital therapy ecosystem (credit/thanks as always to Michelle Craske ~ UCLA DGC/ADRC). @personalizedtx.bsky.social

We just got approved to hire a teaching professor in Quantitative Methods! This is the *very* rare tenure track teaching position at Berkeley. I'll be chairing the search committee. Official job ad coming later this summer!
NHS data should be driving innovation & improvement – it’s an amazing resource We just published the sequel to our 2021 "Road to Hell" paper on using NHS data for research... things are worse! Buckle up for a long 🧵about *how COMPLETELY mad* system is for accessing NHS data for research 1/20
Selecting an effect size for power analysis is hard. Many researchers fall back on Cohen's thresholds, but they have no empirical basis and vary wildly by field. Our new paper offers a better option: field-specific effect size distributions built from meta-analytic data doi.org/10.3758/s134...

Hey friends, my new paper was just published in JAMA Psychiatry. I draw on biological species classification to sketch a new framework for psychiatric nosology. Brief summary follows below. Full text link: jamanetwork.com/journals/jam... 🧪 #PsychSciSky #MentalHealth
Mental Disorders as Homeostatic Property Clusters
This narrative review explores the idea of understanding mental disorders according to homeostatic property clusters rather than through typical classification systems.

Cuts to scientific research will have effects for years to come. @standupforscience.bsky.social has been an important voice connecting scientists & all of us. @cdelawalla.bsky.social leads that group, & her latest post is a call to action to restore funding 👇🏿👇🏼👇🏾👇🏻👇🏽 substack.com/home/post/p-...
Scientists, it's time to pay your taxes.
This arrangement—where a small number of dedicated scientist activists fight for the whole of the ecosystem—isn’t sustainable.
