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...

Computationally formalising a verbal theory is an eye-opening experience because it forces you to openly state all the assumptions that the theory rest on

Most #EMA / #ESM studies rely on snapshots 📸 But experience is continuous! What if real insights live *between* measurements? 📉 Dr. Leonie Cloos used #m-Path’s continuous line item to collect affective intensity profiles in everyday life: blog.m-path.io/blog/blog-1/...

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

🚨 New paper out in Current Directions in Psychological Science, with @matnoc.bsky.social! We review recent advances in digital & computational methods for understanding, predicting, and preventing suicide.

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-...

Why do participants stop responding in #ESM / #EMA studies? 📱🔔 Average compliance is about 7️⃣9️⃣%, but that hides massive variation. Our new m-Path blog reviews predictors of response compliance: study design, incentives, participant traits, and time effects. 🔗 blog.m-path.io/blog/blog-1/...

Looking forward to expanding our small team a bit as the lab prepares for its 2nd year. We will be hiring 2-3 more volunteer, in-person RAs for our team to start in the fall. Details and application info are at our website. share.google/O1hvtUpPLIlp...

We at the @personalizedtx.bsky.social already knew how lucky we are to have the best postdoc (@juliayarrington.bsky.social), but lovely to see her recognized with @uarizona.bsky.social's Outstanding Postdoctoral Research award AND the Postdoc-as-Mentor award! postdoc.arizona.edu/news/congrat...

Great perspective piece on open-ended questions in ESM data by @bringmannlaura.bsky.social and colleagues that came out of this year's #MITNB meeting!

For instance: @claireecusack.bsky.social just submitted a paper today in which we show that discrete emotion states predict discrete avoidance behavior in SAD with *very* high accuracy. We know this, right? But now we can locate the phenomenon in *specific moments of time* à la JITAI concepts.

New preprint! We investigate the risk of algorithmic bias (across race/ethnicity, gender, and their intersection) in machine learning models predicting suicide attempts across 3 clinical settings in over 1.2 million patients. osf.io/preprints/ps...

⚠️ 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.

Have you been interested in any of the set theory stuff I've been doing recently? Wondered at all how you can get in on the fun? Here's an R package @nicolasleenaerts.bsky.social and I built called 'setweaver.' This vignette should get you up and running. Yay :) cran.r-project.org/web/packages...

Thrilled to announce the Oxford Psychological Networks Summer School (OxPNS)! This is the first-ever psychological network analysis workshop in the UK, to be held in magical Oxford from June 22-26, 2026. To apply and for more information, please visit: oxfordpns.com A brief thread 🧵

We're doing summerpsych.com again this year! PhD curious undergrads, come hang out at the CSI lab, help us push forward a project and develop your social science chops Applications are due March 1st:

I kept reading EMA studies claiming to test etiological theories of AUD, but I realized they never actually measured how people experience AUD in their daily lives. So we set out to see what we could learn with existing data. 1/19 journals.sagepub.com/doi/10.1177/...

If our theories have to do with people's daily experience then we really need to know how well we're measuring daily experience. So we need more of what Kevin's team is doing here! Just because your item has the right words in it doesn't mean you know what it measures, or how well.

We're hiring! The Computational Clinical Science Lab @ Yale is seeking a full-time lab manager/research coordinator to start in early summer 2026. For more information about the position and to apply: forms.gle/LtQwVgPUfaGk... Please share widely & consider applying!

Cool study in JAMA Psychiatry confirms what many have suspected for a while: PHQ (depression questionnaire) instructions are widely misinterpreted by patients. It is unfortunate that a questionnaire as shitty as PHQ-9 has become so ingrained & ubiquitous jamanetwork.com/journals/jam...

Our university press team asked me a few questions in regards to the new chair on Mental Health & Data Science. I sketch a bit of a vision on the importance of transdisciplinary work, and some obstacles to overcome. www.universiteitleiden.nl/en/news/2025...

What a week! After 5 days, the #mitnb workshop has come to an end. We had a keynote on time scales and two workshops on careless responding and reliability. The central part of the workshops were the hackathons. We had super diverse hackathons, all designed to assess measurement in #ESM. (1/4)
