A Call for Greater Transparency in Piloting doi.org/10.1177/2515...

New paper! Despite qualitative researchers claiming that generalizability is not a goal, their published work does indeed contain generalizable claims. We document this and provide recommendations for how all researchers can better calibrate their generalizability claims. doi.org/10.1177/2515...

After 12,000+ user interactions, we're releasing the first major update of Synthometricon (formerly SynthNet, with @anniria.bsky.social and @ruben.the100.ci ) 🧵 Try it here search.synth-science.org

How do we know if clinical interventions for suicidality “work”? A scoping review of suicide trial outcomes doi.org/10.1037/cps0...

"250,000 respondents can produce an estimate of the population mean that is no more accurate than an estimate from a simple random sample of size 10" reminds of recent Nature journal paper with N=billions but lacking the studied variable so the study is actually nonsensical doi.org/10.1525/coll...

Identifying distinct trajectories of change in anhedonia during psychological treatment for depression doi.org/10.1017/S003...

Since our paper on the Changing How I Live Life (CHILL) Study is now out in Psychological Science (doi.org/10.1177/0956...), here's a LONG overdue post on the intervention work we've been doing the past few years! Have you ever wanted to change one of your personality traits?

New paper! We find that the Reliable Change Index (RCI), used to statistically evaluate whether an individual patient improved, is operationalized so inconsistently across clinical trials in psychology that results are often incomparable... (1/n)

🚨 Paper Alert 🚨 Our new study on the impact of a single small zombie trial on fluoxetine's overall efficacy estimation is out. With great colleagues @floriannaudet.bsky.social @richlyus.bsky.social and Gert van Valkenhoef 🧟‍♂️🧟‍♀️🧟 A longer 🧵 (1/n)

Very cool new paper by @aleksakaurin.bsky.social, Mario Wenzel, @paulaphilippi.bsky.social using some of my K99 data: osf.io/preprints/ps... EMA studies often ask people how they feel several times a day. But when is a change bigger than measurement noise? And does the person actually feel change?

NEW: researchers say one 'zombie' study in Iran, 20 years ago, has skewed the world's medical evidence base for using Prozac to treat depression in children. They stop short of saying don't use Prozac this way, but want clinical guidelines revised. @nature.com www.nature.com/articles/d41...

If you read one paper on the conceptualization of mental health problems this year, make it this one. Much of it aligns closely with my views—bummer it's not published elsewhere. Curious what you think and which clinical, research, or logical weak spots you see. doi.org/10.3389/fpsy...

Gave a talk in my dept. on the OSF transition. I wrote up a rough script of the session, which could be of interest to others. I synthesize existing resources and provide my own perspectives. Comments and corrections welcome! zenodo.org/records/2306...

Our review introducing HiTOP to German-speaking readers will soon appear in Psychologische Rundschau, reviewed and approved by the Research & Publications Board of the HiTOP Society. English translation now on OSF: doi.org/10.31234/osf... @hitop-system.bsky.social

📝 Excited to share an accepted first-authored paper at Clinical Psych Science! Why are so many mental disorders treated as unidimensional? We show support for 1-factor models is often just an artifact of conventional psychometric methods -- which weren't designed with psychopathology in mind.

Barriers and facilitators to implementing patient-reported outcome and experience measures (PROMs/PREMs) in health systems: a comprehensive overview of systematic reviews www.sciencedirect.com/science/arti...

New preprint with @violetsarebrown.bsky.social: "Measuring Up: Accessible Approaches for Improving Measurement Practices in Psychological Science." The aim of the paper is to reduce barriers to entry to doing measurement work in Psychology. #schmeasurement osf.io/preprints/ps...

Hayes has been banging this drum about idionomic analyses for 6+ years, with folk like @jamiecummins.bsky.social pointing out that its reinventing-the-wheel-but-worse for just as long. My experience is that the ACT community is insufficiently interested and aware of existing methods+stats work.

Our commentary "A Revolution in Search of an Estimand: On the Idionomic Proposal of Hayes et al. (2026)" is now available as a preprint: osf.io/preprints/ps... With @rpsychologist.com, @matti.vuorre.com, and Nils Hentati Isacsson.

"Systematic reviews are only as credible as the studies they include" INSPECT-SR was published yesterday, giving concrete guidance on how to exclude untrustworthy studies. Cochrane's statement: www.cochrane.org/about-us/new... Article: www.cochrane.org/about-us/new... Guidance: inspect-sr.com

This is an *excellent* post on cluster analysis. If you ever thought about applying cluster, latent class or latent profile analysis to psychological scales, you absolutely should read this!>

New blog post: "Cluster analysis: A skeptic’s guide". In which I ask a few questions that social scientists wishing to identify hidden classes in their data ought to address. janhove.github.io/posts/2026-0...

Impairment in the hierarchical taxonomy of psychopathology doi.org/10.1037/pas0...

New preprint: population-representative norms for the PID-5 and its short forms (PID-5-SF, PID-5-BF, PID5BF+M), conditional on age and gender, for the German population. With @andrekerber.bsky.social, Christoph Kemper & Katharina Weweck. osf.io/preprints/ps...

Pretty excited to have just published our latest video, a clinical case example using HiTOP. This was a team effort with the Clinical Translation Workgroup, but very much led by the brilliant @tashtc.bsky.social ✨ We hope it might be useful, and are keen to hear any feedback! youtu.be/Hl6bA4roCNU

Okay before I do write my screed about cluster analysis, please send me your favorite *positive* examples that illustrate the utility of the method!

"Remember that each patient a psychiatrist treats is effectively a single-subject prospective, open-label observational trial where the control group is the memory of every other similar patient who the psychiatrist has seen."

あさイチのシンポジウムもとても勉強になった。偏愛的といえるぐらい決定的な問いを立てられるか，ヒトを対象にした質の高いデータを取得できるかというのは，たしかに今後さらに大事になるだろうな。 このガイドもとても参考になる。 kairi-pf.com/documents/ps...

A dialectic on validity: Explanation-focused and the many ways of being human dergipark.org.tr/en/pub/ijate...

I know that authors usually don’t pick headlines, but even then, this one is a bit bold for a piece that literally says “There are currently no scientifically valid biomarkers for any psychiatric condition, with the exception of certain proteins used to diagnose Alzheimer’s disease.”
