Look no further for an *excellent* overview of HiTOP! This chapter for the upcoming Oxford Handbook of Dimensional Models in Psychopathology does a fantastic job of pulling everything together. Tam Pham is an absolute superstar and I feel very lucky to work with her ✨ osf.io/preprints/ps...

We’ve just launched the HiTOP Teaching Hub—a space to collect and share materials for teaching dimensional models. If you have anything you're willing to share, please contact @kathleenwreardon.bsky.social or @miriforbes.bsky.social Here's what we have so far: www.hitop-system.org/hitop-teachi...

If you’re open to acting as a local host for the 2026 HiTOP Conference, please get in touch with @miriforbes.bsky.social. We’re looking for inexpensive options (e.g., university spaces, rather than hotels) so very open to ideas or suggestions if you’ve had experience organising this kind of event!

Just remember. @hitop-system.bsky.social is a greasroots consortium cum society with vastly fewer resources than APA throws at DSM (and presumably similar for IDC). Most of the work's been done FOR FREE (in kind).

*New preprint* on ND and co-occurring mental health problems from my lab, led by Chiara Caserini! Using longitudinal data from ABCD we asked: What drives poor mental health outcomes in children with high ND traits? Here's brief summary 🧠🌳🏡 www.medrxiv.org/content/10.1.... 1/n

A preliminary brief version of the HiTOP self-report measure (“B-HiTOP”) is now available on our website: www.hitop-system.org/measurement-... 1/2

This handy resource by @caroballing.bsky.social helps translate between the dimensions of the five factor model (Big Five) of personality, the DSM alternative model of personality disorders, the ICD-11 classification of personality disorders, the HiTOP spectra, and the RDoC negative valence domain 📌

Welcome to the Bluesky account for Stand Up for Science 2025! Keep an eye on this space for updates, event information, and ways to get involved. We can't wait to see everyone #standupforscience2025 on March 7th, both in DC and locations nationwide! #scienceforall #sciencenotsilence

@kgjonas.bsky.social is such a boss!!! 😍

Some of our members have submitted a letter to Meta protesting their revised policy on hateful conduct that now allows allegations of mental illness on the basis of sexual orientation and gender identity You can read the letter and list of signatories here: www.hitop-system.org/letter-to-meta 1/2

Also, if you're at HiTOP or SPA, check out my student Anthony's flash talk on the newest project he's working on examining the longitudinal co-variation of alcohol use problems and disinhibited externalizing in a sample of gay and bisexual men.

A very colorful preliminary program for the HiTOP 2025 Conference is now available: www.hitop-system.org/hitop-2025-c...

We have been working on the development of the Japanese version of HiTOP-SR since last year. It's only just begun, but we're looking forward to being able to announce the results!

We evaluated the German translation: doi.org/10.31234/osf...
