Nice write up of @carrisacocuzza.bsky.social's latest work using brain dynamics to study transdiagnostic symptom profiles. @holmeslab-bhi.bsky.social, @rutgersbhi.bsky.social, and @rutgersu.bsky.social. Likely of interest to @hitop-system.bsky.social oriented folks.

Turns out empirically derived phenotypes (data-driven symptom sets) nested within traditional mental disorders can help reduce diagnostic heterogeneity! We learned so much cool and interesting stuff in this study. I could talk (/post) about it all day, but here’s a few highlights (🧵)

A new paper from the HiTOP Revisions Workgroup (and yours truly) on the conceptual and philosophical underpinnings of the framework. Recommended reading for anyone interested in questions of classification and psychopathology! Here’s the journal article: muse.jhu.edu/pub/1/articl...

Excited to share this new paper in JoPaCS! We tested whether HiTOP dimensions generalize across sociodemographic strata with MNLFA. After correcting for measurement noninvariance, @hitop-system.bsky.social dimensions remained broadly generalizable. Link to paper: doi.org/10.1037/abn0...

I’ve spent the last 8 years(!) working from the position that HiTOP relies too much on analyses of traditional diagnoses, baking in limitations of the DSM, and that we need to move to symptom-level analyses to fix it It turns out that rebuilding HiTOP from the ground up doesn’t change much 💀 1/

A figure of the results from our study, showing a model that looks remarkably similar to the official HiTOP model. There are also important differences like a pathological introversion domain and a combined hypomania/disinhibition dimension.
