What happens when we break down DSM diagnoses into their individual symptoms and rebuild our classification system from the ground up? Do we see familiar DSM constructs, HiTOP dimensions, or something else entirely?

New paper out today! ✨ journals.sagepub.com/doi/10.1177/21…

Title and author information for the paper at the link in the tweet

How do your favorite disorders fare in a data-driven reorganization of the DSM-5?

Find out in this new preprint where we followed the patterns in 14,762 individuals’ symptoms with the goal of overcoming limitations in both the DSM and @HiTOP_system

A representation of how symptoms of some exemplar constructs in the DSM-5 map onto the hierarchical structure we found. On the left are examples of disorders with symptoms that mostly hung together in the data-driven structure (i.e., ‘notably homogenous disorders’) and on the right are examples of disorders with symptoms that scattered throughout the data-driven structure (i.e., ‘notably heterogeneous disorders’).

Looking through my backlog of emails I found a Christmas morning surprise that this paper made it to print in a real life issue of Psychological Methods! 🎁

Hope these ideas can help streamline some hierarchies

*So* excited this paper is out in the world!

Published paper: psycnet.apa.org/doi/10.1037/me…
Open access: osf.io/ksxwv

It proposes an extended bass-ackward approach based on three modifications to Goldberg’s method for delineating hierarchies 🧵

A comparison of the two solutions: The traditional bass-ackward approach is shown as the “before” picture with 10 components and 12 correlations; the extended bass-ackward approach is shown as a simplified “after” picture with five components and four correlations.

Also, Tash Turner-Cohen is available for casual RA work next year in the Sydney area (or remotely) if anyone is in the market for a brilliant addition to their team!

Just uploaded a new video that provides a brief introduction and overview of HiTOP! Tash did awesome work on this one too.

Hope it can be useful for some of you - please do share it widely with anyone who you think might be able to use it: youtu.be/196rqdAv4_w

Launched a new @HiTOP_system YouTube channel to host some videos my RA Tash Turner-Cohen and I are working on.

We've just posted the first one, which gives a brief overview of some of the limitations of the DSM: youtu.be/4Kwu_1oMD9U
