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… 1/🧵

Ever wondered how many symptoms make up all of adult psychopathology described in the DSM-5? It’s 628! How many do you think repeat across multiple diagnoses? If you answered 231 symptoms repeating a total of 1022 times (median 3 times per symptom, range 2-22), good job! 🧵

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 x.com/PsyArXiv_bot_v…

One disorder in particular stood out: The diagnostic criteria for major depression dominated the lists of symptoms that repeat the most. This is bad news for diagnostic accuracy, with misattribution of symptoms and inflated comorbidity seemingly likely outcomes. 6/

Does anyone have advice on how to manage a 'to read' pile? I download pdfs and put them in a folder, but often let the papers just sit there gathering digital dust. I'd love to hear how others chip away at staying on top of the literature #AcademicTwitter @AcademicChatter

This new preprint has some cool findings and very sexy figures that summarise five years of work on the symptom overlap among DSM-5 diagnostic criteria. psyarxiv.com/u56p2/ 2/

So the good news is that in my current project I'm learning really cool stuff about a symptom-level structure of psychopathology, but the bad news is I'm now pretty sure my whole PhD was wrong

For example, more than a third of the diagnoses have *every* symptom repeating in at least one other diagnosis These plots show the patterns of symptom repetition for each chapter (each in high resolution with symptom and diagnosis labels here: osf.io/6yrmx): 3/

Now in print, open access in Psychological Medicine! 🎉 doi.org/10.1017/S00332… Thanks to you all for your enthusiastic response to the paper - it made it even more fun and rewarding for our team to work on. Now onto modelling these pesky symptoms in real world data!

We have a new look official model for @HiTOP_system! It depicts everything covered in the original Kotov et al. 2017 paper in a single figure, including the components and traits from Figure 3, and the Externalizing superspectrum described in-text.

All in all these patterns increase my motivation to do fine-grained work on the structure of psychopathology, which I believe can move us towards a better set of constructs to study. Preprint link again: psyarxiv.com/u56p2/ 7/7

Just posted a preprint of a v. brief descriptive paper on the implications of the symptom-level overlap among DSM diagnoses for the HiTOP model. Mostly I had fun making this cool Sankey diagram, but I also found a few interesting results! psyarxiv.com/f5gqz/ 🧵
