Do you think that reusing the DSM symptoms might have influenced the outcomes? It would be interesting to see how robust is the structure by testing it using ICD symptoms, for instance.

It's interesting that whenever things work too well, we become suspicious. And now this association has been reinforced vicariously. Somehow, it feels better when things go wrong in a small and predictable manner.

They're not even mentioning feelings integer. Seems like a big oversight! /s

I think that out of range values can sometimes occur, and it isn't problematic by itself. It is possible to restrain the imputed values to values that do occur in the dataset, but this doesn't necessarily lead to a better model.

I can't think of a specific paper now, but there were big changes to autism spectrum disorder and intellectual disability in the DSM-5. That could be a starting point.

The one similar thing that I found surprising is the fact that ODD symptoms do not count as symptoms if they only occur towards siblings. In other words, the DSM-5 says that it's normal to be vindictive, irritable, or defiant with your siblings. Free pass!

I'm glad the idea is gaining some traction! Regarding the issue of the under-identified model, a paper that suggested a potential solution. I haven't tried it yet, but it could help make it easier to apply. I wonder how it compares to a MIMIC-style approach, though.

Interesting! In the metal realm, Igorrr and Carnival in Coal should definitely be included as well.

I would agree. I think that the mirt package in R can generate factor scores as sum scores (EAPsum score), and I would assume that other IRT software/packages do that as well.
