rolling through DSMV and calling it a day is wild, from my experience, at least with more off the cuff mental disorders a survey containing about a thousand or so questions is the bare minimum. Plus a few more rounds of that as you try to narrow down any other potential disorders it could be, because it turns out this is a really hard field to deal with.

There is definitely utility in getting a diagnosis like this, but i'd imagine most wouldn't for most things other than basic stuff like ADHD, depression, anxiety etc... There is a considerable risk of just being wrong about something, even if you roll through something like ICD10 which is markedly better than the DSMV. If you're lucky there are a few good localized options like the akhtar profiles for SzPD which can summarize the general disorder into a handful of specifics actions more so than a broad behavioral checklist.
