Welcome to #TransTuesday!

National Coming Out Day is Oct 11, so let’s get into what can be a difficult and complicated issue for so many of us: COMING OUT AS TRANS.

And for the first time since Trans Tuesdays started, I reprint my own coming out thread!

Oops. It bounced back. I must have an old email for you. DM me your email and I resend.

Just sent you the PDF.

Excited that this one is live and doubly excited that I've already been able to replicate the majority of the findings in NESARC wave 1 (GAD & MDD) and wave 2 (PTSD).

If anyone knows of any publicly available data sets with *DSM-5* PTSD, please let me know!!

I require this for my folks. Code and data.

Oof. Stats Gestapo.

Let's see a mimeograph of those hand calculations!

And if there is anyone reading this and feeling like they don't have to requisite skill to share their code and show their work, I'd be more than happy to help.

But as Kevin said, SPSS can output syntax. The "SPSS is bad" convo is separate from the "show your work" convo, and the latter is critical. Folks are so quick to take offense to "soft science" accusations, but this one reason why our science is soft AF. It's time to level up.

I mean, I still don't understand. Clearly I'm either too old or not "online" enough. But if it's intentional antagonization, that's some fucking bullshit. Of all the crap we have to deal with in this stupid epoch of ours, the explosion of intentional antagonization of vulnerable people is the worst.

There is no excuse. Is this science? Or is it kindergarten arts and crafts? Seriously. You can't show your work?? GTFO.

Someone please explain to me why people are angry that the CEO of Blue Sky is posting about waffles.

Great googly moogly!! I just submitted a review where I recommended reject. Went and checked what the other reviewers thought and R1 recommended 'accept with minor revisions'. I am just so confused right now.

Where does one submit a methodological comment? Like, not a new method, just a "hey, have we thought about this?" kind of thing?

Going to the gym is not antithetical to going to the library. Fitness is a key element of longevity and sound mental health.

Aaron Fisher @aaronjfisher.bsky.social · 8d

A bit nitpicky, but wouldn't the 0/1 variant be the more common model in our field?

I do. This is a major focus of my research at the moment. I will send you some stuff in a couple of hours (currently out and about). Thank you!!

Aaron Fisher @aaronjfisher.bsky.social · 9d

Perhaps. Again, I'm not super talented with coding. I would need different routines to build them out and then populate them. If you have any suggestions, that would be great!

Aaron Fisher @aaronjfisher.bsky.social · 9d

I'm *sure* that there are more efficient ways to do what I'm doing. I am but a humble hack coder in all the worst meanings of the word hack.

In this case every combination is unique. These are the 131,071 possible combinations of DSM-IV PTSD symptoms. FWIW, a later step is to reduce these to a much smaller set of minimally sufficient sets as a function of clinical benchmarks (distress, impairment).

Aaron Fisher @aaronjfisher.bsky.social · 9d

I bought a forever license when I got hired at Berkeley in 2013, but I've never used the program! Do you really think this stuff would move faster in Stata?

It takes a list of set strings and populates them as dichotomous vars into a data frame. The set elements correspond to existing vars in the data frame and as it populates the new vars, it checks the presence/absence of the set elements. If all are present, the new variable gets a 1, else 0.
