You asked. I answer.
Please stop the overuse of “assigned male/female at birth.” It’s rude.
You started out wanting to avoid writing male/female as assumed, which is good, but you stopped and got comfortable too soon.
When it comes to noting the sex or gender in case conceptualizations, I recommend going to why you’re listing it at all.
please consider “socialized as male/female” instead of “assigned male/female at birth” unless you’re actually talking about the experience at birth.
If you’re talking about dysphoria with the gender marker on the birth certificate, please say gender marker.
If you’re talking about genitalia, please consider saying “experiences dysphoria with genitalia/penis/vagina.”
If it is about being read as female while identifying as nonbinary, say that exactly as such.
If the client asks their gender to be referred to and by what was assigned at birth, do this.
If this person is a female who was assigned male at birth, you could just write female and note this person’s transition exactly in ways that is relevant to your case. If she says she is a “transwoman” rather than “woman,” you can likely use that word too by following her lead.
This could be tricky. One, there is a practice of listing everything in case conceptualizations as though “just because.” Two, listing everything could help the supervisors or peers notice what the practitioner has missed.
I do note here though that someone being white isn’t what matters here. If I read a case conceptualization listing someone as white male in mid 20’s, I would still ask if this person had reported experience of racism or racialization. It not about the fact but the experience of it. There are few occasions where one should ever say “assigned male/female at birth” and be as justified as you think.
Now, this is just me as a person. But I am writing this because I want to answer all the questions you “always wanted to ask a trans person.” What they don’t tell you is that they ask these questions then completely ignore the answers because they don’t fit their opinion. It is up to you to use what I provided you to set yourself apart.
Actually, only a couple of people asked. The rest just assumed they already knew. Do you know how jolting it is to hear you say “a friend of mine who was assigned female at birth”!? Why can’t you ask this person what gender they are and refer to them properly.
