So I’m not a doctor but as I understand it, CAT-Q effectively is a booster for the RAADS-R. A lot of the RAADS-R is either understanding or recognizing the symptoms of autism, but people who are high masking (aka “camouflaged”) have often learned to hide/not notice their autistic traits. Reminder of course, the “A” in CAT-Q means “autistic”.
That said, I think 100+ on RAADS-R before a fairly high CAT-Q is something worth considering alone.
I have a special interest in psychology and if this was something related to a mental health condition I would be the first to tell you that the best way to learn is peer-reviewed studies, published references like the DSM-5 (imperfect as it may be) and so on. However, autism is not a psychological issue, it’s a neurological difference. This means that the best way to learn is to talk to autistic people (which you currently are!) and see if the little things that make you/them “weird” resonate with each other. If you’re feeling more introverted than that, you could maybe find an autistic YouTuber that “clicks” with you and see how their experience compares to yours.
