My thought to those tests is that if there's not an answer that particularly jumps out at you, it's likely to be the "no" or "neither one nor the other" answer. I think you can try to overthink it.
No way. Our criticism of the test questions is valid. Here's my answer to such a question. I didn't see this exact one on a test, but it's about the same as many of them:
"Do you do well at social functions?" Who is there? When did I last see them? What was our interaction like then? Do I know what to answer (based on my current circumstances) when asked what I'm doing with my life by every random acquaintance? How loud is it? What kind of music is playing? Is it too bright? Is it too dark (or worse, having colored lights)? Have I eaten recently and what did I eat? What side of the bed did I wake up on this morning? (Did I even sleep last night?) How many mood swings did I have since then? Is there a specific other activity that I'd rather be doing now? I really could go on and on.
For example, IIRC there is a question on the theatre vs museum in there. I recall lots of people discussing: "well some days maybe, also depending on my mood, and what the show is". If that's how you feel, then you don't have a preference.
They could just have "it depends" as a choice. Let them interpret it as a "no" for all we care. Don't make taking a test into torturous confusion. I just read online from someone who spent seven hours filling out a 45-minute questionnaire. If you're right, the least that they can do is to tell us what you said: "Answer 'no' if you're unsure."
A couple of days ago, I tried again to take a few of those tests. I managed, with difficulty, to do the AQ-10, the ASQ and the CAT-Q. When it came to the RAADS-R, I tried ten questions, then gave up in frustration.
I don't know if this is true, but I read that when they were developing the Ritvo, it was only autistics who made notes in the margins saying "it depends". This just tells you how wrong it is for NDs.
Then there are the questions asking me what other people think of me and my behavior. How should I know? It's not like they're telling me. My family seems to accept me as I am and, despite me asking them to, will not tell me when I'm being inappropriate.
The Ritvo is also specifically designed to uncover masking. I'm not aware of much of the masking that I've done and do. I definitely cannot answer those questions about what I was like as a child.
All of this assumes that we are supposed to be taking them alone. We do it because websites suggest that we should. The paper introducing the Ritvo states the test is only meant to be administered in view of, and with the participation of, the diagnosing clinician. They are supposed to use how the patient reacts to the questions as part of their determination.
@MNAus, this is an attack on the tests, not on you.
