Today I came across the RAADS-R, a diagnostic tool for assessing people who may not display more obvious signs of autisms. Although it had some questions that were difficult to parse, I really appreciated the fact that it makes a distinction between childhood and adulthood feelings or behaviors. So many times I've taken autism quizzes and had the response, "Well, I was exactly like that when I was a kid..."
It's really good to have a diagnostic tool that acknowledges that autistic people change and develop over time. Lack of awareness of that fact is destructive and helps contribute to a lot of chicanery in autistm "treatment."
