Thanks for the response and the offer, I may do that. It's ironic that I've not logged in since I registered, and your post was only two days ago. My personal situation is exactly the same as when I posted.

I corrected my classification to AvDP so as not to misclassify myself as suffering from Antisocial Personality Disorder. I also denied that I have a lack of empathy.

As luck would have it, the book that my wife assigned me to read eventually discusses empathy, and the Baron-Cohen empathy quotient. The author of the book, who self-identifies as having Asperger's Syndrome, reported a quotient of 19 out of 80, which is quite low. I took the online test myself and answered the questions carefully, trying hard not to judge myself either too harshly or too easily. As a result, I had many answers where I "slightly" agreed or disagreed, and only a few where I strongly agreed or disagreed.

My score was 18.

It's not obvious to me what the real significance of that low score is, but it is enough to make me do some additional study.
