For the book, try Abe Books, which has scholarly books used and is cheaper. Wallin is interesting; I am interested in the mindfulness and metallization ideas, which the workshop is also going to go into.

As far as the therapist revealing an attachment style, this conference is all about the therapist's attachment style, not the client's. It is called "We are the Tools of Our Trade," so attachment style is part of how a therapist works, especially closely with others. And we will cover how there may be layers or modes of occupying each of the different attachment styles depending on the client and situation. The idea behind some of this is that clashes often do boil down to differences in attachment. Or rather that differences in attachment (or too close similarities) can get in the way and we need to be aware of this potential.

I personally don't see a problem with disclosing a general sense of attachment style in the therapist client relationship. It seems to be important information. I will be able to figure it out anyway. It will be in the room just like other things about the therapist. So I'm not exactly sure why a therapist should not say something about it.

My therapist told me his but I had already figured it out. We are both secure from an avoidant insecure background. We have very different personal styles and different life trajectories, histories, etc, but we do overlap in this area. It told me that he can understand that if I do fall back on avoidant and pull away or seem to be functioning without asking for anything that he is careful to not miss that because he understands at a gut level how people are who have an avoidant background. He probably understands the other styles too, but this one he knows because he lived it. Since I know that, I know that I don't even bother to try to retreat back to being avoidant. In other words, and I'm not really putting it that well, but it has helped in understanding and also in action.
