OP, I don't think you were addressing all realms of therapy, just that as it applies to attachment work.

There aren't even many studies on the matter, in comparison to other issues. I found a published paper that I took in to my former T and the pdoc who wrote it admits to there not being many case studies on it and it sure as heck doesn't include any mention of what to do when the client becomes attached to the T.

Again, I'm sure it's worked for some and I'd love to read the source material on it, because maybe it would help my situation.
