notme9, how it seems to work in my area is that if the T wants to talk about you with anybody, he tells you who, asks permission, and gets you to sign a release form. You can always choose to not sign it. My daughter's therapist is the same way. When you first start therapy, you sign an informed consent form which spells a lot of this stuff out. You can look back at this and see what you agreed to. If you don't like it, you can ask that it be modified and then sign the revised one (if your T agrees). Now that my T has also become my coach, I had to sign a different form that doesn't guarantee my confidentiality. It says that he can talk to others about me without my signing a release form. He says this new contract supercedes the original therapy contract. So I have given up my confidentiality rights (these are different from anonymity, which is what you get when your T talks to others about you but doesn't use your name). I don't like the fact that we no longer have confidentiality and have told my T this a number of times. But that's what I have agreed to. When he is done being my coach, we are tearing up the contract and going back to the therapy one, which provides confidentiality.

Read your informed consent form to know what your own situation is.
