Regardless, the authors say you should avoid any therapist who refuses to discuss the rules, clarify them, or listen to your input when setting them up. You need to be completely comfortable while working out your treatment. This could be greatly compromised if you sense that your comments are leaving the office. It goes without saying that your therapist should not discuss your case, or even your status as a client, with anyone else. That's also why you shouldn't choose a therapist who is somebody that you know socially.
Privacy is also important.
Make sure the physical setting of your therapist's office is such that you feel your confidentiality is not being violated. Going to a therapist who shares a waiting room with the local newspaper might not be a good idea. No Sexual Advances should be made by your therapist. Not hard to figure this one out. If this happens in any way at all, you need to stop seeing this person and report him or her to your state licensing board.
