Robert Langs, a psychoanalyst, has been the most vocal advocate of the very tight therapeutic frame. In a Langsian office, there are no decorations that might provide any hint about the therapist as a person. The environment is very neutral. Often not even kleenex is provided as that could be construed as gratifying the patient. It isn't being anal just to be anal but because every little thing is seen in the light of what it means in the therapy. So as many variables as possible are controlled in order to have a better idea of what is coming from the patient and what is aroused by the frame.
According to Langs and his followers, the therapist's office is supposed to be in a neutral medical office type building. A bill is to be sent at the end of the month with a check sent in by the patient for the sessions covered by the bill. No physical contact at all with the patient, including a handshake. If the patient brings a gift, it is not accepted but remains unopened and the offer of it discussed for meaning. If the patient sends the therapist a letter, the envelope remains unopened and is there the next time the patient comes.
In the late 80's, Langs published a number of books illustrating his ideas about analysis. They are essentially transcripts of seminars and supervision sessions he conducted with psychiatric residents. This was how I first encountered his ideas. I worked for three years with a clinical supervisor who was supervised by Langs. He helped me to look in detail at all kinds of things like when the patient gives me the check and how we greet at the door.
All of these things can be useful but the rigidity doesn't work for me. Sometimes it is important for a patient to be able to give to the therapist. Thanks to the work in Langs approach, I know how to look at the gift giving and make sure it comes into the therapy and is understood.
When the patient comes in and says "I was thinking about the time I went to buy a car and the car dealer really cheated me", in the Langsian model, the therapist will hear this as a communication about the therapy, what we call a derivative. And will listen and collect the derivatives and then might say "I can hear that you are feeling cheated somehow in our work together and I wonder if you could tell me more about that." Also useful. But I am not convinced that *every* communication is about the therapy.
So the method is valuable to learn.
A brief word of caution -- Langs is not the easiest writer to read, but if you are interested in the process of therapy, the effort is worth it. He tends to same the same things in many of his books, though, so reading one or two of them will likely give you more than you need.
