This paper reviews experimental psychology goal research and its implications for the therapist doing contract therapy. Clinical examples of various levels of contracts give illustrations, and a technique, the therapeutic double bind, as a form of contract, is detailed. A case study is presented to illustrate the use of the theory. Three situations are suggested in which the authors make use of the double bind: (1) when the client is defeating himself by not following instructions; (2) when the client is playing "Poor Me" or other internal or external games; and (3) when the client has been unsuccessful in his contracts.
