[Method of plan formulation: first German language rehabilitation study of the Joseph Weiss "control mastery theory"]

The paper gives a survey of the "Control Mastery Theory" (CMT) of Joseph Weiss. CMT is a cognitive-affective, psychoanalytic theory of the psychotherapeutic process. The San Francisco Psychotherapy Research Group empirically investigated und confirmed several concepts of the CMT. Some research results are summarized and the "Plan Formulation Method" is described in detail. The results of the first German reliability study applying the plan formulation method on the case "Amalie" show that the method can be used reliably for research purposes outside the USA.
