Termination
The act of ending or concluding. In psychotherapy, termination refers to the mutual agreement between patient and therapist to bring therapy to an end. The idea of termination often occurs to both, but usually it is the therapist who introduces the subject into the session as a possibility to be considered. In psychoanalytic treatment, the patient's reactions are worked through to completion before the treatment ends. The early termination that is characteristic of focal psychotherapy and other forms of brief psychotherapy often requires more extensive work with the feelings of loss and separation.
