This is the fourth volume in the widely hailed series of Ericksonian Monographs sponsored by the Milton H. Erickson Foundation as part of its expanding educational forum for mental health professionals. The Ericksonian Monographs make available original work - theory, clinical technique, case material, and research - on the cutting edge of Ericksonian thought and practice. Ericksonian Monographs No. 4 presents a richly stimulating collection of articles which deal with three extremely important areas of development in Ericksonian work: research, integration within the practice of other therapies and medical applications.
