In this landmark work on object relations, Dr. Jill Savage Scharff addresses the psychological processes of projective and introjective identification and countertransference. Dr. Scharff brings fresh insight to the neglected concept of introjective identification and a new understanding of the therapeutic action of projective and introjective identification. The book's unique distinction is in the author's integration of object relations theory and practice, particularly with regard to the handling of countertransference. The clinical material is written in the vivid and personally candid style that is a hallmark of her work. Dr. Scharff demonstrates how to understand and utilize projective and introjective identification, making this work indispensable for every dynamically oriented therapist.
