Freud and Klein describe projective processes—projection, projective identification, and the repetition compulsion—that cause interpersonal distortions not only in the psychotherapy relationship but in adult intimate relationships as well. Winnicott's theory of the use of an object describes a way of relating that is free of the distortions of projection, opening up the possibility of differentiation between intimate partners. Two case examples illustrate how addressing projective processes assisted one patient in extricating herself from a psychologically abusive relationship and helped a couple in treatment to move from object relating to object use. It is argued that the use of these psychoanalytic theories has an important role within a modern relational social work practice.
