Relational psychoanalysis, a relatively new and evolving school of psychoanalytic thought, is considered by its founders to represent a “paradigm shift” in psychoanalysis. The relational approach, initiated by the publication of Jay Greenberg and Stephen Mitchell's book, Object Relations in Psychoanalytic Theory in 1983, has developed into a movement with its own substantially separate literature. This paper reviews both the history and theoretical origins of the relational movement, as well as important theoretical premises and viewpoints now associated with the relational school.
