ABSTRACT
This chapter provides a brief, but, by no means comprehensive, history of the psychotherapy integration movement while primarily focusing on contemporary integrated psychotherapy approaches from the 1990s to the 2000s. It highlights the establishment of the formal movement of integration in the 1980s. The mid-1990s paved a way for psychotherapy integration among psychiatrists as evidenced by A. Albeniz and J. Holmes's article in the British Journal of Psychiatry that promoted the idea that different perspectives need to work together, while at the same time, keeping their distinct features. The chapter emphasizes that an integrative or unified framework recognizes that patients need a variety of approaches for different problems. Eagle integrated various schools of psychoanalytic thought into an integrated psychoanalytic framework of the mind. He asserts that it is ego psychology that provides a robust framework for a unified theory of psychoanalysis and for the synthesis of related research in other disciplines.
