The Great Psychotherapy Debate is one, if not the most, important book ever published about psychotherapy. Whether at the beginning, middle, or end of one's career, it is a must read. -Scott D. Miller, PhD, director of the International Center for Clinical Excellence The first edition of The Great Psychotherapy Debate served as a gauge tossed at the feet of the prevailing medical model of psychotherapy. Professor Wampold cogently brought together the literature in the area and provided a compelling option to the empirically supported movement. As a result there has been a wealth of research examining important issues pertaining to treatment effects. The second edition is a marked improvement over the first in its inclusion and thoughtful summary of the research in the area, providing an accessible summary of what we know and what needs to be examined. The scope is broad, covering both theoretical subtleties as well as sophisticated empirical analyses. It is written to serve both the skilled psychotherapy researcher as well as advanced students in the field. An extremely important book! -Terence J. G. Tracey, PhD, ABPP, professor and faculty head of the counseling and counseling psychology program at Arizona State University. The first edition of this book was a seminal publication that helped to organize vitally important information regarding the effects of psychotherapy. The second edition updates this work with the most contemporary research and also extends the discussion on the effects of psychotherapy along several different pathways, offering important implications for the future of the field. I believe this book should be required reading for graduate students as well as anyone conducting psychotherapy research or implementing institutional policies for the delivery of psychotherapy. -Mark Hilsenroth, PhD, professor at Adelphi University.
