"Bergin and Garfield's Handbook of Psychotherapy and Behavior Change has been my lodestar throughout my professional career. I always turned to it when I wanted to know the latest thinking in the field: what therapies were being explored, what process variable, what methodologies? I was consistently impressed by the Handbook's inclusion of newer therapeutic approaches as they were developed, newly conceptualized processes of change and methods to explore them. And, always, attention to important issues of diversity. The 50th year anniversary edition continues the remarkable trajectory begun by Bergin and Garfield and maintained by successors."
-Irene Elkin, PhD, Professor Emerita, The University of Chicago; Past President of the Society for Psychotherapy Research

"This epic treatise, after fifty years, reflects the original authors' modeling of thorough research, penetrating interpretations, and ideas for improving the efficacy of therapeutic interventions. Hopefully, forth-coming generations of students, faculty and clientele will thus benefit from the decades of earnest labor invested in their behalf."
