The third edition of Behavioral Interventions in Cognitive Behavior Therapy reflects a comprehensive, inclusive, and thoughtful approach to scaffolding essential competencies for learners of cognitive behavior therapies. Farmer and Chapman illustrate the behavioral science framework, teach functional analyses, and facilitate a conceptual understanding of common components of cognitive behavior therapies for flexible, individually tailored application in an approachable and highly readable manner. These foundations, the broad range of assessment and intervention techniques, and related sociocultural and ethical considerations are invaluable for those already practicing evidence-based cognitive behavior therapies as well as learners of modular, process-based therapy. - Claudia Drossel, PhD, PhD, Associate Professor, Department of Psychology, Eastern Michigan University, Ypsilanti, MI, United States This third edition of Farmer and Chapman amp rsquo s exceptional text is up-to-date and filled with overviews of theory, research, and many guidelines for competent application of the behavioral strategies in cognitive behavior therapy.

It is an excellent reminder for those who have been in the field for some time, and an informative and enjoyable amp quot nerd amp quot read for the seasoned expert. - Christopher Martell, PhD, ABPP, Professor of Practice and Clinic Director, Psychological Services Center, Department of Psychological and Brain Sciences, University of Massachusetts Amherst, Amherst, MA, United States
