“This second edition is perfectly timed, given the explosion of developments in the underlying theoretical principles and empirical research associated with this approach to treatment. The book is beautifully written and is an outstanding resource for clinicians and researchers alike, whether novice or experienced. The principles of functional contextualism and relational frame theory are laid out in an easily understandable yet in-depth manner. The book's presentation of the core principles of ACT—including practical guidance for implementing them in clinical practice—is simply superb. This is an excellent text for graduate students in clinical psychology.”
