"This book is the first of its kind to provide concise answers to a range of philosophical, theoretical, conceptual, and practical questions raised by practitioners who are learning ACT. It will be of interest to psychotherapists, clinical psychologists, counsellors, psychiatrists, and a broad range of other mental health practitioners and trainees. It serves as a useful resource for those new to the practice of ACT, and for more experienced practitioners who might want to consider these questions themselves"--
