Acceptance and Commitment Therapy (ACT) is an evidence-based contemporary psychological approach to behaviour change that promotes the idea of people living more in line with their values whilst providing them with practical strategies for managing adversity. In this book, Dawn Johnson and Richard Bennett have collated fifty of the questions that have most frequently been put to them whilst delivering ACT training and supervision to a wide range of therapists and other helping professionals.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.
