This book develops the techniques of ACT into a session-by-session approach that therapists can use to treat clients suffering from depression. The research-proven programme outlined in the book introduces therapists to the ACT model on theoretical and case-conceptual levels. Then it delves into the specifics of structuring interventions for clients with depression using the ACT method of acceptance and values-based behaviour change. Written by one of the pioneering researchers into the effectiveness of ACT for the treatment of depression, this book is a much needed professional resource for the tens of thousand of therapists who are becoming ever more interested in ACT.
