A bit like an extension of the notice of Celine, that I share: CBT are often presented as a series of technical protocols, while any psychotherapist recognizes that in practice it happens "not always" like this; at least I hope! The authors focus on the key processes of ACT (and well beyond the ACT ...) and also give relevant suggestions about processes to target first, with this individual in front of us, given its specific context. By the way, this part of the book also shows a pragmatic alternative and more relevant for clinical practice, a diagnosis according to DSM. Finally, I appreciate the balance between the great ambitions of the ACT (and reading this book we begin to suspect that such ambitions are perhaps not unfounded) and characteristic modesty psychotherapists integrity. A book that can also inspire other schools than those of CBT therapists, among others to have a new understanding why their approach works, as well as suggestions to adjust their approach to them while remaining consistent, so without feeling obliged to become "eclectic" when sometimes it works less well.
