In this book, Windy Dryden brings together the four major strands that have shaped his idiosyncratic approach to clinical practice – (i) Cognitive Behaviour Therapy; (ii) flexibility in practice; (iii) Rational Emotive Behaviour Therapy; and (iv) pluralism – an approach he calls ‘Flexibility-Based Cognitive Behaviour Therapy’. Perhaps uniquely for the literature, this volume provides an extended account of how a world-leading therapist personally thinks about and practices psychotherapy. As well as insights from over 40 years as a therapist, the book reflects the most the recent developments in Dryden’s work, and highlights both the different theories he is using and the core building blocks of his practice.Aimed at therapists in training and practice, Flexibility-Based Cognitive Behaviour Therapy presents a rare opportunity to gain an insight from one of the leading figures in the field of psychotherapy.
