"One of the most important treatment developments in recent years has been the theoretical and empirical elaboration of mindfulness and acceptance into evidence-based, cognitive-behavioral protocols. This book by Steven C. Hayes, Victoria M. Follette, Marsha M. Linehan -- three of the most creative thinkers in this area -- have produced a volume surveying the current status of these new intervention strategies across the wide spectrum of psychopathology." - David H. Barlow, PhD, Center for Anxiety and Related Disorders and Department of Psychology, Boston University
