Aaron T. Beck is winner of the Lifetime Achievement Award from the National Nursing Centers Consortium! This important work presents a cognitive framework for understanding and treating personality disorders. In one volume, Aaron T. Beck and his distinguished co-authors offer both a comprehensive overview of scientific knowledge and a detailed guide to individualized treatment. Part I lays out the conceptual, empirical, and clinical foundations of effective work with this highly challenging population, and Part II describes the process of cognitive-behavioral therapy for each of the specific disorders. Chapters demonstrate the nuts and bolts of differential diagnosis, case conceptualization, and intervention, with particular attention to therapeutic impasses and how to overcome them.
