Since its development thirty-five years ago, the practice of cognitive therapy has been extended well beyond the treatment of depression. It is now effectively used with substance abuse, marital conflict, sexual dysfunction, panic disorders, post-traumatic stress disorders, paranoid delusional disorders, and a variety of other affective, anxienty, and personality disorders. Each chapter in this volume presents state-of-the-art treatment by one of the field's leading practitioners, demonstrating interventions in rich clinical detail for the therapist interested in why the method works and how to apply it. We also see how other theoretical orientations are integrated into the cognitive framework.
