Jeremy D. Safran, whose work has systematically broadened the scope of cognitive therapy by integrating principles from other therapeutic traditions, probes critical clinical and theoretical issues in this volume of seminal papers. He begins by outlining the implications of interpersonal theory for cognitive therapy, and proceeds to examine emotion and attachment theory, revolutionizing thinking about the role of emotion in the process of change. Chapters on ruptures in the therapeutic alliance provide a sophisticated approach to working with difficult patients. The concluding section on psychotherapy integration highlights the importance of dialogue among diverse therapeutic traditions as a way for clinicians to see and advance beyond their own preconceptions.
