Based on decades of influential research, this book delves into perfectionism: how it develops, its underlying mechanisms and psychological costs, as well as how to effectively target it in psychotherapy. The authors describe how perfectionistic tendencies—rooted in early relational and developmental experiences—make individuals vulnerable to a wide range of clinical problems. They present a comprehensive treatment approach and demonstrate ways to tailor intervention to individual clients' needs. A group therapy model is also analyzed. Contemporary assessment tools are included and provided on the accompanying website. Throughout the book, vivid clinical illustrations make the key ideas and techniques concrete.
