In this profound work, Vittorio Guidano expands upon his earlier seminal contributions on the application of cognitive and developmental principles to individuals struggling with various forms of psychopathology. Here, he fully develops the idea that individuals' experience, both positive and negative, are powerfully influenced by their personal "psychological organizations." Focusing primarily on the eating disorders, the phobias (with agoraphobia as the prototype) obsessive-compulsive patterns, and depression, Guidano illustrates how early developmental experiences and ongoing psychological processes may collude to perpetuate dysfunctional patterns and personal distress. This timely and provocative volume offers exciting new ideas about how to conceptualize and facilitate change in the "self system." With the rare combination of his Renaissance intellect and integrative practical expertise, Guidano has been able to draw together many disparate themes from object relations theory, ego psychology, attachment theory, constructivist models of human cognition, and lifespan developmental psychology. It is must reading for the practicing professional, the helping apprentice, and anyone interested in glimpsing the cutting edge at the growing interface between cognitive and clinical science.
