The chapters in parts 4, 5, and 6 are stand-alone articles. They do not all follow the same format, yet they manage to cover similar territory, and the text has a coherent feel to it. Despite its length, the book is not encyclopedic, in scope or in style, as the authors provide opinions and analyses as well as descriptive material; in this respect, reading it is much like attending a graduate seminar with the top scholars in each area. It is good to see the sometimes-marginalized marital therapies, constructivist and narrative therapies, group therapy, and other types of therapy treated in the main section of the text. While the individual chapters in parts 5 and 6 are excellent, they encompass a more eclectic, less coherent collection of topics.Handbook of Psychological Change is not a how-to manual, although readers will find ample references to resources for learning the various approaches. Rather it is an ambitious and demanding, but humble, work on the science of psychotherapy that places the person squarely within the frame of discussion.
