Chapter 7 discusses the transtheoretical approach to psychotherapy integration, and how this approach attempts to meet the goals of preserving the valuable insights of major systems of psychotherapy, to provide practical answers to questions faced by clinicians, to bring some order to the diversity of psychotherapy as a whole, to offer a researchable alternative to a single system, and to offer a set of principles that include the crucial dimensions of psychotherapy. It then discusses the processes of change, its stages, the pros and cons of said change, and the levels of change.
