As managed care systems become the most important health care providers in the United States, they are revolutionzing the way that clinicians supply psychotherapy. Financial considerations and the size of client pools have led to the increasing substitution of group sessions of individual psychotherapy. In this new environment, clinicians must be thoroughly conversant in group therapy techniques to be effective providers. Written by an authority on group therapy, this work provides new and experienced clinicians with generic models for the development of efficient and effective interactive groups able to deliver a wide variety of treatment options. It offers a comprehensive examination of the potential of group psychotherapy and an appreciation of time management in its utilization. Based on empirical research and illustrated with numerous examples, this text discusses a variety of treatment models that employ various combinations of supportive, cognitive-behavioral, interpersonal and psychodynamic techniques.
