This book provides a systematic survey of the theories of psychotherapy from an intergrative perspective. Looking within an individual system of therapy, the book follows the integrative steps that flow from the system's theory of personality to its theory of psychopathology and culminates in its theory of the therapeutic process and relationship. The book also offers an integrative framework that highlights the similarities of therapy systems without blurring their essential differences. The authors include case examples demonstrate how the same complicated psychotherapy case (Mrs C.) is formulated and treated by each system of psychotherapy.
