There are five separate sections to this book, and they are arranged in a logical sequence. Section One covers normal phenomenology of human behavior, including issues of learning and growth and development. Section Two addresses the theories of human development (which has implications for problem behavior) as well as the psychosocial issues in health care delivery. The latter are those issues that clearly are not psychopathology, but which represent problems in health care delivery that physicians encounter in the no~mal practice of medicine. Section Three is an overview of psychopathology in both children and adults, and Section Four deals with the diagnosis and treatment issues involved in various forms of psychopathology and problems of living. Section Five is the overview of the different systems of health care delivery and the incidence/prevalence of different health care problems. This is a review text and should not be substituted for more complete texts. The authors do not recommend that this book be used as a course text except in those academic offerings that are specifically directed to an overview of the behavioral sciences and psychiatry. To use this book effectively, the beginning student should begin with the first section and progress through the text in a systematic fashion. For the more advanced student, e. g. a psychiatric resident, the basic information in Sections One and Two might be skipped, and the resident could proceed directly to Sections Three and Four.
