The principal mechanisms of psychological stress, and their operation in field and clinical settings, are described in this book. It also offers direction for managing stress-related aspects of physical and psychological disturbances. Clinical problems discussed include physical disturbances such as rheumatoid arthritis and renal failure, and psychological disturbances as severe as depression and schizophrenia. The book discusses results of data gathering and analysis on the effects of crowding and disasters, and beneficial effects of social support, as well as challenging some traditional assumptions concerning stress-disorder relationships, based on empirically supported accounts from experimental personality and social psychology. This book should be useful for psychology and psychiatry students, clinical psychologists, psychiatrists, social workers and nurses.
