A resource for anyone who seeks to understand or treat depression, this volume synthesizes the most current research and theory on cognitive vulnerability. Following an overview of recent developments in cognitive psychology, the authors take up several major cognitive paradigms that have particular applicability to psychopathology. Cognitive theories of depression are then presented and literature on the epidemiology, genetics, morbidity, correlates, and treatment of the disorder is reviewed. Subsequent chapters provide an in-depth look at cutting-edge vulnerability models of psychopathology, identifying the core features of such models and probing the interrelationship of risk, vulnerability, and resilience. Empirical and methodological issues relating to the study of both proximal and distal vulnerability to depression are then addressed in depth. Laying a foundation for future research into how to decrease the risk of relapse, shorten the span of depression, and reduce the social and familial costs of the disorder, this volume is important reading for researchers in clinical psychology and psychopathology and will enhance the knowledge base of a wide range of other mental health professionals as well. It serves as a valuable text for advanced courses in clinical psychology, cognitive therapy, and psychology research methods.
