Psychopathy remains one of the least understood personality disorders and one of the most intransigent to therapeutic amelioration. Better understanding of this disorder is not helped by its DSM definition, which specifies diagnostic criteria in terms of concrete antisocial behaviors rather than psychological dynamics. In a concerted effort to remedy this situation, Psychopathy brings together a distinguished array of contributors to provide an up-to-date review of this perplexing disorder, including its causation and manifestations. Etiological explanations range from genetic to cross-cultural influences. Encompassing all the significant viewpoints regarding the nature of psychopathic personalities, the volume surveys current typologies and treatment approaches. Psychopathy, the first personality disorder to be recognized in psychiatry, remains one of the most perplexing and difficult-to-treat forms of mental illness. It is also a disorder with considerable social consequences, frequently leading to antisocial, criminal, and violent behavior. This authoritative volume brings together leading mental health experts to provide an up-to-date overview of psychopathy--its nature, causes, and effects on the individual and society, as well as current treatment approaches. Ideal for psychologists in clinical and forensic settings, the volume is also a rich resource for legal professionals, students, and policymakers. Salient topics covered include links between psychopathy, criminality, and violence; assessing the risks of criminal recidivism; how psychopathy may relate to such problems as substance abuse, sadistic behavior, and pedophilia; whether prevention and rehabilitation are possible; and the management of dangerous psychopaths in the criminal justice system.
