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. This volume would be of interest to clinical psychologists, psychiatrists, clinicians working in correctional facilities, health care settings, private practice and community-based programs as well as researchers and students.
