This compilation is divided into three sections. The first, Conceptual Contributions, focuses on the construct of psychopathy, how it differs from the DSM-IV diagnosis of antisocial personality disorder, and its different manifestations in children and adults. The Hare checklist, a key assessment tool for the psychopathy construct, is reviewed in detail. Also included in this section are chapters on information processing deficiencies and the emotional experience of psychopaths. The second section of the book, Clinical Issues and Applications, focuses on assessment of psychopathy, primarily using the Hare checklist, and clinical aspects of the assessment process. Risk assessment and detection of malingering and deception are some of the particular areas that arise with this population. The final section addresses a number of special applications of psychopathy assessment, including the areas of manipulation at work, substance abuse, sexual aggression, criminal lifestyle, and hostage negotiations.
