Psychopathy as Unified Theory of Crime /
No full textThis book applies the psychopathy concept toward the understanding of crime. Drawing on hundreds of studies and his own clinical, research, and practitioner experience working with the most antisocial and violent offenders, the author demonstrates that psychopathy can explain all forms of crime across the life course, and also examines the biosocial foundations of the disorder. With an abundance of case studies and historical references, written in a distinctive writing style, the book is equally fascinating to the academic scholar and the true crime buff alike
The PCL-R family of psychopathy measures: Dimensionality and predictive utility of the PCL-R, PCL: SV, PCL: YV, SRP-III, and SRP-SF
Get PDFThe PCL–R and its derivatives are the dominant assessment of psychopathy in research and clinical practice, and studies examining the measures’ construct validity, dimensionality, and predictive utility are abundant. However, there are controversies regarding the underlying factor structure of the scales, and many published empirical investigations focused on confirming rather than validating the measures, warranting further scrutiny of the PCL–R family of psychopathy assessment. The current chapter summarizes extant knowledge and critically evaluates research into construct validity, dimensionality, and predictive utility of the PCL–R, PCL: SV, PCL: YV, and SRP–III (including its abbreviated version, the Self-Report Psychopathy Scale–Short Form [SRP–SF])
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Psychopathic Personality Traits Model (PPTM): A new approach to defining psychopathy
Get PDFThe Psychopathic Personality Traits Model (PPTM) offers an alternative psychopathy assessment based on personality traits that consists of four dimensions, including affective responsiveness, cognitive responsiveness, interpersonal manipulation, and egocentricity. It is also conceptualized that intelligence levels moderate that relationship between the aforementioned psychopathic traits and behavioral outcomes. Importantly, while antisocial/criminal tendencies/behaviors may constitute one possible expression of psychopathy, they are not treated as integral to psychopathy construct within the newly developed framework. Using this personality approach to psychopathy assessment, we demonstrated that the prevalence of psychopathy among individuals incarcerated in medium and maximum security prisons amounts to approximately 7 percent of the total prison population and hence is much lower than previously speculated, comparable with the prevalence found among non-forensic adult samples. It is recommended that both researchers and practitioners re-evaluate the previously utilized conceptualization of psychopathy and assessment methods. Additionally, psychopathy measures which index behavioral traits and rely on cut-off points for total scale ratings should be used with caution in clinical settings
