Psychopathic personality disorder (PPD) has important clinical and forensic implications. But much more effort has been devoted to assessing or diagnosing PPD than to explicating or defining it. In the first part of this paper, we describe the development of a conceptual model or "concept map" of PPD. Based on a systematic review of descriptions of PPD in the clinical and research literature, as well as consultation with subject matter experts, we identified key features of the disorder and translated them into 33 symptoms, presented as natural language (i.e., non-technical) trait descriptive adjectives or adjectival phrases. Each symptom in turn was defined by three synonymous adjectives or adjectival phrases. The 33 symptoms were grouped rationally to reflect six domains of personality functioning. In the second part of the paper, we discuss research completed and in progress intended to validate the CAPP conceptual model.

Cooke and colleagues recently developed the lexically based model of psychopathy named the Comprehensive Assessment of Psychopathic Personality (CAPP, Cooke, Hart, Logan, & Michie, 2004). The current study was the first to evaluate aspects of the validity of a translated version of the CAPP model, which comprises 33 symptoms from six domains of personality functioning. Prototypicality ratings from 796 Norwegian community residents, forensic mental health professionals, and corrections professionals were obtained. Most CAPP symptoms were evaluated as highly prototypical of psychopathy by all three groups. Symptoms from the Self, Dominance, and Attachment domains were perceived as more prototypical than those from the Behavioral domain. Confirmatory Factor Analysis (CFA) indicated that two CAPP domains were unidimensional whereas evidence of unidimensionality was somewhat weaker for the other domains, but improved substantially after removal of problematic symptoms. Overall, the findings support the content validity of the CAPP model. This may have relevance to the current considerations regarding reformulation of the criteria for Antisocial Personality Disorder in DSM-V.

The Comprehensive Assessment of Psychopathic Personality (CAPP) is a newly developed, lexically based, conceptual model of psychopathy. The content validity of the Spanish language CAPP model was evaluated using prototypicality analysis. Prototypicality ratings were collected from 187 mental health experts and from samples of 143 health professionals and 282 community residents. Across the samples the majority of CAPP items were rated as highly prototypical of psychopathy. The Self, Dominance, and Attachment domains were evaluated as being more prototypical than the Behavioral and Cognitive domains. These findings are consistent with findings from similar studies in other languages and provide further support for the content validation of the CAPP model across languages and the lexical approach.

Recent exploratory factor analysis (EFA) of the Psychopathic Personality Inventory (PPI; Lilienfeld, 1990) with a community sample suggested that the PPI subscales may be comprised of two higherorder factors . However, little research has examined the PPI structure in offenders. The current study attempted to replicate the Benning et al. two-factor solution using a large (N=1224) incarcerated male sample. Confirmatory factor analysis (CFA) of this model with the full sample resulted in poor model fit. Next, to identify a factor solution that would summarize the offender data, EFA was conducted using a split-half of the total sample, followed by an attempt to replicate the EFA solution via CFA with the other split-half sample. Using the recommendations of Prooijen and van der Kloot (2001) for recovering EFA solutions, model fit results provided some evidence that the EFA solution could be recovered via CFA. However, this model involved extensive cross-loadings of the subscales across three factors, suggesting item overlap across PPI subscales. In sum, the two-factor solution reported by was not a viable model for the current sample of offenders, and additional research is needed to elucidate the latent structure of the PPI.
The concept of psychopathy is unlike most other mental disorders in the lack of observations of vulnerability and pain in those affected. Rather, the psychopath’s callous and self-centered ways are known to evoke suffering in others. Measures are developed to identify these characteristics in a reliable way. However, increased accuracy has not led to better treatment. As a consequence, this study aimed to investigate whether the current understanding of psychopathy is changing, or should be changed, and if central changes in the concept and measurement of psychopathy require a modification of the way we handle the problem today? Hallmarks of the current paradigm were challenged through 3 research questions: 1. Are psychopathy and suffering mutually exclusive constructs? 2. Is the psychopath more than the persistent callous, grandiose and ruthless characteristics that we usually see? 3. Is the psychopath deprived of a capacity to change? The first article of the thesis reviews previously published (1980-2009) cases of offenders with severely psychopathic traits (n=11). Vulnerability and pain in psychopaths were consistent with empirical evidence and concepts associated with object relations theory, Reid (1986) and Martens’ (2002) clinical experience of suffering in psychopaths, and comorbid symptom- and personality pathology, as indicated by the authors’ assessment and the selfreport of individual offenders. Articles two and three draw from an in-depth investigation of Norwegian high-security and detention prisoners with possible and strong indications of psychopathy (n=16) and controls (n=35). Results indicate important nuances in psychopathic offenders’ affective and interpersonal functioning in terms of relational uncertainties and pain, and a greater emotional range than what is previously reported. Results further indicate a link between empirical findings and clinical theory describing structural affective, relational and defensive nuances in pathologically extreme self-states, which should be considered in future treatment of psychopathy. Results are incongruent with Cleckley’s (1941; 1988) recognized description, and the wellestablished primary-secondary psychopathy distinction (Karpman, 1941), and in agreement with the dimensional model of self- and interpersonal functioning advised in APA’s (2010) proposed revision of personality diagnoses. Future work should focus on the vulnerability and suffering, nuances and adjacent treatment of psychopathy. Such an approach would represent a paradigm shift in this field.
Understanding Psychopathy Using the Basic Elements of Personality
Social and Personality Psychology Compass, 2015
Psychopathy is a form of personality disorder characterized by arrogance, self-absorption, callousness, exploitation, and impulsivity that is also strongly associated with antisocial behavior. The present paper argues that psychopathy can and should be understood as a configuration of personality traits from a general model of personality functioningthe five-factor model (FFM). In this paper, we demonstrate that previous theoretical conceptualizations of psychopathy and current empirical ones converge on a general FFM profile characterized by very low scores on agreeableness and conscientiousness and mixed relations to aspects of neuroticism and extraversion. Further, we articulate the advantages to understanding psychopathy in this way. The FFM provides an assay of extant inventories, explains the factor structure of various inventories, accounts for the epidemiology of psychopathy, and makes sense of the litany of putative psychopathic deficits. Perhaps most importantly, the FFM provides a connection to basic research in personality.
