TLDR
Using confirmatory factor analysis, the authors tested the 2-factor PCL:SV model of psychopathy and recent 3- and 4-factor models and results indicated good fit for each model, with the 4-Factor model showing best overall fit.Abstract:
One hundred forty-nine inpatients within a maximum security psychiatric facility were assessed with the Psychopathy Checklist: Screening Version (PCL:SV; S. D. Hart, D. N. Cox, & R. D. Hare, 1995). Within the total sample, 68% had a psychotic disorder and 30% met criteria for psychopathy. Using confirmatory factor analysis, the authors tested the 2-factor PCL:SV model of psychopathy and recent 3- and 4-factor models. Results indicated good fit for each model, with the 4-factor model showing best overall fit. Structural equation modeling was used to determine which psychopathy factors predicted 6-month follow-up of inpatient aggression. The 2-, 3-, and 4-factor models, respectively, accounted for 16%.27%. and 3l% of the variance in aggression.read more

Psychopathy as a clinical and empirical construct.
Robert D. Hare,Craig S. Neumann +1 more
TL;DR: In this paper, the authors focus on two major influences on current conceptualizations of psychopathy: one clinical, with its origins largely in the early case studies of Cleckley, and the other empirical, the result of widespread use of the Hare Psychopathy Checklist-Revised (PCL-R) for assessment purposes.

Psychopathic, not psychopath: taxometric evidence for the dimensional structure of psychopathy.
TL;DR: The results across these procedures offer no compelling support for the contention that psychopathy is a taxonic construct and contradict previous reports that Psychopathy is underpinned by a latent taxon.

Psychosis as a risk factor for violence to others: a meta-analysis.
TL;DR: A quantitative review of research on the association between psychosis and violence indicated that psychosis was significantly associated with a 49%-68% increase in the odds of violence, however, there was substantial dispersion among effect sizes.

Capturing the four-factor structure of psychopathy in college students via self-report.
TL;DR: links with self-reports of offensive activities (including entertainment preferences and behavior) supported the construct validity of the oblique four-factor model and exhibited appropriate construct validity in a nomological network of related personality measures.
Journal ArticleDOI
A taxometric analysis of the latent structure of psychopathy: evidence for dimensionality.
TL;DR: Recent advances in taxometric analysis were added to P. Meehl's (1995) multiple consistency tests strategy for assessing taxonicity, and they indicated that both the individual components of psychopathy and their interface are distributed dimensionally.

Cutoff criteria for fit indexes in covariance structure analysis : Conventional criteria versus new alternatives
Li-tze Hu,Peter M. Bentler +1 more
TL;DR: In this article, the adequacy of the conventional cutoff criteria and several new alternatives for various fit indexes used to evaluate model fit in practice were examined, and the results suggest that, for the ML method, a cutoff value close to.95 for TLI, BL89, CFI, RNI, and G...
