Psychopathic, not psychopath: taxometric evidence for the dimensional structure of psychopathy.
TLDR
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.
Comparing the relative fit of categorical and dimensional latent variable models using consistency tests.
TLDR
An approach to consistency testing is presented that builds on prior work demonstrating that parallel analyses of categorical and dimensional comparison data provide an accurate index of the relative fit of competing structural models.
The two-factor model of psychopathic personality: evidence from the psychopathic personality inventory.
TLDR
A meta-analysis of studies that have examined theoretically important correlates of the two PPI factors and CH suggests that FD and SCI are orthogonal or weakly correlated, each factor predicts distinct (and sometimes opposite) correlates, and the FD factor is not highly correlated with most other measures of psychopathy.
A taxometric analysis of psychopathic personality.
TLDR
Examination of the latent structure of psychopathy in a sample of 309 jail and prison inmates suggested that psychopathic personality may be best understood as existing on a continuum.
The effects of neuroimaging and brain injury on insanity defenses.
TLDR
Defendants diagnosed with a psychotic disorder, defendants who could demonstrate the existence of a brain lesion via MRI, and defendants who had a history of brain injury were more likely to be found not guilty by reason of insanity than those defendants who did not present any neurological testimony.
Youth with psychopathy features are not a discrete class: a taxometric analysis.
TLDR
Although youth clearly vary in the degree to which they manifest psychopathy-like personality traits, there is no natural, discrete class of young 'psychopaths.
The psychology of spite and the measurement of spitefulness.
TLDR
A self-report Spitefulness Scale is introduced to assess individual differences in spitefulness and be able to predict behavior in both laboratory settings and everyday life, contribute to the diagnosis of personality disorders and oppositional defiant disorder, and encourage further study of this neglected, often destructive, trait.
Does attention-deficit/hyperactivity disorder have a dimensional latent structure? A taxometric analysis.
TLDR
A set of taxometric analyses using data from the NICHD Study of Early Child Care and Youth Development revealed a dimensional latent structure across a variety of different analyses and sets of indicators for inattention, hyperactivity/impulsivity, and ADHD.
