Personality constellations in incarcerated psychopathic men
Personality Disorders: Theory, Research, and Treatment
Advances in the operationalization of psychopathy have led to an increased understanding of the boundaries, structure, and nomological network of this construct, although significant questions remain. The empirical identification of replicable and theoretically meaningful psychopathy subtypes may help to improve the classification and diagnosis of this condition. We conducted a classification study of 91 incarcerated men who met conventional criteria for high levels of psychopathy using the
... pathy using the Psychopathy Checklist-Revised. We expanded on the methodology of previous research on psychopathy subtypes by utilizing a comprehensive personality assessment instrument and a prototype matching approach to classification. The analyses revealed a primary (narcissistic) subtype and a secondary (hostile and dysregulated) subtype that were broadly consistent with the previous literature. External validation analyses, statistical controls, and incremental validity analyses provided substantial support for the primary and secondary subtypes. Psychopathy is a malignant personality disorder (PD) with serious, sometimes grave, psychosocial outcomes (Hare, 1970 (Hare, , 1996 . In his classic monograph on psychopathic individuals, Cleckley (1941/1988) described seemingly intelligent and nonpsychotic persons who were non-neurotic and superficially charming, but insincere, unreliable, unloving, and egocentric.
