Reconstructing Psychopathy: Clarifying the Significance of Antisocial and Socially Deviant Behavior in the Diagnosis of Psychopathic Personality Disorder

Abstract

A survey of clinical views suggests that the significance of antisocial and socially deviant behavior in the diagnosis of psychopathic personality disorder is unclear. To investigate this issue, we evaluated Psychopathy Checklist-Revised ratings (PCL-R; Hare, 1991) using structural equation modeling. One model, referred to as the measurement model, included PCL-R ratings related to antisocial behavior as primary symptoms of psychopathy; a second, referred to as the causal model, included the same PCL-R ratings as secondary symptoms or consequences. Compared to the measurement models, the causal model included more PCL-R items, was more parsimonious, and had equal or superior fit indices. These findings suggest that antisocial behavior is best viewed as a secondary symptom or consequence of psychopathy, In addition, the findings have important implications for future research and clinical-forensic practice, especially concerning the assessment of risk for criminality and violence.
