Area of Science:

  • Psychiatry and Criminology
  • Psychological Assessment

Context:

  • Traces the conceptual evolution of 'psychopath' from historical perspectives to the modern US-American definition.
  • Highlights the operationalization of psychopathy through Robert D. Hare's Psychopathy Checklist-Revised (PCL-R) with 20 diagnostic criteria.

Purpose:

  • To present the contemporary understanding of psychopathy as defined by US-American researchers.
  • To contrast the modern concept with older German definitions, emphasizing its focus on antisocial behavior and relapse.
  • To demonstrate the validity and empirical support for the PCL-R diagnosis.

Summary:

  • The modern diagnosis of psychopathy, particularly via the PCL-R, targets a specific cohort of offenders characterized by a lack of conscience and a propensity for recidivism.
  • Empirical evidence across various investigative levels validates the PCL-R as a reliable diagnostic tool for psychopathy.
  • The study illustrates the interconnectedness of personality traits and behavioral patterns in individuals diagnosed with psychopathy, utilizing J. v. Uexküll's functional circle concept.

Impact:

  • Provides a clear, empirically supported definition of psychopathy for clinical and research settings.
  • Enhances understanding of the personality-behavioral nexus in psychopathic individuals, aiding in targeted interventions.
  • Contributes to the refinement of diagnostic practices and the study of recidivism in forensic psychology.
