Summary

Understanding the causes of psychopathy is limited due to diagnostic debates. Further research into biological factors and consistent definitions is needed for a comprehensive model of psychopathy.

Area of Science:

  • Psychiatry
  • Neuroscience
  • Criminology

Background:

  • Psychopathy diagnosis and concepts are debated.
  • Understanding the etiology of psychopathy remains limited.
  • Advances in psychopathy research are hindered by conceptual issues.

Purpose of the Study:

  • To review the literature on psychopathy.
  • To identify gaps in the understanding of psychopathy's etiology.
  • To highlight the need for further research into biological determinants.

Main Methods:

  • A comprehensive literature search of the PSYCHLIT database was conducted.
  • Publications spanning five decades were reviewed.
  • References from existing reviews were traced to identify additional relevant studies.

Main Results:

  • Over 200 articles were initially identified.
  • 95 selected articles were included in the final review.
  • The review highlighted a lack of consistency in operational definitions.

Conclusions:

  • Brain dysfunction's role in psychopathy requires further investigation.
  • Biological determinants of psychopathy are under-researched.
  • A multi-modal research program is necessary for a comprehensive model of psychopathy.
