This study validates Levenson's Self-Report Psychopathy Scale (LSRP) in a general population. Findings confirm its reliability and two-factor structure, supporting its use in assessing psychopathy outside clinical settings.

Area of Science:

  • Psychology
  • Criminology
  • Forensic Psychology

Background:

  • The Levenson's Self-Report Psychopathy Scale (LSRP) is a key instrument for assessing psychopathy.
  • Its reliability and validity in non-institutionalized populations require thorough examination.

Purpose of the Study:

  • To evaluate the reliability and validity of the LSRP in a non-institutionalized population.
  • To examine the factor structure of the LSRP and its correlation with antisocial behavior and personality traits.

Main Methods:

  • Two studies were conducted: one with 1,958 undergraduates and another with 70 participants.
  • Confirmatory factor analyses and performance tasks were utilized to assess the LSRP's psychometric properties.

Main Results:

  • The LSRP demonstrated strong reliability and validity, with its two-factor structure being consistently replicated.
  • Significant correlations were found between the LSRP and measures of delinquency and personality traits.
  • Undergraduates scoring high on the LSRP exhibited response modulation deficits similar to incarcerated psychopaths.

Conclusions:

  • The LSRP is a reliable and valid measure of psychopathy in non-institutionalized individuals.
  • The findings support the two-factor model of psychopathy and its applicability across different populations.
  • The study highlights the utility of the LSRP in research and potentially in clinical settings for identifying psychopathic traits.
