Psychopathy in a noninstitutional sample: differences in primary and secondary subtypes.

Area of Science:

• Psychology
• Clinical Psychology
• Forensic Psychology

Background:

• Early theories propose psychopathy is a heterogeneous construct, appearing in various populations.
• Research has yet to fully explore psychopathy subtypes in non-institutionalized samples, particularly concerning gender differences.

Purpose of the Study:

• To investigate the existence and characteristics of psychopathy subtypes in a large student sample.
• To examine gender differences in these psychopathy subtypes.
• To explore the correlates of identified subtypes.

Main Methods:

• A model-based cluster analysis was performed on data from the Psychopathic Personality Inventory-Short Form (PPI-SF).
• The study included a large sample of 1229 undergraduate students (males and females).
• Subtypes were analyzed based on personality traits, anxiety levels, and external correlates.

Main Results:

• Two distinct psychopathy subtypes were identified in both male and female students.
• Male subtypes differed in specific psychopathic traits (e.g., Social Potency, Fearlessness) and anxiety (Stress Immunity).
• Female subtypes showed variations in overall PPI-SF scores and anxiety levels, with primary subtypes scoring higher and secondary lower.

Conclusions:

• Psychopathy subtypes exist in student populations, supporting its heterogeneous nature.
• Gender influences the manifestation of psychopathy subtypes.
• Findings have implications for theory, research, and clinical understanding of psychopathy in diverse populations.
