AI Article Synopsis

  • The study investigates psychopathy prevalence in the general adult population using different theoretical perspectives and the Big Five personality model for comparison.
  • A sample of 682 adults from Spain was assessed with the NEO Personality Inventory-Revised, leading to calculations of clinical and subclinical psychopathy prevalence.
  • Results indicated low prevalence rates, with clinical psychopathy at about 0.55% and subclinical at around 1.65%, challenging the notion of a widespread psychopathy problem in society.

Article Abstract

The main objective of this work is to examine the prevalence of psychopathy in the general adult population from the main currently existing theoretical perspectives of psychopathy, using for this purpose the five-factor or Big Five model as a common language that allows the comparison and integration of the personality traits considered as defining psychopathy by these different perspectives. The NEO Personality Inventory-Revised (NEO PI-R) was applied to a sample of 682 adults of the general Spanish population. The prevalence of clinical and subclinical psychopathy was calculated according to six different definitions of these two constructs based on Hare's, Lilienfeld's, triarchic, and DSM-5-hybrid models, and the simultaneous presence of a minimum number of personality traits that differed from the sample mean by one standard deviation. Prevalence rates for the different definitions were consistently low, indicating that the prevalence of clinical psychopathy in the general Spanish population is around 0.55%, and that of subclinical psychopathy is around 1.65%. There were no significant sex differences in the prevalence of psychopathy. These results question the alarmist claims that warn about the existence in society of a very high number of people with psychopathy who can cause many social, economic, physical, and psychological damage to others.

Psychopathy is a personality disorder characterized by affective-interpersonal features and an impulsive-antisocial lifestyle. Psychopathy commonly co-occurs with other forms of psychopathology, but current understanding of how behavioral features of psychopathy co-occur with, or are distinct from, other mental health problems is limited. In this study, we analysed data from a large sample of young adults to study the relationship between different facets of psychopathic traits and general psychopathology ("p").

Article Synopsis
  • The study investigates the link between childhood emotional neglect and traditional victimization in secondary vocational school students, emphasizing the need for targeted prevention interventions due to the high prevalence of victimization.
  • Findings suggest that childhood emotional neglect indirectly contributes to traditional victimization through mediating factors such as family functioning and psychopathy rather than a direct correlation.
  • Socioeconomic status (SES) does not moderate these relationships, indicating that efforts to reduce victimization should address emotional neglect while also improving family dynamics and addressing psychopathic traits.
