Prevalence of psychopathy in a community sample of Spanish adults: Definitions and measurements matter

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.

Factor Convergence and Predictive Analysis of the Five Factor and Alternative Five Factor Personality Models with the Five-Factor Personality Inventory for ICD-11 (FFICD)

The authors analyze and compare the factor convergence and predictive power of the Revised NEO Personality Inventory (NEO-PI-R) and the Zuckerman-Kuhlman-Aluja Personality Questionnaire (ZKA-PQ/SF) with respect to the Five-Factor Personality Inventory for ICD-11 (FFiCD). A total of 803 White Spanish subjects were analyzed. All the personality domains had significant predictive power with regard to the FFiCD except NEO Openness. The explained variance of the personality domains with respect to FFiCD Negative Affectivity (71% and 77%) and Detachment (56% and 56%) were similar for NEO-PI-R and ZKA-PQ/SF, respectively, but the NEO-PI-R accounted for greater variance for FFiCD Anankastia, Dissociality, and Disinhibition. The FFiCD facets of Rashness, Thrill- Seeking (Disinhibition), and Unassertiveness (Detachment) were located in factors other than those theoretically expected. The authors conclude that normal personality measured by the NEO-PI-R and the ZKA-PQ/SF contribute, in a differential but complementary way, to knowledge of the maladaptive personality measured by the FFiCD.

Temperaments and characters: incompatible or complementary components for criterion B of the alternative model in predicting DSM-5 section II personality disorders?

BACKGROUND

Many studies have found clear correspondence among the domains of the five-factor model of personality (FFM) and the alternative model of personality disorders (AMPD) in DSM-5-III, which is assessed with the Personality Inventory for DSM-5 (PID-5). However, very few studies have compared the PID-5 with the other well-known established dimensional models of personality such as Cloninger's model. The present study examined whether the Temperament and Character Inventory (TCI-125) dimensions, PID-5 dimensions, or a combination would represent PD-scale scores more accurately.

PARTICIPANTS AND PROCEDURE

In this regard, 437 college students completed the Persian version of the PID-5, TCI-125 and SCID-II Screening Questionnaire.RESULTS The results indicated that cooperativeness (low), self-directedness (low), and self-transcendence (high) characters of the TCI-125 and the psychoticism (high) domain of the PID-5 are the most consistent predictors of all PD-scale scores.

CONCLUSIONS

Overall, the findings showed that an integrative model, combining dimensions of the TCI-125 and PID-5, represented the features of PD-scale scores most effectively.
