The Revised Assessment of Sadistic Personality (ASP-8): Evidence for Validity across Four Countries

Subclinical sadism, characterized by infliction of cruelty, aggression, or humiliation on another for subjugation or pleasure, provides important information in the prediction of aversive behaviors that have implications for individuals' and society's well-being worldwide. Given sadism's universal relevance, it is imperative that researchers ensure valid and reliable trait measurement not only among English-speaking individuals, but also cross-nationally among countries in which sadism remains relatively understudied. The objective of the current research was to validate the revised version of the Assessment of Sadistic Personality (ASP-8) (Plouffe et al., 2017) across samples of Russian (n = 1087, M_age = 37.36, SD = 10.36), Greek (n = 1195, M_age = 35.64, SD_age = 13.08), Serbian (n = 443, M_age = 28.10, SD_age = 6.60), and British (n = 511, M_age = 28.50, SD_age = 11.62) adults. Overall, results supported the reliability, dimensionality, and scalar/partial scalar measurement invariance of the ASP-8 across cross-national samples. Convergent and discriminant validity were mostly supported through correlations with general personality traits, the Dark Triad, emotional intelligence, mental toughness, depression, anxiety, stress, satisfaction with life, aggression, and attitudes toward social groups. Based on our findings, we recommend the use of the ASP-8 in future investigations of aversive traits.

Dark Traits, Harassment and Rape Myths Acceptances Among University Students

The convergence of Machiavellianism, narcissism, psychopathy and sadism is known as the "Dark Tetrad." Our understanding of the relationship between the Dark Tetrad, harassment and Rape Myths is limited. While men are more likely to blame victims of sexual violence, it is unclear how gender influences the ability to perceive harassment. The aim of the present study is to look at the relationship between dark traits, gender, Rape Myths and perception of harassment. A sample of N = 210 university students located in England & Wales were recruited on SONA and social media platforms. Student's t-tests, Pearson's correlations, and multiple linear regressions were conducted. Analyses revealed gender differences for both Rape Myths endorsement and perception of harassment. Furthermore, a relationship between the dark traits, Rape Myths and perception of harassment was founded. These results have several implications, including our ability to understand perpetrators' characteristics, the impact of the Dark Tetrad on Rape Myths and perception of harassment, and our ability to develop effective prevention programs.

The Dark Side of Humanity Scale: A reconstruction of the Dark Tetrad constructs

There has been an absence of consideration regarding measurement invariance across males and females in the widely available Dark Tetrad (DT) scales which measure psychopathy, Machiavellianism, narcissism and everyday sadism. This has resulted in criticisms of the measures, suggesting that the assessed constructs are not wholly relatable between the groups. This article documents the construction and validation of the Dark Side of Humanity Scale (DSHS), which measures dark personalities from an alternative viewpoint, determined by the constructs as they emerged from the male and female data, whilst aligning with theory and attaining invariance between sex. Across four samples (n = 2409), using a diverse range of statistical methods, including exploratory graph analysis, item response theory and confirmatory factor analysis, a divergence from the widely available DT measures emerged, whereby primary psychopathy and Machiavellianism were unified. This corroborated past research which had discussed the two constructs as being parallel. It further supported the DSHS with a shift away from the traditional DT conceptualisation. The resulting scale encompasses four factors which are sex invariant across samples and time. The first factor represents the successful psychopath, factor two addresses the grandiose form of entitlement, factor three taps into everyday sadism whilst the fourth factor pertains to narcissistic entitlement rage. Construct and external validity of the DSHS across two samples (n = 1338), as well as test-retest reliability (n = 413), was achieved. The DSHS provides an alternative approach to investigating the dark side of human nature, whilst also being sex invariant, thus making it highly suitable for use with mixed sex samples.
