“…Anestis et al (2011) compared three competing models of the PPI-R and found that both the one-factor (PPI-Psychopathy) and the two-factor model (Self-Centered Impulsivity and Fearless Dominance) yielded good fit for the female sample but barely acceptable fit for the male sample, whereas for the three-factor model, fit was modest for both groups. In contrast, Adams et al (2020) did not find empirical support for their eight-factor PPI-SF model, neither in male, nor in female participants.…”

“…A further inclusion criterion was the participants' age (minimum 18 years), since personality disorders are not diagnosed in underage individuals (e.g., American Psychiatric Association 2013). As an exception, we included two articles (Adams et al K 2020;Gummelt et al 2012) with samples that mainly consisted of adults but also 17-year-old individuals.…”

Structural differences in psychopathy between women and men: a latent modeling perspective

Research on sex differences in psychopathy indicates that men generally exhibit higher psychopathy scores than women. Measurement equivalence is an important prerequisite for the investigation of mean differences, but is often neglected for psychopathy instruments. The current research provides a systematic qualitative review of the pertinent literature on measurement invariance between men and women for several rater-based and self-report-based psychopathy assessments. Based on 28 studies, we found that the factor structure and factor loadings are most likely comparable between sexes for four out of nine instruments. Results on item thresholds, however, are inconsistent, which questions the comparability of mean scores between men and women for these instruments. The majority of studies that reported acceptable measurement equivalence indicated higher psychopathy scores among men compared to women. As the current literature is neither consistent nor exhaustive, further research needs to address structural differences in psychopathy between biological sexes more systematically.

“…Vaughn et al ( 2008 ) administered the PPI-SF to assess psychopathic traits in a sample of adolescents ageing out of the child welfare system, though eleven items that did not sufficiently load on to their factors were deleted. Their sample’s mean PPI-SF total score of 104.6 would correspond to a total score of 130.2 on the full 56-item measure (when rescaled by number of items; i.e., multiplied by 56/45)—which is approximately half a SD greater than the mean total score observed in a community sample of N = 1219 U.S. undergraduate students ( M = 124.04, SD = 14.88; Adams et al, 2020 ).…”

Individuals with experiences of alternative care (AC; i.e., out-of-home care and institutional care) are at high risk for various mental health and relational problems stemming from exposure to serious attachment disruptions, loss, and complex trauma. Yet, despite the interpersonal context of their significant adversities, surprisingly there is scant research explicitly focusing on callousness/unemotionality (e.g., lack of guilt, callous disregard for others) in this population. This paper provides the first conceptual model for, and systematic scoping review of, callousness/unemotionality in children and young people with experiences of AC. In a comprehensive search of nine databases, 22 articles involving samples of participants in AC or with histories of AC, were identified for inclusion. The pattern of findings revealed that callous-unemotional and psychopathic traits are elevated in children and young people with AC experiences, and positively associated with AC. Moreover, results showed associations between these traits and various psychosocial correlates, most consistently with externalizing and internalizing problems and attachment-related problems. Only two intervention studies were located, one of which found benefits of training and supporting foster caregivers for reducing callous-unemotional traits. These findings are discussed with respect to gaps in the literature, future research directions, and trauma-informed practice to assess and treat callousness/unemotionality in children and young people with experiences of AC.
