AbstractThe dark core of personality is a recent construct that encompasses the malevolent, antagonistic, and aversive side of human nature that represents the common inner core of dark personality traits. The aim of the present study is to develop a short, multidimensional, and invariant version of the dark core of personality D70 measure. Two samples of participants were used in the current study (N = 570, M = 35.42 years, SD = 11.41, range = 18–69; N = 242, M = 30.19 years, SD = 12.78, range = 16–77). The new D25 measure was developed, consisting of five factors – Callousness, Deceitfulness, Vindictiveness, Narcissistic Entitlement, and Sadism. All the structural models examined obtained adequate fits (1-factor, 5-factor, 5-factor bifactor, 5-factor 2nd order), but the 5-factor 2nd order model was considered the best option. Internal consistency/reliability, as measured by the alpha and omega coefficients and more traditional indicators, was mainly good. Construct validity (e.g., with moral disengagement, low self-control, and empathy measures) and criterion-related validity (e.g., with justice-involvement variables) were demonstrated. Scalar measurement invariance across gender and age was established, with male participants and younger participants scoring significantly higher than female participants and older participants. The findings provide support for the use of the D25 as a valid and reliable short multidimensional measure of the dark core of personality construct. [ABSTRACT FROM AUTHOR]

We examine the psychometric properties of the Weinberger Adjustment Inventory (WAI) from a modern psychometric perspective, including second-order models, better estimation of reliability, and measurement invariance, among a sample of young adults (N = 610, M = 21.33 years, SD = 3.09 years) from Portugal. Results indicated that only the four-factor intercorrelated confirmatory models of the WAI Distress and Restraint scales, and the two-factor intercorrelated confirmatory models of the WAI Defensiveness scales showed adequate fits. The WAI showed good reliability and distinctive correlates with other psychometric measures and criterion variables. Cross-gender measurement invariance was established. Our findings support the WAI as a valid and reliable measure. [ABSTRACT FROM AUTHOR]

The dark core of personality is a recently developed construct that encompasses the malevolent, antagonistic, and aversive side of human nature. The aim of the present study is to examine the psychometric properties of the dark core of personality D measure, namely D70, and its two shorter versions, D35 and D16, in Portugal. Two samples of Portuguese participants were used in the current study (N = 570, M = 35.42 years, SD = 11.41, range = 18–69; N = 242, M = 30.19 years, SD = 12.78, range = 16–77). The one-factor models of the D70, D35, and D16 obtained adequate fits, but the bifactor and second-order models of the D70 were less than satisfactory. Internal consistency/reliability, as measured by the alpha and omega coefficients and more traditional indicators, was very good. Convergent validity, and criterion-related validity (with trouble with the law, arrested by police, sentenced to prison, and alcohol/drug abuse variables) were demonstrated. Cross-gender and cross-age measurement invariance was established, with males and younger participants scoring significantly higher. The findings provide some support for the use of the D as a valid and reliable measure of the dark core of the personality construct. [ABSTRACT FROM AUTHOR]

The BANC is an individually administered battery designed to assess a wide range of neurocognitive functions (memory, language, attention, executive functions, motor functions, and laterality) in children aged 5 to 15 years old. This study aimed to obtain regression-based norms for 16- and 17-years old. The standardization sample of the BANC was used (Simões et al., 2016), and it comprises 1104 children and adolescents stratified by age (5 – 15 years, n ≈ 100 per age group), gender, school grade, residential and geographic zones. Regression analyses found a significant predictive effect of age and they allowed the calculation of algorithms for estimating normative data for adolescents aged 16 and 17 years. The regression-based norms revealed adequate accuracy and their application makes it possible to extend the assessment of neurocognitive functioning until the end of adolescence.
