Screening for light personalities in Portugal: a cross-cultural validation of the light triad scale with an at-risk-of-delinquency sample

Publication . Pechorro, Pedro; Baptista, Makilim N.; Bonfá-Araujo, Bruno; Nunes, Cristina; DeLisi, Matthew

The Light Triad of personality refers to three prosocial personality traits-Faith in Humanity, Humanism, and Kantianism-that promote the worth and dignity of other people, focus on ethical behavior and empathy, and confidence that other people are naturally good. The aim of the present study is to examine the psychometric properties of the Light Triad Scale (LTS)-Portuguese version. Our convenience sample consisted of 242 male and female participants (M = 30.19 years, SD = 12.78, range = 16-77) from Portugal. The proposed latent structure models of the LTS obtained adequate fits. Internal consistency/reliability, as measured by the alpha and omega coefficients, was adequate to good. Construct validity with other psychometric measures (i.e., empathy, dark traits of personality, propensity to morally disengage, and antisociality/criminality measures) and criterion-related validity (with justice involvement variables such as problems with the law, arrested by the police, sentenced to prison and alcohol/drug abuse variables) were demonstrated. Cross-gender measurement invariance was established, with females scoring higher than males. The findings support the use of the LTS as a valid and reliable measure.

Psychometric examination of the proposed specifiers for conduct disorder self-report (PSCD) among an adult community sample from Brazil

Publication . Pechorro, Pedro; Bonfá-Araujo, Bruno; Baptista, Makilim Nunes; Nunes, Cristina; DeLisi, Matt; Salekin, Randall T.

The Proposed Specifiers for Conduct Disorder (PSCD) is a promising novel scale that measures psychopathic traits and includes an additional conduct disorder factor that taps the antisocial dimension of psychopathy. The current study sought to broaden the application of PSCD by examining the factor structure, convergent and discriminant validity, and connections to delinquency in a young adult sample ( N = 450; M = 31.91 years, SD = 13.02 years) obtained from the Brazilian community. Participants completed a self-report version of the PSCD along with other theoretically meaningful psychometric measures. Results supported a four-factor intercorrelated factor structure, with male participants scoring significantly higher than female participants on the PSCD total, grandiose-manipulative (GM), callous-unemotional (CU), daring-impulsive (DI), and conduct disorder (CD) factors. The four factors of the PSCD mainly presented positive, moderate to high significant inter-correlations and adequate reliability. The convergent validity with measures of the dark tetrad of personality, difficulties in emotion regulation, and self-reported delinquency also revealed positive moderate significant associations. Our findings support the use of the PSCD as a promising short, time-effective self-report measure of psychopathic traits in young adults.
