- In order to evaluate the nomological network of associations between psychopathy and its sub-dimensions, and Big Five domains and dispositional aggression in adolescence, and its consistency across gender-based sub-groups, 1253 Italian high school students (F = 429, M 824) were administered the Italian translations of the Youth Psychopathic Traits Inventory (YPI), Big Five Inventory (BFI) and the Reactive-Proactive Aggression Questionnaire. Males scored on average significantly higher than females on all measures of psychopathy and aggression, whereas females scored significantly higher than males on the BFI O, C, A and N scales. Bivariate correlations between psychopathy scores, and aggression and BFI domains measures were highly similar in females and males. The majority of regression coefficients based on hierarchical regression models were consistently replicated across gender-based groups; effect size estimates for regression models were large, supporting the hypothesis that psychopathy can be described in terms of general personality traits in adolescence and that the relationships between psychopathy, its sub-dimensions and Big Five personality dimensions, and aggression generally are very similar across gender.

- To assess the internal consistency, factor structure, and construct validity of the Italian translation of the Youth Psychopathic Traits Inventory-Short Version (YPI-S), both the YPI-S and its full version, the YPI, as well as self-reports of delinquency, aggression, and Big Five domains, were administered to two independent samples (N = 868 and N = 881) of Italian community, nonreferred adolescents. The internal consistency of the YPI-S was adequate, and confirmatory factor analyses showed a good fit of the theoretical three-factor model of the YPI-S in both samples. Hierarchical regression models suggested the same pattern of associations with self-report measures of delinquency and aggression for the YPI-S and YPI, although the YPI was a better predictor of Big Five domains than the YPI-S. The findings support the internal consistency, factor validity, and construct validity of the YPI-S.

- The aim of the present study was to investigate if interaction effects among Youth Psychopathic Traits Inventory (YPI) Grandiose-Manipulative (GM), Callous-Unemotional (CU), and Impulsive-Irresponsible (II) may add significant information in predicting self-reports of juvenile delinquent behavior among adolescents. A sample of 558 Italian high school students were administered the YPI and the Self-Reports of Delinquency Scale (SRDS) in order to evaluate interaction effects among YPI GM, CU, and II dimensions. Results showed a significant effect for a three-way interaction among the three YPI dimensions in predicting the SRDS total score, beta = .19, p < .01. In conclusion, the findings seem to underline that a three-factor model of psychopathy may help clinicians and researchers in predicting self-reported delinquency better than the individual factors.

- In the present study, teacher’s ratings, mother’s ratings, and father’s ratings on the Child Problematic Trait Inventory (CPTI) were obtained on two independent samples (N = 381 and N = 406, respectively) of Italian school age children (age range: 6–12 years). Cronbach alpha values greater than 0.80 were observed for all CPTI scale scores based on teacher’s ratings, mother’s ratings, and father’s ratings respectively. Although intraclass correlation values suggested poor parent-teacher agreement, robust weighted least square Confirmatory Factor Analyses (WLSMV CFAs) suggested that the three-factor model of the CPTI was consistently replicated as the best fitting model across all informants. Logistic regression analysis conducted in one of the samples showed that teacher’s ratings and mother’s ratings of the CPTI, but not CPTI father’s ratings, significantly predicted child’s problem behavior at school. Multiple regression analyses showed that CPTI scores were significantly predicted by selected temperament dimensions, but with different relationships for different sources of information. Overall, our findings suggest that the CPTI is a reliable and valid measure of problematic traits with a three-factor structure, although this study indicates that multiple sources of information may prove necessary when assessing psychopathy in school-age children with the CPTI.
