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.
