The Factor Structure and Construct Validity of the Short Version of the Youth Psychopathic Traits Inventory in Two Independent Samples of Nonreferred Adolescents.

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.

Adaptive and maladaptive personality traits in high-risk gamblers.

Gambling Disorder (GD) is an addictive disorder resulting in significant impairment in occupational and social functioning. The aim of the present study was to investigate the relationship of GD risk to adaptive and maladaptive personality dimensions in a sample of nonreferred Italian gamblers. The authors found the risk for GD to show significant associations with the Openness and Conscientiousness scales of the Big Five Inventory (BFI); however, these effects were not significant after controlling for alcohol and drug use.
