Abstract

Prior studies with children and adolescents have shown that Youth Psychopathic Traits Inventory-Short Version (YPI-S) scores are internally consistent and manifest expected relations with external variables of interest. In the present study, the factor structure and the internal consistency of YPI-S scores, and the convergent validity of the interpretation of YPI-S scores were tested in a sample of 2,500 emerging adults from the general population in Sweden (aged 20-24 years; 52.6% women). Results of exploratory and confirmatory factor analyses support a 3-factor structure among both men and women that is similar to prior YPI-S studies conducted with children and adolescents. The YPI-S total score and the 3 factor scores were internally consistent. Correlations with external variables, including aggression and delinquency, support the convergent validity of the interpretation of YPI-S scores. Finally, the strength of these zero-order and partial correlations, overall, was not significantly different across gender. In conclusion, this study provides initial evidence that the YPI-S may hold promise as a brief and time-effective self-report tool for assessing psychopathic traits in emerging adults. The present findings also suggest that the YPI-S performs in a consistent manner across gender. Recommendations for future research with the YPI-S are discussed. (PsycINFO Database Record
