Bifactor Modeling

The current study examines a bifactor model for the Youth Psychopathic Traits Inventory (YPI) in a Dutch community sample of adolescents ( N = 2,874). The primary goal was to examine the latent structure of the YPI with a bifactor modeling approach. Furthermore, the study examines the dimensionality and measurement invariance of the YPI. Results show that a bifactor model at subscale level fits the YPI best. The general psychopathy factor influences the 10 subscales of the YPI strongly, indicating that the YPI seems to be rather unidimensional than multidimensional. Nevertheless, the dimensions still explain nearly one third of the variance found. Findings imply that the bifactor model of the YPI should be used when examining relations with outcome variables, with a focus on the total score of the YPI, while factor scores should be reported with caution. Furthermore, the bifactor model appears invariant for gender, age, and ethnic background.

Youth Psychopathic Traits Inventory

Abstract Background The aim of the current study is to examine the psychometric properties of the German Version of the Youth Psychopathic traits Inventory-Short Version (YPI-S). Methods A sample of 856 adolescents (age: 15–19) from the German-speaking part of Switzerland was included. All participants completed the 50-item YPI, of which we derived the 18 items of the YPI-S. Furthermore, participants completed the Massachusetts Youth Screening Instrument-Version-2 (MAYSI-2), as well a self-report delinquency questionnaire. Results We were able to replicate a three-factor structure and found moderate to good internal consistency for the total score as well as for the three dimensions of the YPI-S. Measurement invariance across gender was established. Furthermore, we found positive small to medium correlations with both internalizing and externalizing mental health problems, substance abuse problems, and offending behavior. Conclusions Our results suggest that the German version of the YPI-S is a reliable and valid screening instrument for psychopathic traits in both boys and girls from the general population in the German-speaking part of Switzerland.
