Abstract

In order to assess the reliability, factorial validity, and criterion validity of the Personality Inventory for DSM-5 (PID-5) among adolescents, 1,264 Italian high school students were administered the PID-5. Participants were also administered the Questionnaire on Relationships and Substance Use as a criterion measure. In the full sample, McDonald’s ω values were adequate for the PID-5 scales (median ω =.85, SD =.06), except for Suspiciousness. However, all PID-5 scales showed average inter-item correlation values in the.20-.55 range. Exploratory structural equation modeling analyses provided moderate support for the a priori model of PID-5 trait scales. Ordinal logistic regression analyses showed that selected PID-5 trait scales predicted a significant, albeit moderate (Cox & Snell R2 values ranged from.08 to.15, all ps <.001) amount of variance in Questionnaire on Relationships and Substance Use variables.
