Confirmatory Factor Analysis of the Youth Psychopathic Traits Inventory in a Sample of Portuguese Adolescents
Abstract
This paper’s purpose consists in confirming the factorial structure, as well as, the evaluation of the psychometric
properties of the Youth Psychopathic Traits Inventory
(YPI), according to Confirmatory Factor Analysis procedure.
The YPI is composed of 10 dimensions that further
represent three hypothesized facets of the classical
description of psychopathy: callousness, interpersonal
manipulation and impulsiveness. A sample of 500
adolescents aged 12 to 18 (M ¼ 14.87; SD ¼ 1.67) from
northern Portugal participated in this study. The results
generally confirmed the factorial structure of the YPI in this
sample, with some qualifications.
