Modeling the Structure of the Triarchic Psychopathy Measure: Conceptual, Empirical, and Analytic Considerations [link]Paper  doi  abstract   bibtex   
This study sought to characterize the factor structure of the Triarchic Psychopathy Measure (TriPM) using data from a sample of 1,082 community-dwelling Italian adults. Exploratory structural equation modeling (ESEM) was used to compare the fit of a bifactor model for each TriPM scale, in which specific-content factors were specified along with a general factor, with the fit of a single, general-factor model. Robust weighted least square (WLSMV) ESEM supported a bifactor latent structure of the TriPM items for all individual scales. When we jointly factor analyzed the 58 TriPM items, a WLSMV ESEM three-factor structure showed adequate fit; the three ESEM factors were akin to TriPM Boldness, Meanness, and Disinhibition theoretical dimensions, respectively, and could be effectively replicated across gender subgroups. Our findings support the three-factor structure of TriPM items, at least in Italian community-dwelling adults, and provide further evidence for the construct validity of the TriPM.
