Research has also examined the two main factors of psychopathy. The interpersonal-affective traits (referred to as Factor 1) include deceitfulness, superficial charm, manipulativeness, deficient empathy, and lack of remorse (Hare, 2003). The impulsive-antisocial traits (referred to as Factor 2) are characterized by impulsivity, irresponsibility, weak behavioral control, and criminal versatility (Hare, 2003). Alternative three or four factor models split the original two factors into facets. The three facet model focuses on the interpersonal (e.g., deceit), affective (e.g., shallow affect), and lifestyle (e.g., impulsivity) facets (Cooke & Michie, 2001). A fourth facet, the antisocial facet, is included in the four-facet model, and assesses criminal involvement and versatility (Hare, 2003). Whether using a three-facet, four-facet or two-factor model, psychopathy factors show different relationships with a variety of constructs (e.g. Skeem, Miller, Mulvey, Tiemann & Monahan, 2005).
