Construct validity of psychopathy in a community sample: a nomological net approach.
The construct validity of psychopathy was examined within a sample of 326 male and female university students. The interpersonal circumplex served as a nomological net for the examination of convergences between psychopathy measures and convergent and discriminant validity with a measure of personality disorders was examined using a matrix approach. Measures included: (a) Antisocial scale of the Personality Assessment Inventory (Morey, 1991); (b) Self-Report Psychopathy scale (Hare, 1991); (c) Psychopathic Personality Inventory (Lilienfeld & Andrews, 1996); (d) Personality Diagnostic Questionnaire-4 (Hyler, 1994); and (e) Interpersonal Adjective Scales Revised-Big 5 (Trapnell & Wiggins, 1991). Results indicated (a) substantial convergence between psychopathy measures; (b) high convergent validity between psychopathy measures and antisocial personality disorder; and (c) high discriminant validity from other personality disorders. The prevalence of psychopathy within this non-forensic sample is also discussed.
