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.

Personality psychology and problem behaviors: HIV risk and the five-factor model.

Studies of personality and problem behaviors may begin with analyses of the problem and develop hypotheses about personality traits that might be relevant; or they may begin with models of personality and explore links to behavior. Because it is well validated and relatively comprehensive, the Five-Factor Model (FFM) of personality lends itself to systematic exploratory studies that may sometimes lead to unanticipated findings. In this article, we review a program of research in a high-risk, disadvantaged population that illustrates the utility of the FFM in understanding health risk behavior. Previous analyses showed that behavior associated with the risk of HIV infection can be predicted from the personality dispositions of Neuroticism and (low) Conscientiousness.

Prospects for the assessment of normal and abnormal interpersonal behavior.

The Interpersonal Adjective Scales (IAS) and the Inventory of Interpersonal Problems (IIP) are current representatives of a long-standing tradition and their use as assessment instruments is expected to become increasingly widespread in the near future and beyond. The IAS is a direct descendent of the interpersonal circumplex tradition and is characterized by an extraordinarily close relation between theory and method in the assessment of both normal and disordered personalities. The IIP stems from a more recent conceptual distinction between psychiatric symptoms and problems of living that has been linked directly to the interpersonal circumplex. This review is meant to alert clinicians to promising supplements to traditional intrapsychic and symptomatic psychodiagnostic batteries.
