Paranoid personality has a dimensional latent structure: taxometric analyses of community and clinical samples.
Although paranoid personality is one of the most commonly diagnosed personality disorders and is associated with numerous negative life consequences, relatively little is known about the structural properties of this condition. This study examines whether paranoid personality traits represent a latent dimension or a discrete class (i.e., taxon). In Study 1, the authors conducted taxometric analyses of paranoid personality disorder criteria in a sample of 731 patients participating in the Collaborative Longitudinal Study of Personality Disorders project (Gunderson et al., 2000) who had been administered a semistructured diagnostic interview for personality disorders according to criteria of the Diagnostic and Statistical Manual of Mental Disorders (4th ed.; American Psychiatric Association, 1994). In Study 2, the authors conducted parallel analyses of the Paranoia scale of the Personality Assessment Inventory (PAI; L. C. Morey, 2007), using data from the PAI community and clinical normative databases. Analyses across both self-report and interview-based indicators offered compelling support for a dimensional structure. Additionally, analyses of external correlates in these data sets suggested that dimensional models demonstrated stronger validity coefficients with criterion measures than did dichotomous models.
