The central domains of personality pathology in psychiatric patients

Abstract

There is general agreement that the classification of personality disorders in DSM-IV is unsatisfactory. We systematically reviewed all studies that have analyzed patterns of personality disorder symptoms and signs in psychiatric patients; twenty-two papers were included in the final synthesis. There is reasonable consistency over the number and type of personality pathology traits reported despite differing samples, varying assessment methods, and different statistical manipulations. There are three or four high order traits; an externalizing factor incorporating borderline, narcissistic, histrionic, and antisocial traits (the latter is sometimes recorded as a separate trait); an internalizing factor incorporating avoidant and dependent traits; a schizoid factor; and often a compulsive factor. Using these domains of personality pathology would simplify classification, have higher clinical utility, and allow relatively easy translation of current research.
