present a brief overview of the models that have been used by personality theorists to investigate the structure of personality characteristics / believe the circumplex model to be the strongest rival to the traditional hierarchical structure / applied structural equation modeling to data from 2 complementary studies to test J. S. Wiggins' theory that interpersonal personality disorders could be arranged around a circle similar to that earlier proposed by T. Leary for interpersonal traits
results indicated that the circumplex model provided a good fit for 5 (histrionic, dependent, schizoid, paranoid, and narcissistic) of the 10 Diagnostic and Statistical Manual of Mental Disorders-III-Revised (DSM-III-R) personality disorders and for 7 of these disorders that were originally proposed by Wiggins / further analyses indicated that a quasi-simplex model was the most appropriate for depicting the relationships among antisocial, borderline, avoidant, passive–aggressive, and compulsive disorders (PsycINFO Database Record (c) 2016 APA, all rights reserved)
