Study of Relationship between Identity Styles and Personality Disorders in University Students

The aim of this study was to investigate the relationship between identity styles and personality disorders and to determine the role of identity styles in predicting personality disorders. For this purpose, Berzonsky's ISI, and Millon's test were distributed to all 520 freshmen in the Humanities Faculty (excluding the Faculty of Management) at Yazd University. A total number of 332 questionnaires were returned. Results showed that regression coefficients for predicting scores in 9 out of 10 personality disorders were significant. In the group A of personality disorders (Paranoid, Schizoid, and Schizotypal), multiple coefficients were 0.176, 0.229 and 0.262 respectively (p<0.05). In the group B of personality disorders (Antisocial, Borderline, Narcissistic, and Histrionic) all regression coefficients excep with Histrionic personality disorder, were significant. (0.222, 0.305, 0.363 and 0.168 respectively). In the group C of personality disorders, all coefficients were significant. Coefficients were 0.348 for avoidant, 0.306 for OCD, and 0.439 for dependent. Results are discussed on the basis of Berzonsky's theory on identity styles and other relevant theories and studies.
