The role of abnormal personality dimensions in predicting narcissistic personality traits

The proposed changes related to personality disorders in DSM-5 has increased the importance of paying attention to narcissism. The aim of this study is to investigate the role of abnormal personality dimensions in predicting narcissistic personality among students. For this purpose, in a descriptive correlational study, 300 undergraduate students were selected in a form of cluster random. They were tested in terms of narcissistic personality and abnormal personality dimensions. The Pearson correlation coefficient test results indicated that there is a significant correlation among most narcissistic components (power, glaring, hegemony, exploitation, arrogance, entitlement) and total score of narcissistic personality with abnormal dimensions of personality. However, self-sufficiency has no significant relationship with abnormal personality dimensions. The result of regression analysis indicated that except for self-sufficiency, none of the personality dimensions were anticipated. Different abnormal narcissistic personality dimensions significantly predict narcissistic components, In the meantime, especially negative emotions, psychotictemperament and opposition had a greater role, however only opposition was betterable to predict the total score of narcissism. It seems that the presented profile in DSM-5 for diagnosis of narcissistic personality which has opposition as the criteria for the diagnosis of this disorder, mostly includes narcissistic, grandiose type. While other dimensions of abnormal character including negative affection and psychotic temperament are also involved in this disorder.
