TRECHERA, JOSÉ LUIS; MILLAN VASQUEZ DE LA TORRE, GENOVEVA and FERNANDEZ MORALES, EMILIO. AN EMPIRICAL STUDY OF NARCISSISTIC PERSONALITY DISORDER (NPD). Act.Colom.Psicol. [online]. 2008, vol.11, n.2, pp. 25-36. ISSN 0123-9155.
This research aims at getting deep into the description and assessment of narcissistic personality disorder (NPD). Firstly, we define NPD by four characteristics: false self-image, lack of empathy, sensitivity to criticism and disturbances in interpersonal relationships. Taking from a sample of 1025 persons, we elaborated a 15items test to measure NPD with three factors: narcissism, Machiavellianism and dominance. At the same time, we elaborated two tests, lack of empathy and exhibitionism, related to narcissistic pathology. The results confirm the multifactor structure of the concept (NPD), finding important differences between NPD in the Spanish and the American contexts as well as significant relations with the Mehrabian and Epstein Tests, the Ma4 Scale by Harris and Lingoes and the NPI by Raskin and Hall. In addition, there were significant relations between NPD and different variables such as age and gender.
