title: [A short version of the Narcissistic Personality Inventory (NPI-15): dimensionality and psychometric properties in a representative sample of the German population].
abstract: The Narcissistic Personality Inventory (NPI) is a commonly used measure of narcissism. This study administered a 15 item short version of the NPI (NPI-15). Central aims of the present study were to examine its dimensionality, and to provide data on its psychometric properties. NPI-15 and Hospital Anxiety and Depression Scale (HADS-D) were assessed in a representative sample of the German population (N=2,512). According to Scree-plot and model fit, a solution with 2 or 3 factors seemed feasible. Because of factor loadings and item-level associations to depression/anxiety we decided to favour a 2-factor-solution. 2 subscales reflecting different facets of narcissism were compiled (leadership ability/personality [LA/LP], grandiosity [G]). The psychometric properties of these scales were good (LA/LP) respectively unsatisfactory (G). The validity of the NPI-15 needs to be further studied.
