[Reliability survey and standardization of the narcissism inventory based on a healthy sample].
The German "Narzissmusinventar" (Narcissism Inventory, Deneke and Hilgenstock 1989) was used in many clinical studies, but until now there was only very little data about healthy controls. Therefore, this study will survey data from a bigger healthy sample, examine the influence of sex and age and study the retest-reliability. Data of 273 healthy controls was gathered in a dentist practice and 100 of the participants filled out the questionnaire for a second time after one month. Except for the scale "smallness self", all scales revealed fairly good reliability values (retest and internal consistency). Also the item-total correlations and the connection between the items and the scales were satisfying. There were significant differences between men and women in 9 of the 18 scales. The group of young people (ages 15 to 20) differed significantly from the older age groups in 13 scales. These young probands described themselves as more anxious and more driven by emotions. Therefore separate evaluations for this group are suggested. Overall, the good psychometric properties of the Narcissism Inventory have been verified.
