This test is not a diagnostic instrument for a personality disorder. It will not tell you if you have narcissistic personality disorder; what this test documents is the taker's levels of various narcissistic traits. This test was not created by Dr. Drew Pinsky; it is a standard test avaliable to anyone.

In taking this test, you'll notice that it's sometimes difficult to choose between the two choices offered to you. You may feel that neither, or both, apply. This is what social scientists call a forced choice. Although you may feel ambivalent about the choices available to you, the one you do choose has meaning. There are no time constraints for the evaluation, but you should take it in a single sitting, without asking anyone for help or clarification.
