How is narcissistic personality disorder diagnosed?

A mental health professional such as a psychologist or psychiatrist (psychotherapist) can determine if you have key symptoms of NPD. Your psychotherapist will give you questionnaires and then talk with you.

You’ll go over what’s causing you distress. The focus will be on long-term patterns of thinking, feeling, behaving and interacting with others. Your psychotherapist will also identify and rule out any other mental health conditions.

Can I take a test to see if I have narcissistic traits?

Your psychotherapist may give you personality tests to see if you have narcissistic traits. The tests are just questions you answer honestly. They give your psychotherapist better insight into how you think and feel. Tests include:

  • Personality diagnostic questionnaire-4 (PDQ-4).
  • Millon clinical multiaxial inventory III (MCMI-III).
  • International personality disorder examination (IPDE).
