Validity of the MMPI Narcissistic Personality Disorder Scale

Abstract

The MMPI Narcissistic Personality Disorder Scale, the Tennessee Self-concept Scale, and a Profile Questionnaire were administered to 100 undergraduate students in the Los Angeles area. The MMPI scale significantly differentiated between people on the Tennessee Self-concept Scale, involvement in a satisfying love relationship, and frequency of nightmares. These findings are consistent with the theories of Kohut and Kernberg.
