Further assessment of the construct validity of four measures of narcissism: replication and extension

CT. The authors build on earlier research by L. S. Mullins and R. E. Kopelman (1988) and R. E. Kopelman and L. S. Mullins (1992) to reexamine the construct validity of four narcissism scales: the Margolis-Thomas Measure of Narcissism (MT; H. D. Margolis & V. A. Thomas, 1980), the Narcissistic Personality Disorder Scale (NPDS; H. U. Ashby, R. R. Lee, & E. H. Duke, 1979), the Narcissism-Hypersensitivity subscale of the MMPI, Scale 5, Masculinity-Femininity (NHMF; K. Serkownek, 1975), and the Narcissistic Personality Inventory (NPI; R. Raskin & C. S. Hall, 1979). The present analysis included the revised NPI and its factors along with four measures of satisfaction and a number of other previously assessed variables. The MT exhibited the strongest validity, correlating positively with conceptually related constructs such as Machiavellianism, nonsignificantly with unrelated measures like the need to achieve, and inversely with all four satisfaction scales. Contrasts between the NPI and NPDS and NHMF seemed to parallel recent differentiations between overt and covert narcissism, but data for the NPI factors suggested instead that the four narcissism scales helped describe a complex psychological continuum related to adjustment.
