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

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 construc t validity of four narcissism scales: the Margolis-Thomas Measure of Narcis sism (MT; H. D. Margolis & V. A. Thomas, 1980), the Narcissistic Personalit y Disorder Scale (NPDS; H. U. Ashby, R. R. Lee, & E. H. Duke, 1979), the Na rcissism-Hypersensitivity subscale of the MMPI, Scale 5, Masculinity-Femini nity (NHMF; K. Serkownek, 1975), and the Narcissistic Personality Inventory (NPI; R. Raskin & C. S. Hall, 1979). The present analysis included the rev ised NPI and its factors along, with four measures of satisfaction and a nu mber 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 nee d to achieve, and inversely with all four satisfaction scales. Contrasts be tween 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 psycholo gical continuum related to adjustment.
