Comparing the construct validity of scales derived from the Narcissistic Personality Inventory: A reply to Rosenthal and Hooley (2010)
نویسندگان
چکیده
Rosenthal and Hooley (2010) suggested that the Narcissistic Personality Inventory (NPI) includes items that are tangential to narcissism. They demonstrated that the removal of these items resulted in scores that are not confounded by self-esteem. We tested whether NPI scales derived from Rosenthal and Hooley’s included (NPI-N) and excluded (NPI-X) items manifest divergent relations with self-esteem, entitlement, distress, NPD, and general traits in two samples of undergraduates. The scales generated similar patterns of correlations, although the NPI-N items were more strongly related to (dis)Agreeableness, whereas the NPI-X items were more strongly related to Extraversion. Ultimately, the NPI-X items bore significant relations to constructs central to grandiose narcissism and do not seem to have caused problems in the assessment of narcissism. 2010 Elsevier Inc.
