Toward an assessment of the construct validity of four measures of narcissism

In recent years there has been growing conceptual interest in narcissism, coupled with the rapid development of several paper and pencil measures. Clearly, construct validation should be performed prior to the adoption of any measure. This study reports on the construct validation of four scales that purport to measure narcissism. A conceptual definition of narcissism is provided, and a number of empirical analyses are performed, including examination of internal consistency reliabilities, intercorrelations among the four narcissism scales, and correlations with related and unrelated measures. Three of the four scales were found to be consistently related to each other, and demonstrated similar patterns of substantive and discriminant validity. A factor analysis, performed to examine the structure of the four narcissism measures, suggests four dimensions: desire for attention, admiration, and authority; feelings of inadequacy, unhappiness, and worry; disturbances in interpersonal relationships (exploitation, sense of entitlement, lack of empathy); and sensitivity to criticism and defeat. Implications of the results are discussed.
