Narcissism, identification, and longitudinal change in psychological health: Dynamic predictions

The narcissist has been described as “dependent on others to provide confirmation of the grandiose ego ideal” (American Psychiatric Association. (1994). Diagnostic and statistical manual of mental disorders (4th ed.). Washington, DC: Author.). The present study shows how the combination of dependent identification and unhealthy narcissism leads to decreasing psychological health across 42 years of adulthood. Change in psychological health is studied in 156 participants of the Intergenerational Studies, Institute of Human Development, University of California, Berkeley. We predicted that longitudinal decline in psychological health, as assessed by longitudinal hierarchical linear modeling analyses of the California Personality Inventory v3 scale [Gough, H. G., & Bradley, P. (1996). California Psychological Inventory. Palo Alto, CA: Consulting Psychologists Press], would be predicted by the joint presence in early adulthood of maladaptive narcissism [Wink, P. (1992). Three narcissism scales for the California Q-set. Journal of Personality Assessment, 58, 51–66] and defensive identification [Cramer, P. (1991a). The development of defense mechanisms: Theory, research and assessment. New York: Springer-Verlag]. In contrast, we predicted healthy narcissism would be positively related to psychological health throughout adulthood. Predictions were confirmed via regression analyses including interaction terms, and are explained by the insoluble conflict that occurs when narcissistic gratification is dependent on the admiration of others, but the tie to others interferes with independent growth and accomplishment.
