In this article, we describe the development and validation of a short (10 item) but comprehensive self-report measure of childhood narcissism. The Childhood Narcissism Scale (CNS) is a 1-dimensional measure of stable individual differences in childhood narcissism with strong internal consistency reliability (Studies 1-4). The CNS is virtually unrelated to conventional measures of self-esteem but is positively related to self-appraised superiority, social evaluative concern and self-esteem contingency, agentic interpersonal goals, and emotional extremity (Study 5). Furthermore, the CNS is negatively related to empathic concern and positively related to aggression following ego threat (Study 6). These results suggest that childhood narcissism has similar psychological and interpersonal correlates as adult narcissism. The CNS provides researchers a convenient tool for measuring narcissism in children and young adolescents with strong preliminary psychometric characteristics.

This experiment tested how self-views influence shame-induced aggression. One hundred and sixty-three young adolescents (M 5 12.2 years) completed measures of narcissism and self-esteem. They lost to an ostensible opponent on a competitive task. In the shame condition, they were told that their opponent was bad, and they saw their own name at the bottom of a ranking list. In the control condition, they were told nothing about their opponent and did not see a ranking list. Next, participants could blast their opponent with noise (aggression measure). As expected, narcissistic children were more aggressive than others, but only after they had been shamed. Low self-esteem did not lead to aggression. In fact, narcissism in combination with high self-esteem led to exceptionally high aggression.

Recent field studies have revived the hypothesis that low self-esteem causes aggression. Accordingly, we reanalyzed the data from a previous experiment and conducted a new experiment to study direct physical aggression in the form of blasting a fellow participant with aversive noise. We also conducted a field study using a measure of indirect aggression in the form of a consequential negative evaluation. High narcissists were more aggressive than others but only when provoked by insult or humiliation and only toward the source of criticism. The combination of high self-esteem and high narcissism produced the highest levels of aggression. These results support the view of aggression as stemming from threatened egotism and are inconsistent with the hypothesis that low self-esteem causes either direct or indirect aggression.

Narcissism is a personality trait characterized by a sense of superiority and a desire for respect and admiration from others. A common belief, both in psychology and in popular culture, is that narcissism represents a form of excessive self-esteem. Psychologists, including ourselves, have labeled narcissism as "an exaggerated form of high self-esteem," "inflated self-esteem," and "defensive high self-esteem." We review research that challenges this belief by showing that narcissism differs markedly from self-esteem in its phenotype, its consequences, its development, and its origins. Drawing on emerging developmental-psychological evidence, we propose a distinction between narcissism and selfesteem that is based on the divergent socialization experiences that give rise to them. This proposal clarifies previous findings, stimulates theory development, and creates opportunities for intervention to concurrently raise self-esteem and curtail narcissism from an early age.
