The aim of this research was to validate two aspects of fragile high self-esteem: a combination of contingent and high (explicit) self-esteem and a combination of high explicit and low implicit self-esteem (i.e. incongruent high self-esteem), as well as to examine the relationship between these aspects of fragile self-esteem and narcissism. No convergence was found between contingent high and incongruent high self-esteem. The result was consistent regardless of the technique of measurement of implicit self-esteem. There was a limited evidence that individuals with narcissistic personality characteristics were characterized by high self-esteem contingent upon competences, but not by a combination of high explicit and low implicit self-esteem, as an aspect of fragile self-esteem. Also, individuals with low selfesteem more contingent upon competences showed higher levels of narcissistic characteristics than those who were not contingent in this domain.
