Using self-esteem to disaggregate psychopathy, narcissism, and aggression

Past research offers conflicting conclusions regarding the associations between self-esteem, psychopathy, narcissism, and aggression. The current study clarified these associations by examining self-esteem level and stability as it relates to the factors of psychopathy and narcissism predicting aggression. Self-report assessments were administered to 118 undergraduates. While self-esteem instability was not related to psychopathy or narcissism, it was positively correlated with aggression. Additionally, those with the healthier aspects of narcissism and Factor 1 features of psychopathy had high self-esteem and less aggression, while those with more pathological narcissism and Factor 2 features of psychopathy had lower self-esteem and more aggression. Specifically, the relationship between psychopathy Factor 1 and aggression was partially mediated by lower self-esteem.

► Positive correlations for healthy narcissism, Factor 1 psychopathy and self-esteem.
► Pathological narcissism and Factor 2 associated with low self-esteem and high aggression.
► Self-esteem instability and Factor 2 predict aggression.
► Relationship between Factor 2 and aggression is partially mediated by low self-esteem.
► Assess self-esteem in risk and treatment of pathological narcissism and Factor 2 traits.
