Hostile Attribution Biases in Vulnerable Narcissists Depends on the Socio-Relational Context

Narcissism, especially the vulnerable kind, is associated with anger and hostility. In a sample of outpatients, group psychotherapy ( N = 74) and community members ( N = 153), we replicated and extended previous work linking vulnerable, but not grandiose, narcissism to hostile attributions across different socio-relational contexts. We also examined if the level of ambiguity of social situations, assessed from the other-referent position, influences the relationship between vulnerable narcissism and attributing hostile intentionality, and whether narcissistic individuals distinguish hostile interpretations, depending on the level of ambiguity of the scene. In ambiguous vignettes, assessed from the self-referent position, higher levels of vulnerable narcissism were associated with a greater tendency to infer more attributions of hostile intentions with people with whom there was no close relationship (except for authority in the patient group). In the case of visual scenes, the positive relationship between vulnerable narcissism and attributed hostile intentionality appeared in accidental scenes, but not in hostile and ambiguous ones. In addition, the higher the vulnerable narcissism the lower the ability to differentiate between contextual nuances (e.g., the level of ambiguity). We replicated previous research indicating a relationship between vulnerable narcissism and hostile attribution bias, but shed new light on the phenomenon of this bias in that it appears to depend on the socio-relational context and the level of ambiguity of the situation.
