ارتباط بین دو جنبه خودشیفتگی و علائم اختلال تغذیه ای

The current study sought to examine the relationships between two facets of narcissism (vulnerable and grandiose) and eating disorder symptoms. Based upon previous research (Davis, Claridge, & Cerullo, 1997), it was predicted that the vulnerable narcissism facet would be more strongly associated with eating disorder symptoms because of the tendency for vulnerable narcissists to base their self-worth on their appearance (Zeigler-Hill, Clark, & Picard, 2008). The hypotheses were tested cross-sectionally in a sample of 355 male and female undergraduate students. Results generally conformed to prediction, in that vulnerable narcissism tended to be positively correlated with eating disorder symptoms, and this relationship was partially mediated by self-worth that is contingent upon physical appearance. Our findings are consistent with the notion that vulnerable narcissism is a risk factor for eating disorder symptoms because it is associated with a drive to improve self-worth through the enhancement of physical appearance.

The literature consistently reports a link between narcissism and eating disorder symptoms (Davis et al., 1997, Steiger et al., 1997, Steinberg & Shaw, 1997 and Waller et al., 2007). The current study sought to expand upon the extant literature by examining how two facets of narcissism (grandiose and vulnerable; Dickinson & Pincus, 2003) are related to eating disorder symptoms, and testing whether a specific contingency of self-worth (basing one's worth on appearance) mediates the relationship between vulnerable narcissism and eating disorder symptoms. This cross-sectional study was conducted in a sample of college undergraduate students. This may be a particularly relevant population in light of evidence that narcissism is rising in this age group (Twenge, Konrath, Foster, Campbell, & Bushman, 2008) and that this age group (18 to 21) is at the highest risk for the onset of eating disorders (Hudson, Hiripi, Pope, & Kessler, 2007).
