Interpersonal sensitivity, eating disorder symptoms, and eating/thinness expectancies

This study examined social -emotional and cognitive factors in relation to eating disorder symptoms in 84 female undergraduates. Sensitivity to criticism and rejection-sensitivity related to each other and to appearance-related sensitivity. Although both interpersonal and appearance sensitivity related to a drive for thinness, appearance sensitivity had the stronger relationship. Interpersonal sensitivity was significantly correlated with expectancies that dieting and thinness lead to overgeneralized self-improvement, but not with eating expectancies. After controlling for body mass index, interpersonal sensitivity, and appearance sensitivity, dieting/thinness expectancies were related to drive for thinness, and expectancies that eating helps to manage negative affect were related to symptoms of bulimia. Findings are discussed in terms of the potential role that interpersonal sensitivity and eating-related expectancies may play in the development and maintenance of eating disorders, as well as intervention approaches.
