Description: The present three studies aim to explain how disordered eating is related to identity confusion. The following propositions were made: (1) binge eating is a means of escaping or masking uncertainty about identity that dieters feel unable to cope with adaptively, and (2) the preoccupation with food and body weight issues seen in restrained eaters becomes an "identity substitute" for some young women, providing them with concrete goals that give them a sense of purpose, direction, and uniqueness in their lives that might be otherwise lacking. In three studies (Ns = 74, 63, & 103), Restrained eaters (Rs) and Unrestrained eaters (URs) were randomly assigned to one of three conditions that manipulated perceived certainty about identity to determine its effect on subsequent food intake. Further, Ss rated the extent to self-generated goals were central to their identities. All studies found support for the two main hypotheses: (1) Rs responded to an identity threat by overeating whereas URs' intake did not differ across conditions, and (2) Rs' diet-related goals were more central to their identities than were URs' diet-related goals. However, in contrast to hypotheses, there was little evidence that this overemphasis on diet-related goals had negative consequences for Rs' identities in other more adaptive domains (i.e., in terms of career- or school-related goals). Moreover, while there was some evidence that Rs were more likely to employ a diffuse-avoidance identity style and showed less identity commitment overall, the findings regarding Rs' relative degree of identity confusion were inconsistent across studies. Two studies also found that giving Rs a chance to reaffirm their identities, even after presented with an identity threat, can prevent disinhibited eating. Implications in terms of disordered eating and possibilities for further research are explored.
