Abstract:
Body displacement, the theory that predicts that individuals with eating disorders will displace negative feelings about themselves onto their body, was tested experimentally in this study. Unrestrained eaters (n = 61), restrained eaters (n = 33), and individuals with eating disorders (n = 26) were randomly assigned to a control condition or an ineffectiveness induction. In the ineffectiveness condition participants were asked to recall and reflect on a past experience when they felt useless or incapable (i.e., ineffective). Results showed that individuals with eating disorders who were made to feel ineffective reported more implicit appearance/body concern than those in the control condition. Unrestrained and restrained eaters did not show this effect. This is the first experimental study to support body displacement theory. These data can be used clinically to educate and encourage patients with eating disorders to address thoughts and feelings related to ineffectiveness directly, instead of displacing this distress onto their body and potentially perpetuating their eating disorder.
