Explicit memory bias for positively valenced body-related cues in women with binge eating disorder.

Overweight women with and without binge eating disorder (BED) are characterized by a marked body dissatisfaction, which may in part be due to the negative comments about their weight. Weight-related teasing and discrimination is reported both by healthy overweight women and women with BED, whereas body dissatisfaction is markedly increased among women with BED. Therefore, a memory bias for negatively valenced body-related cues is suspected to occur as a mediating factor in women with BED. In an experimental study, 18 women with BED were compared to 18 overweight healthy female controls (HC) on a free recall task containing four word categories: positively valenced with and without body-related content and negatively valenced with and without body-related content. While both groups showed a bias towards negatively valenced shape-/weight-related words, women with BED retrieved positively valenced shape-/weight-related words significantly less often compared to overweight HC. Findings suggest that it may be the reduced ability to attend to positively valenced shape-/weight-related information, rather than the activation of negative body schemata that differentiates overweight women with BED from overweight women without BED. Results are discussed in the context of cognitive biases in the maintenance of body dissatisfaction. (c) 2010 Elsevier Ltd. All rights reserved.
