Psychological responses to body shape exposure in patients with bulimia nervosa.
One of the unresolved issues regarding research on bulimia nervosa concerns the question as to how patients diagnosed with bulimia nervosa respond to body image exposure. In addition, it remains unclear whether there are differential responses associated with different exposure techniques (e.g. in vivo exposure vs. exposure by visualization). The aim of the present study was to investigate psychological responses to body image exposure. Twenty participants diagnosed with bulimia nervosa (DSM IV) and twenty non-eating disordered individuals were exposed to their body image using a video recording (video confrontation). In addition, they were asked to imagine and describe the appearance of their body (imagery task). Results indicate that self-reported negative emotions increased in response to both, video confrontation and imagery task, in the clinical as well as in the control group. Furthermore, video confrontation led to more pronounced group differences than exposure by visualization (imagery task). Participants diagnosed with bulimia nervosa took less time to describe their waist, hips and bottom compared to non-eating disturbed controls. This last result could be interpreted in terms of avoidance behavior and other mechanisms during body image exposure.
