Body-related film clip triggers desire to binge in women with binge eating disorder.
Previous research suggests that excessive influence of shape or weight concern on self-evaluation is strongly associated with psychological functioning in women with binge eating disorder (BED). However, little is known so far about its direct influence on binge episodes. In an experimental study, 27 women with BED (DSM-IV) and 25 overweight healthy controls watched a body-related film clip. Ratings of the desire to binge and mood were assessed prior to and at the end of the film clip. Additionally, measures of heart rate, finger pulse and electrodermal activity were obtained. Main results revealed a significant increase in the desire to binge, sadness and anxiety, as well as a significant increase in non-specific skin conductance fluctuation on the body-related clip in the group of BED only. The results underline the importance of shape and weight concerns in BED.
