اثر مواجهه طولانی مدت با تصویر بدنی و مکرر در اختلال پرخوری افراطی

Objective: The purpose of the present study was to investigate psychological mechanisms associated with prolonged and repeated body image exposure. Method: In an experimental design, 30 female volunteers diagnosed with binge-eating disorder (BED) (DSM-IV) and 30 non-eating-disordered controls (NC) were exposed to their physical appearance in a mirror. The confrontation procedure was guided by a standardized interview manual and took place on two separate days. Self-reported mood, appearance self-esteem, and frequency of negative cognitions were assessed repeatedly throughout the experiment. Results: During body image exposure sessions, binge-eating-disordered individuals showed significantly lower mood than controls while appearance self-esteem was diminished in both groups. During the second body image exposure session, higher levels of mood and appearance self-esteem were observed in both groups, and negative cognitions occurred less frequently. Conclusion: Results are discussed with regard to the therapeutic use of body image exposure.
