Abstract

Objective: We examined whether media exposure and media-induced stress contributed to eating disorder behaviors immediately and over the course of a day in women with anorexia nervosa (AN). Method: Women with AN (N = 118) completed a 2-week ecological momentary assessment protocol during which they reported on exposure to food, shape, or weight-related media, associated stress, and eating behaviors. Results: Food, weight, or shape-related media exposure alone did not predict more frequent daily eating disorder behaviors. However, stress associated with media exposure was prospectively associated with a greater likelihood of binge eating and vomiting at the next assessment point. In addition, media-induced stress increased the probability of restrictive eating and fluid intake, vomiting, and laxative abuse across the day. Discussion: Media-induced stress may contribute to increased eating disorder behaviors in women with AN, as women who saw a media image and reported this experience as stressful were more likely to engage in momentary binge eating or vomiting. Reducing stress associated with viewing media images could be a potential target for therapeutic intervention with disordered eating.
