What does viewing a pro-anorexia website do? An experimental examination of website exposure and moderating effects

Int J Eat Disord. 2007 Sep;40(6):537-48. doi: 10.1002/eat.20396.

Abstract

Objective: This study experimentally examined the effects of viewing a pro-anorexia website.

Method: Following construction of a prototypic pro-anorexia website, 235 female undergraduates were randomly assigned to view either the pro-anorexia website or one of two comparison websites related to female fashion (using average-sized models) or home décor. Post-website affect, cognitions, and behavioral expectations were examined along with moderator effects.

Results: Study participants exposed to the pro-anorexia website had greater negative affect, lower social self-esteem, and lower appearance self-efficacy post-website than those who viewed a comparison website. Additionally, they perceived themselves as heavier, reported a greater likelihood of exercising and thinking about their weight in the near future, and engaged in more image comparison. Minimal support was found for moderator effects.

Conclusion: Results provide an empirical basis for concern (expressed by clinicians, researchers, the media) that pro-anorexia websites are a troubling new form of thin-ideal exposure that warrants further examination.
