The stigma of clean dieting and orthorexia nervosa

BACKGROUND Although the stigma of eating disorders such as anorexia has been well established, little is known about the social consequences of "clean dieting" and orthorexia nervosa. In two studies, we examined the social stigma of clean dieting and orthorexia. METHOD In Study 1, participants read a vignette describing a woman following a "clean" diet, a woman with anorexia, or a control target (minimal information about the individual). In Study 2, participants read a vignette describing a woman with orthorexia, a woman displaying identical orthorexic behaviors but without the orthorexia label, a woman with anorexia, or a control target. Participants then rated the target individual on a range of measures assessing stereotypes, emotions, and behavioral intentions toward the target. RESULTS Study 1 found that the clean-dieting target was evaluated more negatively than the control target on some dimensions, but less negatively than the target with anorexia nervosa. Study 2 found that evaluations of the targets with orthorexia nervosa were more negative than evaluations of a control target, but did not differ from evaluations of the target with anorexia nervosa. Perceptions of the target's control over her behavior were associated with more positive evaluations (Studies 1 and 2), whereas perceptions of blame and responsibility for the condition were associated with more negative evaluations (Study 2). CONCLUSIONS Overall, these findings highlight the potential negative social consequences of clean dieting and orthorexia nervosa, and point to perceptions of control and blame as potential mechanisms underlying the stigma of these conditions.
