Stigma of Binge-Eating Disorder in Hong Kong Chinese Adults: Effects of Weight Status, Diagnostic Labeling, and Etiological Explanations

Objective: Binge-eating disorder (BED) is a strongly stigmatized condition and is often complicated by weight stigma. Research on the intersection between BED and weight stigma is scarce especially in Chinese populations. The present study examined BED stigma in Chinese, whether BED stigma was independent from weight stigma, and whether diagnostic labeling and etiological explanations influenced the degree of BED stigma. Method: Using a between-subject experimental vignette study, 642 participants (mean age = 29.74 years, SD = 11.34) were randomly assigned to read one of the 18 vignettes, describing a character with information on BED symptoms, weight status, diagnostic labeling, and etiological explanations, followed by measures of stigma and help-seeking intentions. Results: The character with BED symptoms was ascribed more negative personality characteristics, elicited more negative affective reactions, and triggered greater desired social distance compared to the character without BED symptoms. No evidence for weight stigma was found nor for its interaction with BED stigma. The Cantonese diagnostic label of BED, kwong sik zing, was associated with lower levels of volitional stigma and greater help-seeking intentions than the diagnostic label of eating disorders, jam sik sat tiu, and the absence of labeling. The effect of etiological explanations was only significant in the univariate test, indicating that providing either a psychosocial or a biogenetic etiological explanation lessened the negative evaluations of personality characteristics. Discussion: The present study provided first evidence for BED stigma in Chinese. BED stigma appeared to be attributable to the presence of disordered eating behavior rather than the BED diagnosis.
