Social appearance anxiety is an unexplored concept in eating disorders (ED). It refers to social anxiety surrounding overall appearance, including body shape, and fear of negative evaluation by others. It is potentially relevant to those with bulimia nervosa (BN) as both social anxiety and body image disturbance are commonly experienced by patients. Thirty women with BN and forty healthy controls (HC) completed the Social Appearance Anxiety Scale (SAAS), a 16-item self-report questionnaire. ED cognitions and behaviours were assessed with the Eating Disorders Examination-Questionnaire. Women with BN have significantly higher SAAS scores than HC (z=-6.79, p<0.001). In BN, SAAS scores show significant positive correlation with global ED subscales and dietary restraint. In HC, SAAS scores are correlated with shape, weight, eating concern, and global eating disturbance subscales. Preliminary findings suggest the SAAS is potentially useful in future research concerning overall risk factors for eating disturbance and treatment outcome in BN.
