Body image avoidance is conceptualised as a behavioural manifestation of body image disturbance, and describes efforts to avoid confrontation with one's own body. While studies have provided hints that body image avoidance in adulthood contributes to the development and maintenance of eating disorders, so far, there are no corresponding findings for adolescence. The Body Image Avoidance Questionnaire (BIAQ) is the most widely used international questionnaire for measuring body-related avoidance behaviour. As its German version has only been validated in an adult sample, the aim of the present study is to statistically test the questionnaire in adolescents with eating disorders. In total, N = 127 female adolescents, including n = 57 with Anorexia Nervosa, n = 24 with Bulimia Nervosa, and n = 46 healthy controls, answered the BIAQ as well as various other instruments for assessing body image disturbance and eating disorder symptoms. The factor structure assumed for the original English version, comprising the higher- order factor ``body-related avoidance behaviour'' and the 4 subfactors ``clothing'', ``social activities'', ``eating restraint'' and ``grooming and weighing'', was confirmed by a confirmatory factor analysis. With the exception of the scale ``grooming and weighing'', all scales showed mostly acceptable internal consistencies, test-retest reliability, differential validity and construct validity. Due to their satisfying psychometric properties, the use of the BIAQ scales ``clothing'', ``social activities'' and ``eating restraint'' can be recommended in research and practice for adolescence.
