Negative body-related feedback is associated with increased body dissatisfaction. The English-language version of the Feedback on Physical Appearance Scale (FOPAS) is an instrument to assess verbal and non-verbal body-related feedback, but a German-language version has not been validated yet. The aim of this study was to evaluate the psychometric properties of its German-language version in a sample of adolescents with eating disorders (n=88) and in a sample of adolescents (n=123) and women (n=228) without eating disorders. Confirmatory factor analyses showed a moderate model fit from the English-language original study. All samples showed acceptable internal consistencies. The retest reliability was also mostly acceptable. Significant positive correlations with questionnaires on eating disorder symptoms (criterion validity), teasing (convergent validity) as well as the expected negative correlation with self-esteem indicated good validity. In addition, the FOPAS was able to differentiate between adolescents with and without eating disorders. To sum up, the German-language FOPAS appears to be suitable to assess verbal and non-verbal body-related feedback in research and practice.
