title: [Validation of a German-language Version of the Body Checking Questionnaire (BCQ) in Adolescents with Anorexia and Bulimia Nervosa].
abstract: Body-related checking behavior, as a behavioral manifestation of a disturbed body image, fosters the development and maintenance of eating disorders. The Body Checking Questionnaire (BCQ) is the most commonly used questionnaire for measuring body-related checking behavior internationally. To date, validation studies are only available for adult populations. Therefore, the aim of this study was to statistically test the German-language version of the BCQ in adolescents. A total of N=129 female adolescents were examined, comprising n=57 with Anorexia Nervosa, n=24 with Bulimia Nervosa, and n=48 healthy female adolescents. A confirmatory factor analysis supports the subdivision of the BCQ into a general factor and the subfactors "overall appearance", "specific body parts" and "idiosyncratic checking", which was also found in the original version. The internal consistencies are good (α≥0.81), and the BCQ is able to differentiate well between adolescents with and without eating disorders. Significant correlations between the BCQ and other body image questionnaires point to a good convergent validity. The German-language BCQ thus constitutes a valid and reliable instrument for measuring body-related checking behavior among adolescents in clinical research and practice.
