The Sociocultural Attitudes Towards Appearance Questionnaire (SATAQ) is widely used in the English-speaking countries as a measure of sociocultural influences on body image. Aim of this study was to provide validation data for three subscales of a boys' and girls' German version of the SATAQ (SATAQ-G). A sample of 819 male and 791 female Swiss adolescents completed the SATAQ-G internalization of body ideals, perceived pressure and awareness subscales. They also completed assessments of body dissatisfaction, weight and shape concerns, drive for thinness, weight and height. Factor analyses replicated the three subscales of the SATAQ for the boys' as well as for the girls' version. All three subscales showed good internal consistency. The internalization and pressure subscales indicated acceptable convergent validity. Awareness did not significantly predict body dissatisfaction. The SATAQ-G, particularly the subscales internalization and perceived pressure, seems to be a satisfactory measure of sociocultural influences on body image.
