Body experience is of special importance during adolescence. The questionnaire to assess the own body (Fragebogen zur Beurteilung des eigenen Körpers) is one of the most frequently used German questionnaires in the field of body experience. The aim of the study is to test the application of the questionnaire in the age range of adolescence and to provide norm values. A sample of 346 adolescents between 12 and 20 years was tested. With the exception of three items which concern sexuality the questionnaire was well applicable in this age group. Gender differences among adolescents are more pronounced than among adults. Girls compared to boys showed higher mean values in the scales unsecurity and accentuation of the own body, while the mean values were lower in the scale attractivity/self esteem. Norm values are derived separately for boys and girls.
