To detect eating disorders and risky eating behaviour in early stages, screening tests are used. In order to examine as many adolescents as possible, these tests should be economic, i. e. as short as possible but at the same time they should fulfil the psychometric quality criteria. We compared the German version of the Eating Attitudes Test (EAT-26D) and the German version of the SCOFF test (which contains only five Yes-no questions) in a sample of 425 twelve year old girls and 382 boys from Thuringia, Germany. Although the EAT-26D reached higher psychometric properties, the SCOFF has been proved as a useful screening tool with a test-retest reliability of rtt = .73 and a maximum accuracy of 82% (area under the ROC curve). In reference to the EAT-26D (20 point cut-off) the sensitivity of the SCOFF was 78%, specificity 75%, positive predictive value 28%, and the negative predictive value, which is more relevant for screenings, was 96%. The construct validity reached r = .52.
