| Abstract | PURPOSE: Disordered eating is common for all ages and sexes in the general population. However, only some individuals are known to develop clinically relevant eating disorders. There is a critical need of efficient, reliable and valid screening instruments to measure disordered eating for the general population. The Eating Attitudes Test was shortened into an 8-item-version to screen individuals at high risk of developing clinical eating disorders in a general population sample. METHODS: Psychometric properties (Cronbach's , construct and concurrent validity and factor structure), cutoff scores (with sensitivity, specificity, positive and negative predictive value) and norms were determined in a representative sample of the German population (N=2527). Factorial validity was investigated using item response modeling. RESULTS: Results confirmed reliability and validity of the questionnaire. Internal consistency and convergent validity were good. Analysis revealed different cutoff points for male and female participants. Values for sensitivity and specificity were satisfying and the positive predictive value was higher compared to other short screening instruments for disordered eating. Factorial analysis revealed a one-factor solution with an excellent model fit. The elimination of one item was discussed. Gender- and age-specific norms are reported. CONCLUSIONS: Overall results indicated that the EAT-8 is an efficient instrument suitable for screening purposes in large general population samples. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
