[Validation of the German translation of the Eating Disorders Quality of Life (EDQOL)].

The aim of the study was the translation and validation of a disease-specific questionnaire (Eating Disorders Quality of Life, EDQOL) to measure the health-related quality of life of eating-disordered patients. 195 patients with eating disorders and 109 healthy controls were examined by EDQOL and other instruments (SF-12, EDI, FKB-20, SEED, BSI, IIP-D and SOC-13). The EDQOL total score proved to have a high internal consistency. The four factorial structure of the original version was confirmed. There were indications of very good construct validity and a good sensitivity for change. For the first time, in the German-speaking part there is an economic, reliable and valid instrument that assesses the specific health-related quality of life for patients with eating disorders which is recommended for use in research as well as in clinical settings.
