[Validation of the Essen Quality of Life-Index for Eating Disorders (ELI)].
The aim of this study was the validation of a short disease-specific questionnaire (ELI, Essen Quality of Life Index for Eating Disorders) to measure the health-related quality of life in patients with eating disorders. A total of 182 currently ill and former eating disordered patients and 87 healthy controls completed the ELI questionnaire as well as other reliable and valid instruments (EDQOL, SF-12, EDI-2, FKB-20, SEED, BSI, IIP-D and SOC-13). In addition, 46 eating disorder patients completed the same questionnaires at the end of therapy. The ELI proved to have a high internal consistency of α=0.96. As expected, one main factor was found with a high declaration of variance of 71.25%. There is also evidence for very good construct validity and good sensitivity for change. Therefore, the ELI is an economic, reliable and valid instrument that assesses disease-specific health-related quality of life of individuals with eating disorders. The questionnaire can be recommended for research as well as clinical care contexts.
