Quality of Life in Binge Eating Disorder.

Disease specific quality of life measure. The EDQLS consists of 40 items across 12 subscales and takes 2-11 minutes (mean 5 minutes) to complete. Each item is rated on a five-point Likert scale from 'strongly disagree' (scored as 1) to 'strongly agree' (scored as 5), with a higher score indicating better HRQoL (minimum score 40; maximum score 200). The 12 subscales are: cognitive, education/vocation, family and close relationships, relationships with others, future outlook, appearance, leisure, psychological, emotional, values and beliefs, physical, and eating. Each subscale contains three items, except for the 'eating' subscale which has six items. The EDQLS software includes an automatic scoring program that converts all item responses to a total score (some subscales require reverse scoring prior to summing).
