Test-retest reliability of the Eating Disorder Inventory 2

J Psychosom Res. 2006 Oct;61(4):567-9. doi: 10.1016/j.jpsychores.2006.02.015.


Objective: This study reports on findings concerning the test-retest reliability of the Eating Disorder Inventory 2 (EDI-2).

Methods: Three hundred twenty-seven female inpatients who met the DSM-IV criteria for eating disorders (anorexia nervosa, bulimia nervosa, or eating disorders not otherwise specified) and 209 inpatients with a diagnosis of depression, obsessive-compulsive disorder, anxiety disorder, or somatoform disorder took part in the study. The EDI-2 was administered to the patients at the beginning of inpatient therapy and a second time 7 days later.

Results: All 11 EDI-2 subscales showed significant test-retest correlations ranging from .81 to .89 in the eating disorder group and from .75 to .94 in the group with other diagnoses.

Discussion: The test-retest reliabilities for the EDI-2 subscales are relatively high, indicating a good and acceptable stability over time. These results provide further evidence that the EDI-2 is an instrument with good reliability for the assessment of eating disorder symptoms.
