Objectives:
To assess the responsiveness of the Health-Related Quality of Life for Eating Disorders questionnaire version-2 (HeRQoLEDv2) and present the psychometric characteristics of a new binge domain.
Study Design And Setting:
Patients with an eating disorder completed the HeRQoLEDv2, the Eating Attitudes Test-26, Short Form Health Survey-12, and two items from the Eating Disorder Inventory-2, at baseline and after 1 year. At the second assessment, patients completed the HeRQoLEDv2, as part of the battery of tests, along with health transitional questions. Validity and reliability analyses of the new binge domain were performed. Responsiveness was evaluated using distributional and anchor-based approaches, comparison of mean changes, mean change correlations, the minimal detectable change (MDC) at the individual and group level, and the minimal important difference (MID).
Results:
Items in the binge domain loaded above 0.40. Cronbach alpha was 0.82. Regarding responsiveness, the mean changes detected by the HeRQoLEDv2 correlated above 0.30 with the criterion measures. Patients who reported improvement showed significant changes, and effect sizes above 0.30. The MDC(90%ind) was larger than the MID.
Conclusion:
The HeRQoLEDv2 includes the new binge domain. It responded to change at the group level. Further research regarding the MID is needed.
