The Eating Disorders Quality of Life Scale EDQLS was recently developed to allow for measurement of broader outcomes. We examined responsiveness of the EDQLS in a longitudinal multi-site study. Methods The EDQLS and comparator generic QoL scales were collected in person at baseline and 3 and 6 months from 130 participants mean age years range 14-60 in 12 treatment programs in four Canadian provinces. Total score differences across the time points and responsiveness were examined using both anchor-and distribution-based methods. Results 98 75 and 85 65 responses were received at 3 and 6 months respectively. No statistically significant differences were found between the baseline sample and those lost to follow-up on any measured characteristic. Mean EDQLS total scores increased from 110 SD 24 to SD 29 at 3 months and 129 SD 28 at 6 months and the difference by time was tested using a general linear model GLM to account for repeated measurement p .001 . Responsiveness was good overall Cohen s d .61 and .80 and confirmed using anchor methods across 5 levels of self-reported improvement in health status p .001 . Effect sizes across time were moderate or large for for all age groups. Internal consistency Chronbach s alpha .96 held across measurement points and patterns of responsiveness held across subscales.
