Assessing Internal Responsiveness of QLU-C10D: A Comparative Analysis of Effect Size Measures

This study assesses the internal responsiveness of the QLU-C10D questionnaire between T0 and T2. To assess responsiveness, effect size (ES) is utilized. In order to address the debate surrounding the most appropriate measure of response magnitude for calculating ES, both standardized response mean (SRM) and change ratio (CR) are also employed.
