Addressing reporting heterogeneity in visual analogue scales: a double-index model approach using anchoring vignettes
Abstract In this study, we propose several methods to account for reporting heterogeneity in self-reported data coming from Visual Analogue Scales (VAS) using corresponding VAS-based anchoring vignettes. Though widely used as a measurement tool in many disciplines, VAS may suffer from reporting hete...
