Abstract
While the use of PROMs in clinical research continues to grow and user interface design evolves steadily, newly developed PROMs use mostly standard scale types such as Numeric Rating Scale(NRS), Verbal Response Scale(VRS), Visual Analog Scale(VAS) in a paper-based original design. This research validated a modern design for the VRS and tested it against the standard VRS-design of the EQ-5D-5L to encourage instrument developers to utilise modern design approaches supported by new technology.
