Visual Analogue Scale (VAS)

Bild
The VAS is a scale consisting of a 10cm long line and a single question. Along with the NRS, it is most commonly used in clinical trials for measuring itch intensity and features high reliability and concurrent validity. The left end point represents “no itch” and the right end point the “worst imaginable itch”.
It can be interpreted as follows:  VAS 0= no pruritus
                                                            VAS < 3= mild pruritus
                                                            VAS ≥ 3-<7= moderate pruritus
                                                            VAS ≥ 7-<9 = severe pruritus
                                                            VAS ≥ 9= very severe pruritus
