Numerical Rating Scale (NRS)

Bild
​nrs_italian_28nov2022.pdfnrs_german_28nov2022.pdfThe NRS is comprised of one item and represents the numbers 0 (“no itch”) to 10 (“worst imaginable itch”). Subjects are asked to rate the intensity of their itch using this scale. It features high reliability and concurrent validity and is a popular choice for all patients due to its simple format.

  • Time needed for completion: 1 minute
  • Validated in English, French, German, Italian, Polish, Russian, Spanish and Turkish (click to download)
  • Also available in Japanese and Czech (click to download)
  • It can be interpreted as follows:    NRS= 0 - no pruritus
                                                                       NRS <3 - mild pruritus
                                                                       NRS  >  3< 7 - moderate Pruritus
                                                                       NRS > 7< 9 - severe Pruritus
                                                                       NRS > 9 - very severy pruritus
