5-points Verbal Rating Scale- Pain

Instrument Name: 5-points Verbal Rating Scale- Pain

Abbreviation: VRS

Points for Consideration:

In a Verbal Rating Scale (VRS) adjectives are used to describe different levels of pain. The respondent is asked to mark the adjective which fits best to the pain intensity (Haefeli and Elfering 2006). The item wording, response scale wording and recall period vary and are often developed to be study specific.

Description of Tool:

The 5-point Verbal Rating Scale (VRS) is a single item PRO used to measure pain intensity. The patient is asked to mark the adjective which fits best to the pain intensity ranging from "no pain at all" and "extremely intense pain" [descriptors used and recall period vary by study].

Response Scales: Response scale can vary by study. A 4-point VRS is most commonly used in scale comparison studies, and a 5-point VRS is commonly used in treatment outcome studies [descriptors used vary by study]

Summary of Scoring:

Available scores: Typically, a score of "0" is given to the least intense descriptor, a score of "1" is given to the next descriptor and so on until each adjective has a score assigned

Weighting: No

Score Interpretation: Higher scores=Higher pain
