This continuous (or "analogue") aspect of the scale differentiates it from discrete scales such as the Likert scale. There is evidence showing that visual analogue scales have superior metrical characteristics than discrete scales, thus a wider range of statistical methods can be applied to the measurements. [1] The VAS can be compared to other ...
In 1921, Hayes and Patterson used the visual analog scale (VAS) method for the first time to measure and record the pain intensity of patients' medical issues. [7] Throughout the mid-1900s, different types of visual analog scales were developed such as the traditional, graphic and numeric rating scales that all use a continuous line of ...
The line is usually labeled at each end. There are sometimes a series of numbers, called scale points, (say, from zero to 100) under the line. Scoring and codification is difficult for paper-and-pencil scales, but not for computerized and Internet-based visual analogue scales. [9]
The EQ-5D essentially consists of two pages: the EQ-5D descriptive system (page 2 of the questionnaire) and the EQ-5D visual analogue scale (EQ VAS) (page 3 of the questionnaire) (Video: Explaining the EQ-5D in about Two and Half Minutes). As noted above, ‘EQ-5D’ is not an abbreviation and is the correct term to use when referring to the ...
The visual analog scale is a visual scale that has two endpoints: "no pain" and "pain is as bad as it could be". When it was first created people had to physically write their answers on the scale. There are mechanical ones now to make the scoring of them easier. [9]

The term is a contraction of the words "discretized" and "analog" [1] and is also known as categorical analogue scales. [ 2 ] As a scale, it is a type of ordered-metric scaling that yields a scale with internal reliability, and scale-points in excess of the number of initial anchors, more than would be the case with the Likert scale, though not ...
