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 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 ...
Visual analogue scale (also called the Continuous rating scale and the graphic rating scale) – respondents rate items by placing a mark on a line. 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.
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]
It is an entirely subjective phenomenon. A distinction must be maintained between the stimulus (an external thing that can be directly measured, such as with a thermometer) and the person's or animal's resulting pain perception (an internal, subjective thing that can sometimes be measured indirectly, such as with a visual analog scale).
Drug liking is a measure of the pleasurable (hedonic) experience when a person consumes drugs. [1] It is commonly used to study the misuse liability of drugs. [2] [3] [4] Drug liking is often measured using unipolar and bipolar visual analogue scales (VAS), such as the Drug Liking VAS, the High VAS, the Take Drug Again (TDA) VAS, and the Overall Drug Liking (ODL) VAS.
