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]
Reips and Funke (2008) [21] show that this criterion is much better met by a visual analogue scale. In fact, there may also appear phenomena which even question the ordinal scale level in Likert scales. [22] For example, in a set of items A, B, C rated with a Likert scale circular relations like A > B, B > C and C > A can appear.
Visual analogue scale (VAS): Respondents are asked to rate a state of ill health on a scale from 0 to 100, with 0 representing being dead, and 100 representing perfect health. This method has the advantage of being the easiest to ask, but is the most subjective.
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]
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.
