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 ...
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 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 ...
As with many visual analog scales, the feeling thermometer has been criticised for its limits of accuracy, precision, range and reliability. The process of using the measurement allows for a high level of bias from participants when answering questions and in turn providing their ratings.
More recently, Campos and Pérez-Fabello evaluated the reliability and construct validity of the VVIQ and the VVIQ2. [3] Cronbach's reliabilities for both the VVIQ and the VVIQ-2 were found to be high. Estimates of internal consistency reliability and construct validity were found to be similar for the two versions.
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 ...
