VAS

VAS

A visual analogue scale (VAS) is a psychometric response scale that allows subjects to indicate their level of agreement with a statement by marking a position along a continuous line between two end-points. Additionally, participants may use a VAS to evaluate a subject task by marking a position along a continuous line with reference to descriptions on the edges of the scale.From: Advances in Human Factors, Ergonomics, and Safety in Manufacturing and Service Industries [2019], Handbook of Automotive Human Factors [2019]

The VAS scale is widely used in subjective evaluation of many variables. It consists of a row (horizontal or vertical), with a certain length (often 10 cm) and anchors that represents the maximum and minimum criteria of the variable to be measured (Bacci, 2004). Collins et al. (1997) recommends the use of this type of scale at the expense of categorical scales, claiming to be more precise. Huskisson (1983 apud Björkstén et al., 1999) also recommends the use of this method since VAS scores are highly correlated, simple to measure and interpret, sensitive, easily reproducible, and universal.

Muscle soreness upon palpation of the upper arm of the elbow joint was quantified using a visual analogue scale with a 100-mm line indicating “no pain” at the left end and “extremely sore” at the right end (Tanabe et al., 2019). During this measurement, the participants were instructed to sit on a chair with the arm relaxed, and one skilled investigator palpated the biceps brachii. The same investigator performed all tests, and the pressure of palpation was maintained as consistent as possible on all occasions. The intra-rater reliability of VAS assessed by ICC was 0.95.
