Visual analog scale

from Wikipedia, the free encyclopedia
A visual analog scale for the question "How severe is your pain right now?"

The visual analog scale ( VAS ) is a scale for measuring primarily subjective attitudes.

It is often used in pain research and pain therapy . Mostly it is a line, the endpoints of which represent extreme conditions, such as B. "no pain" and "unbearable pain". The respondent marks his / her subjective sensation with a vertical line on the line. The given value is then quantified by the respondent as a percentage or using a defined scale, usually from 0 to 10. However, the respondent does not see the discrete scales.

history

A visual analog scale (as a graphic rating scale ) was first published in 1921 by Hayes & Patterson as a new method for assessing workers by their superiors; two years later Freyd provided a more detailed list of the advantages and disadvantages of visual analog scales.
