A Visual Analogue Scale (VAS) is one of the pain rating scales used for the first time in 1921 by Hayes and Patterson. It is often used in epidemiologic and clinical research to measure the intensity or frequency of various symptoms.
Visual analogue scales (VAS) are psychometric measuring instruments designed to document the characteristics of disease-related symptom severity in individual patients and use this to achieve a rapid (statistically measurable and reproducible) classification of symptom severity and disease control.
The visual analogue scale (VAS) is a psychometric response scale that can be used in questionnaires. It is a measurement instrument for subjective characteristics or attitudes that cannot be directly measured.
The visual analog scale (VAS) is a validated, subjective measure for acute and chronic pain. Scores are recorded by making a handwritten mark on a 10-cm line that represents a continuum between “no pain” and “worst pain.”
A Visual Analog Scale (VAS) is a simple but valuable instrument that tries to measure a characteristic or attitude that is believed to range across a continuum of values and cannot easily be directly measured.
Background and aims: The Visual Analogue Scale (VAS) is a popular tool for the measurement of pain. A variety of statistical methods are employed for its analysis as an outcome measure, not all of them optimal or appropriate.
Visual analogue scales (VAS) are 10-cm lines anchored at the ends by words that define the bounds of various pain dimensions. The patient is asked to place a vertical mark on the scale to indicate the level of intensity of his or her pain, anxiety, depression, etc.
The Visual Analogue Scale (VAS) has been in use for the measurement of intangible quantities such as pain, quality of life and anxiety since the 1920s [1]. It consists of a line usually 100 mm in length, with anchor descriptors such as (in the pain context) “no pain” and “worst pain imaginable”, depicted in Fig. 1.
Visual Analogue Scales (VAS) provide a simple technique for measuring subjective experience. They have been established as valid and reliable in a range of clinical and research applications, although there is also evidence of increased error and decreased sensitivity when used some subject groups.
The visual analog scale (VAS), as the name implies, uses an analog format, meaning that it represents a continuous range of values.1,2 The most common style used in pain measurement (Fig 1) uses a horizontal line measuring exactly 10 cm (100 mm).3 The patient is asked to make a mark on this line, then the line is measured and recorded in millime...
