A visual analogue scale (VAS) is a psychometric response scale which can be used in questionnaires.

The recent advances in methodologies for Internet-based research (e.g. ) include the development and evaluation of visual analogue scales for use in Internet-based questionnaires.

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.

In humans, evaluation of Surrogate endpoints like electroretinography, auditory evoked potentials and visual analogue scales also suggested positive nootropic effects, but larger studies with hard endpoints are missing.
