Reproducibility along a 10 cm vertical visual analogue scale

J S Dixon et al. Ann Rheum Dis. 1981 Feb.

Abstract

Reproducibility along a vertical 10 cm visual analogue scale (VAS) was investigated. Eight normal volunteers attempted to duplicate a set of marked VAS. There was a tendency to estimate too high on the scale, and reproducibility was found to be variable along its length. This indicates that the error involved in the use of VASs is even more complex than previously thought.
