Abstract
Commentary: The Historical Roots of Visual Analog Scale in Psychology as Revealed by Reference Publication Year Spectroscopy.
Highlights
Yeung and Wong’s study is an example of how modern information retrieval technology can produce good results
It seems to clearly indicate that Hayes and Patterson (1921) is the origin of the visual analog scale (VAS). This commentary reserves the conclusion that Hayes and Patterson (1921) is the only source of the VAS, and provides a more comprehensive and proper historical perspective for future studies using rating scales
Since the graphic rating scale (GRS) is very similar to the VAS, it seems reasonable to conclude that the VAS originated from Hayes and Patterson (1921)
Summary
The Historical Roots of Visual Analog Scale in Psychology as Revealed by Reference Publication Year Spectroscopy by Yeung, A. Yeung and Wong’s study is an example of how modern information retrieval technology can produce good results. It seems to clearly indicate that Hayes and Patterson (1921) is the origin of the visual analog scale (VAS).
