both before and after surgery. Because they are both subjective and continuous, they offer a wide variety of positive characteristics for determining when and in what ways pharmaceutical or surgical  intervention makes a difference in a patients sense of whatever problem he or she may be experiencing. However, the subjectivity factor is also often the drawback in the use of  VAS. Another problem is that VAS assessment has often been shown to be open to errors and misinterpretation.

Rodgers - November 2001 -- for more information on using this paper properly!  Introduction Visual analogue scales (VAS) serve as a means to measure various human responses. For example, a person who has had surgery may complete a visual analogue scale in  order to measure his or her pain-related cognitions, intensity, and fears both before and after surgery. Because they are both subjective and continuous, they offer a wide variety of positive  characteristics for determining when and in what ways pharmaceutical or surgical intervention makes a difference in a patients sense of whatever problem he or she may be experiencing, i.e. pain,  apprehension, or other manifestations of their illness or problem. They have also been used to measure appetite or awareness of certain behaviors. However, the subjectivity factor is also often the  drawback in the use of VAS. Another problem is that VAS assessment has often been shown to be open to errors and misinterpretation. Visual Analog Scales and Clinical Studies  Grant, Aitchison, Henderson, et al (1999) conducted a study to assess which subjective scale -- visual analogue scale (VAS), the Borg CR10 (Borg) scale, or the Likert scale (LS) --
