Reliability and validity. What accuracy means for this type of scale.
...there is much evidence supporting the validity of VASs of pain intensity. Such scales demonstrate positive relations to other self-report measures of pain intensity. They are sensitive to treatment effects and are distinct from measures of other subjective components of pain. The scores from VASs appear to have th....

To observe that a patient with migraine headaches scores a 10 on a visual analog scale (VAS) of pain intensity conveys little or no information [in the absence of normative information]. However, we know that the average VAS pain severity score for 100 patients with migraine headache is 5.4, with a standard deviation o....

...all that can be determined about the intensity of a person's pain is based on what the patient verbally or nonverbally communicates about his or her subjective experience....a patient is being asked to quantify and average his or her experience of pain over time and situations....a number of studies have reported tha....

Pain intensity is a fairly homogeneous dimension that is relatively easy for adults to identify. [However, there is no way to evaluate the accuracy of these easy estimates.][Also, there is no way to know what the respondent considers pain and not-pain.]

Although individuals interpret measures of pain in different and somewhat idiosyncratic ways, these interpretations can be expected to remain relatively constant within people over time. As a result, they can also provide valid measures of change in pain due to treatment or time. [I think much here can be disputed.]

Moreover, pain intensity itself does not provide a good reflection of either psychological or physical disruption caused by specific disorders.

[Several studies have shown a high correlation (r ~ .8) between recall of average pain over the last week to several weeks and the average of logged pain levels. What these studies can't show is the degree of correlation between recall of average pain when pain levels weren't logged. That is, does the fact of logging....
