The Absolute Visual Analogue Scale (AVAS) as a Measure of Pain Intensity

A Comparison of Iran and UK EQ-5D-3L Value Sets Based on Visual Analogue Scale

Background Preference weights for EQ-5D-3L based on visual analogue scale (VAS) has recently been developed in Iran. The aim of the current study was to compare performance of this value set against the UK VAS-based value set.   Methods The mean scores for all possible 243 health states were compared using Student t test. Absolute agreement and consistency were investigated using concordance co...

The validation of visual analogue scales as ratio scale measures for chronic and experimental pain.

Visual analogue scales (VAS) of sensory intensity and affective magnitude were validated as ratio scale measures for both chronic and experimental pain. Chronic pain patients and healthy volunteers made VAS sensory and affective responses to 6 noxious thermal stimuli (43, 45, 47, 48, 49 and 51 degrees C) applied for 5 sec to the forearm by a contact thermode. Sensory VAS and affective VAS respo...

Visual analogue measurement of pain.

Two separate studies were carried out to determine if three visual analogue scales for various feelings including pain could be marked consistently by patients, without reference to previously completed scales. Sixty patients undergoing extraction of their lower third molars had measurements of acute preoperative anxiety, expected postoperative pain and postoperative perceived pain three times ...

Comparative cut-off value setting of pruritus intensity in visual analogue scale and verbal rating scale.

Semantic Intensity: a measure of visual relevance

This work deals with the quantification of the effects of discarding large amounts of irrelevant information in sets of images. In particular, the trade-off between the cost of losing information and the benefit of increasing perceptual speed is examined. We look for a measure of such trade-off by a new measure, 'semantic intensity', broadly defined as the ratio of amount of 'meaning' conveyed ...
