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...
متن کاملEnhancements to the Visual Analogue Scale, VAS, for listening tests
Three methods for perceptual rating of audio stimuli were compared. The Visual Analogue Scale, VAS, was implemented as two computer programs and compared to the VAS on paper. The first program is a straight-forward implementation, the second program introduces the Visual Sort and Rate method, VSR. VSR allows the subject to compare stimuli of similar rating to each other, thus making the orderin...
متن کاملClinical stress assessment using a visual analogue scale.
BACKGROUND Clinicians increasingly require short, efficient methods for assessing distress, both in applied research and clinical settings. Most of the available questionnaires are unsuitable for busy clinical settings. The visual analogue scale (VAS) is widely but empirically used to assess perceived stress. AIMS To provide evidence on two of the psychometric properties of the VAS: its discr...
متن کاملReproducibility along a 10 cm vertical visual analogue scale.
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.
متن کاملThe visual analogue scale in the assessment of grip strength.
The accuracy of information derived from a visual analogue scale has been assessed by comparing the measured grip strength of 100 subjects against their estimate of grip strength scored on a visual analogue scale. There was relatively poor correlation between the measured and assessed values, suggesting that similar inaccuracies may occur when the scales are used to assess subjective phenomena.
