Recent advances in methodologies for Internet-based research3 include the development and evaluation of visual analogue scales for use in Internet-based questionnaires.1
The visual analogue scale or visual analog scale (VAS) is a psychometric response scale which can be used in questionnaires. It is a measurement instrument for subjective characteristics or attitudes that cannot be directly measured. When responding to a VAS item, respondents specify their level of agreement to a statement by indicating a position along a continuous line between two end-points. This continuous (or "analogue") aspect of the scale differentiates it from discrete scales such as the Likert scale. There is evidence showing that visual analogue scales have superior metrical characteristics than discrete scales, thus a wider range of statistical methods can be applied to the measurements.1
The Compuload Analogue Dial Scale is a cost effective means of safely weighing your goods prior to loading trucks as well as checking incoming goods. Analogue scales assist in the prevention of overloading equipment and transport, therefore reducing your risk of overloading fines.
In this article we have described the flexible use of visual/verbal analogue scales in the dental surgery. It takes very little time to describe to the patient and seconds to use as a monitoring device during treatment. If used to address the individual's problems (fear/worry, fear of pain, fear of betrayal or lack of trust, poor self-esteem and few positive coping strategies) that should have been identified during history taking, the result is a far more accurate understanding of the patient's perceptions by the dentist. In addition, the patient should feel better understood, less vulnerable and more cared for.
