This research paper: This 5 page report discusses visual analogue scales (VAS) and how they 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 patient’s 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. Bibliography lists 5 sources.
