Which pain scale is described as a horizontal line with anchor points at each end and descriptors spread along the line?

• A. Visual analog scale
• B. Visual rating scale
• C. Number scale
• D. McGill pain questionnaire

Answer: (A)

This item tests your understanding of the Visual Analog Scale. It is a horizontal line with endpoints labeled to represent no pain on one end and the worst possible pain on the other. Descriptors or cues can be spread along the line to guide the patient, but there are no discrete steps—patients indicate their pain by placing a mark somewhere along the line. The score is then measured as the distance from the no-pain end (often in millimeters), giving a continuous measure of pain intensity from 0 to about 100. This setup makes the VAS more sensitive to small changes in pain than scales with fixed categories or numbers. It differs from a simple numeric rating scale (which uses distinct numbers) and from the McGill Pain Questionnaire (which is multi-item and descriptive), while a visual rating scale or other formats may use fewer categories or different structures.
