Which pain scale has a line with contrasting descriptors at either end of the line?

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

Answer: (A)

The main idea here is how pain intensity is quantified on a single, continuous scale. The Visual Analog Scale uses a straight line with contrasting anchors at each end—usually something like “no pain” on the left and “worst pain imaginable” on the right. The person marks a point along the line to reflect how much pain they feel. The distance from the left end is then measured (often in millimeters), giving a precise, continuous value for pain. This format provides finer discrimination than scales that rely on discrete categories or descriptive words. The other methods typically use individual categories, numeric steps, or words to describe pain, which limits the granularity of the measurement. The McGill Pain Questionnaire, for example, uses multiple descriptive terms and intensity ratings, not a single line with end anchors. The Visual Rating Scale and Graphic Rating scales involve different formats that aren’t a single continuous line with opposite-end descriptors. So, the line with contrasting descriptors at either end is characteristic of the Visual Analog Scale.
