Which scale captures qualitative descriptions of pain across multiple dimensions?

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

Answer: (A)

Capturing qualitative, multidimensional descriptions of pain requires a tool that offers descriptors across several domains. The scale designed for this purpose presents a wide range of words that patients can select to describe the quality of their pain, organized into sensory (how it feels), affective (how it feels emotionally or affectively), and evaluative (overall intensity or magnitude) categories. By allowing patients to choose from many descriptors, it yields a rich, nuanced profile of their pain that goes beyond a single number or a few broad terms. In contrast, the visual analog scale records pain intensity along a continuous line, giving a single dimension of severity. The graphic rating scale typically anchors a single dimension like overall severity as well. The verbal rating scale uses a few qualitative categories (for example, mild, moderate, severe), which captures some qualitative information but collapses it into a limited number of levels and doesn’t map out multiple sensory and affective qualities. Therefore, for qualitative descriptions across multiple dimensions, the McGill Pain Questionnaire is the best choice.
