I want to know the answer to the following question:
How many dimensions did Melzack and Casey describe pain in terms of?
All the background I'm provided with is that "In 1968 Ronald Melzack and Kenneth Casey described pain in terms of its three dimensions: "sensory-discriminative" (sense of the intensity, location, quality and duration of the pain), "affective-motivational" (unpleasantness and urge to escape the unpleasantness), and "cognitive-evaluative" (cognitions such as appraisal, cultural values, distraction and hypnotic suggestion).". Is that enough to answer the question?
Answer: yes
