Mcgill Pain Scale Questionnaire

Mcgill Pain Scale Questionnaire and its short form provide the patient with three major classes of word descriptors (sensory, affective, and evaluative) to describe their pain experience. These designations are used to differentiate patients who have a true sensory pain experience from those who think they have experienced pain (affective pain state).

It was developed at by Dr. Melzack at McGill University in Montreal Canada and has been translated into several languages.

McGill Pain Questionnaire provides quantitative information that can be treated statistically, and is sufficiently sensitive to detect differences among different methods to relieve pain.

Short-Form McGill Pain Questionnaire

The short-form McGill pain questionnaire:

  1. descriptors 1 to 11 represent the sensory dimension of pain experience,
  2. descriptors 12 to 15 represent the affective dimension.
  3. Each descriptor is ranked on an intensity scale of 0 = none, 1 = mild, 2 = moderate, 3 = severe.

The present pain intensity (PPI) of the standard long-form McGill pain questionnaire and the visual analog scale are also included to provide overall intensity scores. For actual examination, line would be 10 cm long.
