Abstract
  A short form of the McGill Pain Questionnaire (SF-MPQ) has
  been developed. The main component of the SF-MPQ consists of 15
descriptors
  (11 sensory; 4 affective) which are rated on an intensity scale as 0 =
none,
  1 = mild, 2 = moderate or 3 = severe. Three pain scores are derived
from the
  sum of the intensity rank values of the words chosen for sensory,
affective
  and total descriptors. The SF-MPQ also includes the Present Pain
Intensity
  (PPI) index of the standard MPQ and a visual analogue scale (VAS). The
SF-MPQ
  scores obtained from patients in post-surgical and obstetrical wards
and
  physiotherapy and dental departments were compared to the scores
obtained
  with the standard MPQ. The correlations were consistently high and
  significant. The SF-MPQ was also shown to be sufficiently sensitive to
  demonstrate differences due to treatment at statistical levels
comparable to
  those obtained with the standard form. The SF-MPQ shows promise as a
useful
  tool in situations in which the standard MPQ takes too long to
administer,
  yet qualitative information is desired and the PPI and VAS are
inadequate.

Abstract
  The McGill Pain Questionnaire consists primarily of 3 major
  classes of word descriptors--sensory, affective and evaluative--that
are used
  by patients to specify subjective pain experience. It also contains an
  intensity scale and other items to determine the properties of pain
  experience. The questionnaire was designed to provide quantitative
measures
  of clinical pain that can be treated statistically. This paper
describes the
  procedures for administration of the questionnaire and the various
measures
  that can be derived from it. The 3 major measures are: (1) the pain
rating
  index, based on two types of numerical values that can be assigned to
each
  word descriptor, (2) the number of words chosen; and (3) the present
pain
  intensity based on a 1-5 intensity scale. Correlation coefficients
among
  these measures, based on data obtained with 297 patients suffering
several
  kinds of pain, are presented. In addition, an experimental study which
  utilized the questionnaire is analyzed in order to describe the nature
of the
  information that is obtained. The data, taken together, indicate that
the
  McGill Pain Questionnaire provides quantitative information
  that can be treated statistically, and is sufficiently sensitive to
detect
  differences among different methods to relieve pain.
