The language of pain intensity and complexity: new methods of scoring the McGill Pain Questionnaire.

In Part I the McGill Pain Questionnaire was administered to 25 cancer patients, scored and analyzed in the traditional manner. Results indicated that patients with cancer pain appear to be similar in terms of intensity of the pain and the kind of pain which they experience with respect to sensory, affective, and evaluative qualities. Part II presents a new method of administering, scoring, and analyzing responses to the questionnaire, which allows for a more comprehensive interpretation of pain. In Part III the data from Part I are reanalyzed using the new scoring system. As hypothesized, the intensity of cancer pain is higher along the affective dimension than along the sensory. With regard to complexity of the experience of cancer pain, neither the sensory nor the affective dimension is more salient. The new system of scoring and analysis may enable future investigators to specify a unique pain intensity-complexity relationship for each clinical pain syndrome.
