A card sort method of pain assessment . - A.E. Reading and J.R. Newton, J. psychosom. Res., 22 (1978) 503--512

This paper considers the problem of measuring the subjective report of clinical pain. In view of the limitations of existing approaches (rating scales and questionnaires), an alternative method of pain assessment is described. This approach derives from a multidimensional view of pain. The test is in the form of paired comparisons and is designed to provide a score from 1 to 4 of the intensity of a range of pain qualities. The paired comparison format also allows the reliability of the test to be determined. Sufficient consensus was found over the meaning and relevance of words from a preliminary survey of 200 women with pelvic pain (dysmenorrhea and I.U.D. related) to allow a standard test to be developed. The reliability of the test was found to be acceptable and its clinical advantages l~romiaing during the course of an 18-month period when it was administered 213 times to Caucasian women with pelvic pain. High validity for the test was found both in terms of its internal structure and in terms of associations with other pain indices, such as the use of analgesics.

The effect of random temporal distribution of stimulus on the threshold for electrically-induced pain. -- F.G. Spear and N.B. Worrall, J. psychosom. Res., 22 (1978) 531--533

Pain and severe pain thresholds with electrical stimulation were estab- lished for equivalent stimuli delivered as random and regular temporal pulse patterns. The thresholds were significantly lower for stimulation of an irregular type. It is suggested that this finding supports Goody's hypothesis that pain sensation is a consequence of stimulation which is difficult to structure.

The difference between subjective intensity of pain for repeated identical stimuli was measured at high and low stimulus levels in 20 subjects. A signifi- cant (P < 0.01) correlation was found between this difference and the stimulus level. For low intensities of stimulus subjective pain diminished; at high intensities it increased. The changeover point was slightly below the severe pain threshold. It is suggested that this may imply the possibility of desensitizing people to painful stimuli.
