title: Factors of human chronic pain: an analysis of personality and pain reaction variables.
abstract: Factor analysis of pain and personality test data obtained from 119 patients with chronic pain syndromes yields seven factors: four composed of personality measures, two involving different psychophysical pain measures, and one sex-related factor. The chief factors, comprising more than 50 percent of the total variance, are "interpersonal alienation and manipulativeness," "clinical pain intensity", and "pain endurance."
