Psychogenic pain and psychological variables: a psychometric study.

A sample of 41 women suffering from psychogenic pain according to DSM-III diagnostic criteria were psychometrically studied, in order to ascertain if they showed specific psychological traits or mechanisms. Type A behavior, extraversion, neuroticism, psychoticism and dissimulation and hostility-aggressivity traits were the psychological variables studied both in the pain sample and in a matched control group. Psychogenic pain patients were significantly more neurotic and suspicious and less physically aggressive than healthy subjects and also scored significantly higher in dissimulation, which suggests a tendency to use defense mechanisms of denial.
