Psychologic factors in chronic headache: assessment by means of the SCL-90-R inventory

Abstract

A survey of the psychologic profile of 540 chronic headache cases, including migraine, tension, and mixed headache, has been carried out with the symptom check list (SCL)-90-R inventory. The results obtained were viewed in relation to sex, age, illness onset, and illness duration. Females showed a positive correlation of somatization with present age and with age at onset of illness and a negative correlation of interpersonal sensitivity, hostility, and paranoid ideation with present age and age at onset of illness. Men showed a negative correlation of obsessive-compulsive and paranoid scores with age and a positive correlation between onset of illness and somatization. Data were also analyzed by cluster analysis, which showed underpopulation with peculiar patterns of symptom profile. A prospective, long-term epidemiologic study could provide more conclusive results.
