Neurotic traits and disease duration in headache patients

The purpose of this study was to test the hypothesis that duration of illness is correlated with neurotic personality traits. Four hundred and eighteen patients with migraine, tension, and mixed headaches were studied. The MMPI was used to evaluate the patients' personality characteristics. Scales employed were: scale 1--hypochondriasis, scale 2--depression, scale 3--hysteria, and scale 7--psychasthenia. The MMPI scale scores were analysed with regard to sex, diagnosis, and duration of illness. Patients with mixed headaches showed significantly more elevated scores on the MMPI scales than those suffering from migraine and tension headaches. No correlation was found between any of the MMPI scale scores and the duration of illness. No interaction was found between duration of illness and the diagnostic categories of headache in determining the MMPI neurotic scale scores. It is hypothesized that the higher MMPI scores found in patients with mixed headache is characteristic of these patients.
