Abstract

Among a sample of 40 severe migraine sufferers, males and females displayed common personality profiles. Both sexes exhibit heightened scores on those MMPI clinical scales associated with neuroticism (hypochondriasis, depression and hysteria). Female migraine sufferers were further characterised by elevated scores on the primary scales constituting the psychotic tetrad (paranoia, psychaesthenia, schizophrenia, and hypomania). Migraine females appeared to differ from male patients with respect to a dimension associated with sex-role conformity (loaded on the L-scale and masculinity-femininity). The implication of these results are considered.
