title: Premenstrual tension syndrome symptom clusters. Statistical evaluation of the subsyndromes.
abstract: Premenstrual symptoms were evaluated in a group of women with severe premenstrual tension syndrome. Factor analysis was performed in order to establish the nature of symptom clusters in this sample. Similar to clinical observations reported on before, the results revealed two distinct clusters of emotional/behavioral symptoms and two of physical symptoms.
