A Study of Minor Psychiatric and Physical Symptoms During the Menstrual Cycle

Abstract

Premenstrual tension (PMT) has hitherto not been accurately defined. The term refers to a cluster of symptoms, both psychological and physical, which appear episodically in relation to the phases of the menstrual cycle—either strictly in the premenstruum (Rees, 1953), or also at other times, such as at ovulation (Dalton, 1964). Most previous studies of the syndrome have been ‘retrospective’, i.e. women have been asked to report the presence of PMT during a previous cycle. McCance, Luff and Widdowson (1937) and Altman, Knowles and Bull (1941), who required their subjects to chart mood state daily, pointed to a discrepancy between the frequency of the condition as reported in studies using retrospective questioning and in their own findings. It is hardly surprising that there is controversy concerning the prevalence of a condition which is so poorly defined as is PMT.
