THE PREMENSTRUAL PHASE AND REACTIONS TO AVERSIVE EVENTS - A STUDY OF HORMONAL INFLUENCES ON EMOTIONALITY

Fifty-eight normal cycle, healthy women were confronted with an aversi ve, anger-provoking situation in the laboratory. Eighteen women were t ested in their follicular phase. A further 40 women were tested in the premenstrual phase, half of whom reported suffering from complaints o f premenstrual emotional lability and irritation, the other half repor ted being without premenstrual problems. Apart from a strong effect of emotion induction on cardiovascular arousal and anger-related moods i n the follicular and premenstrual groups, a premenstrual phase effect was also demonstrated, with premenstrual women showing evidence of bei ng more affected by the manipulations on systolic blood pressure and i ntensity of angry behaviour during anger provocation. Furthermore, som e differences were found between those subjects who reported suffering from premenstrual complaints and those free of such complaints, among the most interesting ones being differences in cortisol level precedi ng the experimental session, in intensity of angry behaviour, and in r eport of anger intensity at debriefing. The study indicates that the p remenstrual phase may have the effect of making women more susceptible to responding emotionally to negative life events. Copyright (C) 1996 Elsevier Science Ltd
