The predictive role of psychosocial stress on symptom severity in premenstrual syndrome.
Twenty-five women with well defined, severe premenstrual syndrome (PMS) were studied prospectively during three consecutive menstrual cycles to examine the association between concurrent psychosocial stress and symptom severity. Stress, mood, physical symptoms, and urinary ovarian steroid metabolites were measured daily. Stress accounted for only 6% and 10% of the unique variance in physical symptom and mood scores, respectively, across the menstrual cycle. In individual woman, there was no association between the severity of symptoms and the cumulative daily stress reported during each cycle. We conclude that in this carefully screened population of women without coexisting psychiatric disorder, PMS symptom severity could not be determined by the amount of psychosocial stress.
