Purpose: Although numerous etiological models of premenstrual syndrome(PMS) such as the biochemical, hormonal, psychosocial models have been proposed, there is no consistent conclusion. Especially, in psychosocial model, state-dependent changes in the perception of stressors according to menstrual cycle phases was suggested for PMS. In this study, we investigated relationship between menstrual cycle and daily minor stressors in young women, and vulnerability to minor stressors in young women with PMS.
Methods: 46 female college students completed modified daily rating form(DRF) of premenstrual symptoms which based on DSM-IV criteria for PMDD, and daily stress inventory(DSI) during at least one menstrual cycle. If the mean score of at least one DRF item during premenstrual phase were more than 3 on 6 point scale and 30% increase in symptom severity during premenstrual phase compared with during postmenstrual phase, they were referred as PMS group(N=20), and the others as non-PMS group(N=26). The event, impact, and impact/event ratio scores of DSI were compared in two groups. Data were analyzed by analysis of variance with repeated measure ANOVA. And post hoc simple; repeated contrast test were performed when indicated by significant repeated measure ANOVA.
Results: In all subjects, the event and the impact scores in premenstrual and menstrual phases were significantly higher than in postmenstrual phase. Among the DSI categories, the impact scores of interpersonal problem and cognitive stressors in premenstrual and menstrual phases were significantly higher than in postmenstrual phase. In PMS group, there was a significant difference between premenstrual and postmenstrual phase in the impact score but not in the event score, and the event and the impact scores were significantly increased in menstrual phase than postmenstrual phase. In non-PMS group, the event and the impact scores in premenstrual and menstrual phases were significantly higher than in postmenstrual phase. There was no significant difference in the impact/event ratio scores in both groups. Between the PMS and non-PMS group, there was significant difference in the impact/event ratio scores in premenstrual phase, but not in the event score and the impact scores at any phase.
Conclusions: Young women may experience more daily minor stressors and may be impacted more severely in premenstrual and menstrual phases than in postmenstrual phase. In premenstrual phase, the young women with PMS are likely to have more vulnerability to daily minor stressors than controls. Further studies using larger sample size with varied age are required.
