The Relationship between Severity of Premenstrual Syndrome and Psychiatric Symptoms.
OBJECTIVE
Premenstrual syndrome is a common disorder experienced by up to 50% of women during reproductive age. The prevalence of severe form of PMS (PMDD) is 3% to 8 %. Psychiatric disorders in PMS patients have resulted in significant morbidity and in some cases caused resistance to the treatment process.


METHODS
390 participants (264 with PMS/PMDD, and 126 healthy students of University of Guilan) who completed the demographic questionnaire, daily symptom rating (DSR) and the checklist 90-revised (SCL-90-R) took part in this study. This study was conducted using a cross sectional method.


RESULTS
According to repeated measure variance, the mean scores of psychiatric symptoms (Depression, Anxiety, Aggression, Interpersonal sensitivity) in the PMS group were significantly higher than the healthy group (p< 0/05), and increase in severity of PMS from mild to severe was accompanied by increase in mean score of these subscales. There was a significant difference in mean score of depression, anxiety, aggression and interpersonal sensitivity between the 3rd and the 13th day of the cycle. Significant effect of the DSR grouping (PMS and Healthy group) and time interaction emerged in interpersonal sensitivity and aggression, significant effect on the DSR grouping (Mild, Moderate, Severer) and time interaction demonstrated in interpersonal sensitivity.


CONCLUSIONS
Patients with prospective confirmed PMDD seemed to suffer from psychiatric symptoms. Therefore, recognizing co-morbid psychiatric symptoms in patients with PMDD is of prime importance. All healthcare providers should be sensitive to mental status of women with PMS.
