Treatment of premenstrual syndrome: Appraising the effectiveness of cognitive behavioral therapy in addition to calcium supplement plus vitamin D.

Premenstrual syndrome (PMS) consists of repetitious physical and psychological symptoms. The symptoms occur during the luteal phase of the menstrual period and cease when the menstrual period starts. This study included pre-test and post-test experiments between a control group and a test group. The statistical population involved 40 females, chosen based on multistage cluster sampling. The participants were then divided into four groups to undergo treatment with calcium supplement plus vitamin D together with cognitive behavioral therapy (CBT), and were screened with the Premenstrual Syndrome Screening Test (PSST). The pre-test and post-test scores in the PSST, the General Health Questionnaire (GHQ-28), and Bell's Adjustment Inventory (BAI) were used as assessment tools (p < .05). According to the parameters of PMS symptoms, when evaluating the pre-test and post-test scores, the overall score of each individual in the experimental group was improved and a significant effect for the combination of calcium supplement plus vitamin D together with CBT was observed in comparison to the post-test control group. A comparison of multivariate analysis of covariance (MANCOVA) results collected from the pre-test and post-test scores revealed that the method of treatment was beneficial for PMS, adjustment, and general health.
