The Effectiveness of Transdiagnostic Treatment Program on Clinical Symptoms and Emotion Regulation in Girls Adolescents with Premenstrual Syndrome

Background: Premenstrual Syndrome (PMS) is the experience of some physical and psychological symptoms periodically in the last days of the menstrual cycle that interferes with academic, social and family functioning. We aimed to evaluate the effectiveness of Transdiagnostic Treatment Program (TTP) on clinical symptoms and emotion regulation in girl's adolescents with PMS.

Methods: This experimental trial study was carried out on 32 girls adolescents with PMS referred to two medical centers located in Tehran, Iran from Mar 21, 2019, to Oct. The patients randomized in 2 groups, 1-intervention (n=16, 8 sessions, 90-minute weekly) and 2-control (n=10).The PMS Screening Tool (PSST) and Emotion Regulation Questionnaire (ERQ) before and after treatment were filled out by participant. The SPSS software and P<0.05 considered for data analysis and as significant levels respectively.

Results: The study sample was 32 girls adolescents with PMS (mean age intervention and control were 16.30±2.02 and 16.40±1.6, P=0.915). The score of two questionnaires, PSST (symptom, effect) and ERQ (cognitive reappraisal, suppression) between two groups in before treatment were the same. After intervention the change of variable symptom (-1.05 vs -0.02, P<0.001), effect (-0.53 vs -0.04, P<0.001), cognitive reappraisal (0.67 vs 0.02, P<0.001) and suppression (-0.64 vs -0.07, P<0.001) were significant between two groups.

Conclusion: TTP is an effective technique for controlling clinical symptoms and emotion regulation in girl's adolescents with PMS.
