Efectiveness of Group Therapy of Mindfulness -Based Stress Reduction on Rumination and Loneliness of Women with Premenstrual Syndrome

The present study was conducted to investigate the effectiveness of group therapy of mindfulness -based stress reduction (MBSR) on rumination and loneliness of women with premenstrual syndrome. The research design was based on a semi-experimental with pre-test-post-test approach and control group. The statistical research population consisted of all women who referred to Dr. Nasr's Obstetrics and Gynecology Center, Tehran, during the first six months of 2018. Of these women, 30 cases were selected as sample using convenience sampling method and based on the inclusion and exclusion criteria, and then, were randomly assigned into an experimental group and a control group (n=15). Participants in experimental group received therapeutic program in eight 90 min-sessions (one session per week); the control group was put on the wait-list for 2 months. In order to collect data, Ruminative responses and social and emotional loneliness for adults scale were used in pre-test-post-test. Multivariate analysis of covariance was used for analyzing the data. Findings from research showed that by controlling the effect of pre-test, a significant difference is observed between the mean of post-test scores of experimental group and control group in variables of rumination, loneliness and its components, including romantic loneliness, family loneliness and social loneliness. Results show that the use of therapeutic techniques of mindfulness -based stress reduction significantly affects the reduction of rumination symptoms, and the loneliness of women with premenstrual syndrome.
