Objectives: The aim of this study was to investigate the effectiveness of metacognitive group therapy and the group training of the life skills on depression, quality of life, the style of ruminative responding, and meta-cognitive believes of the divorced women. Methods: In this quasi-experimental study with uni-variable pre-test post-test design, 24 divorced women who referred for treatment of depression were randomly assigned to one of the two therapeutic groups (meta-cognitive therapy and life skills training). The patients of the metacognitive group therapy received 8 sessions of treatment and also patients in the group of life skills received the 8 sessions of educational program for life skills. Data were gathered in two stages of pre-treatment and post-treatment by using of Beck Depression Inventory-2^nd edition (BDI-II), Metacognitive Questionnaires-30 (MCQ-30), Ruminative Responses Scale (RRS), and World Health Organization Quality of Life-short form (WHOQOL-BREF). Two questionnaires of The Clinical Global Impressions Index (CGI) and Clinical Satisfaction Questionnaire (CSQ) were completed by the participants at the end of interventions. Results: Data showed that meta-cognitive group therapy significantly improved positive beliefs about worry (p=0.03), general clinical improvement (p=0.01) and impression index (p=0.003), and also clinical satisfaction (p=0.04). Yet, there was not any meaningful difference between two groups in the other variables. Conclusion: Metacognitive group therapy improved the positive beliefs about worry, general clinical improvement, and clinical satisfaction in divorced women.
