Abstract: (10 Views)
The present study was conducted to compare the effectiveness of Dialectical Behavior Therapy and Metacognitive Therapy on rumination in women with Major Depressive Disorder. This study employed a quasi-experimental design with a pretest–posttest control group and a two-month follow-up. The study population consisted of women diagnosed with Major Depressive Disorder who attended the Jaryan-e Zendegi Psychological Clinic in Tehran during the third quarter of 2025. The sample comprised 48 women who were selected through purposive sampling based on the inclusion criteria and randomly assigned to two experimental groups and one control group (16 participants in each group). The first experimental group received eight sessions of group Dialectical Behavior Therapy, while the second experimental group participated in eight sessions of group Metacognitive Therapy. We collected data using the Ruminative Responses Scale (RRS; Nolen-Hoeksema & Morrow, 1991). Data were analyzed using repeated-measures analysis of variance. The findings indicated that rumination scores in both experimental groups significantly decreased at posttest and were maintained at the two-month follow-up compared with the pretest (p < .01). Furthermore, Metacognitive Therapy produced a significantly greater reduction in rumination than Dialectical Behavior Therapy (p < .01). Overall, the findings suggest that although both interventions were effective in reducing rumination, Metacognitive Therapy demonstrated superior effectiveness among women with Major Depressive Disorder.
