Abstract: (44 Views)
The present study aimed to determine the effectiveness of group-based Acceptance and Commitment Therapy on emotional self-regulation and rumination in obese adolescent girls. This research was quasi-experimental with a pretest–posttest design and a control group. The statistical population consisted of obese adolescent girls aged 13 to 16 years from first-cycle secondary schools in the city of Tehran during the 2024–2025 academic year. From among them, 30 eligible participants were selected through convenience sampling and were randomly assigned to the experimental and control groups (15 participants in each group). The experimental group participated in eight 90-minute sessions of group-based Acceptance and Commitment Therapy, while the control group received no intervention. The research instruments included the Self-Regulation Questionnaire (BSF; Bouffard, 1995) and the Rumination Questionnaire (RRS; Nolen-Hoeksema & Morrow, 1991). Data were analyzed using multivariate analysis of covariance. The findings showed that, after controlling for the effect of the pretest, there was a significant difference at the 0.05 level between the posttest mean scores of emotional self-regulation and rumination in the experimental and control groups. Accordingly, it can be concluded that group-based Acceptance and Commitment Therapy is effective in improving emotional self-regulation and reducing rumination in obese adolescents.
